Chapter 4

Once outside, standing beside his truck, he immediately used the Vapor Sense to sense the surrounding area through water vapor in the air, being cautious of Assassin's presence.

He remembered that Assassin in this Holly Grail War had an ability to split himself into many existences, and together with his Presence Concealment skill, he had been given a reconnaissance duty.

Thanks to the fact that he was on the outskirts part of the city, or he just simply had a good luck, Sena found nothing magical around.

But to make sure, he scanned the area two more times, and stopped when he still couldn't find any magical presences.

'Alright.' He nodded then activated his ability.

Water started to gathered in front of him, took a humanoid form, then a perfect copy of himself was standing before him.

He created a clone.

At the same time, when the clone creation process was completed, he got new sensory feedbacks apart from his own.

He created the clone not only in Naruto's way, but also in Pain's Six Path way, and Shadow Monarch's way.

So this clone was an extension of himself, an avatar, which he controlled himself remotely. And similar to Shadow Army, as long as he provided it with energy, it would regenerate no matter how damaged it was.

He could execute his every abilities through it as well when he was in control.

Simply put, this clone was his proxy.

He had the absolute defense, sure, but it was better safe than sorry.

He would do it in Nagato's way, using avatar as proxy, while he himself would became a shut-in and holed up in his indestructible Isekai Truck.

Absolute Defense+Indestructible Isekai Truck=Double Assurance.

Triple if we counted the travel function as an escape way as well.

'It's weird, but I'm fine.' He couldn't help but commented when he checked his control over the clone or avatar.

This was his first time using the ability, but thanks to the effect of absolute mastery which the AWE gave him, he could use it just fine, as if he had been using it for the entirety of his life.

Even the new experience of receiving sensory feedbacks from two bodies at the same time didn't bother him at all.

He felt weird, sure, because it was a new experience for him, but apart from that, he was fine.

Let alone one, he believed that, even if he created many of them and controlled them simultaneously, he could do it just fine.

After his check and inspection of the control was done, with the ice dagger in hand, he moved forward.

Swiftly, he slashed the avatar's neck, and it cleanly beheaded.

The head hit the ground, and with a splash, it reduced into water.

As for the body part, water wriggled out of the beheaded neck, took a shape of a head and a brand new head was formed.

Sena was stunned, not surprised by how the head regenerated, nor how fast the process was, but because the feedback he received.

He gulped and rubbed his own neck.

'You are a big idiot, Sena. That was too hasty of you...'

He regretted how casual he was with the test and for not prepared himself beforehand.

When he created the avatar, he made sure to not received any painful feedbacks when it was damaged. And that fact catched him off guard just now.

There was no pain, sure, but the sensation of being beheaded was not an enjoyable experience.

He let out a sigh and relaxed his nervous mind.

Looked at the avatar to find any abnormalities, he nodded, satisfied when he found none, and returned back into the truck.

He turned on the camuflage mode of the truck, made it transparent and undetectable from the outside.

After that, he set the seat and recliner comfotably, then closed his eyes to put all his concentration into controlling the avatar.

Controlling the avatar, he unfolded his wings and took off, flew high in the sky.

He stopped when he thought he was high enough and expanded the range of the his Vapor Sense.

Water vapor was everywhere in this city, thanks to the river and the sea nearby, so his senses covered the whole city easily.

His Vapor Sense was similar to how Rimuru perceived the outside world through magicules around.

So through the vapor, he could see everything in the city.

What catched his attention the most though, was the servants.

Some of them were in astral form, while another materialized themselves in physical form.

He was glad that even in their astral form, he still could sense them through the vapor, as their energy brushed against it.

'Found you!'

Sena was looking for where the Matou Residence was, and found them after a while, thanks to Berserker's existence in it.

Took a deep breath, he prepared himself.

'Covert and swift.'

He readjusted his mind and made a simulation in his mind.

Knowing that he had nothing to lose in this boosted his confidence tremendously.

After all, no matter what happened, he was safe inside the Isekai Truck, and could run to another world immediately if everything become worse.

Certain and confident with his plan, he started to move.

First he located every Assassins around, and the other reconnaissances as well.

'Far enough... Good.'

He located all of them, then with Water Movement, teleported to an area outside of their observation range.

Water Movement was an ability that inspired by how Tempest Wolf teleported using shadow as medium. But his was using water vapor instead, so it was more like Minato's Hiraishin in appearance.

Not wasting his time, he encased himself in a water bubble to make himself undetectable and invisible.

As the water bubble doing it's job by manipulating the light reflection, he became invisible, and immediately, he flew towards the Matou Residence.

He never tore his attention from the reconnaissances the other masters put around the area, and viewed everything carefully.

He once again couldn't help but glad that AWE gave absolute mastery over the abilities it provided. That way, he could use them very easily.

Soon he arrived at the outside of the barrier, or bounded field, that the Matou had.

He observed it for a while, and could tell roughly from the knowledge he got from the autopilot, that the thing was a decent one.

Matter not, though, he could destroyed them easily.

He didn't know much about the Sena Sitri prior to his reincarnation. But if it was about Sena Sitri who was his autopilot mode, he knew about them pretty well.

Rather, he remembered almost everything from the moment he was born. Not sure if it was an autopilot mode thingy, or a deliberation from the guy who reincarnated him.

But about his autopilot mode, to put it simply, was a capable person.

He was a learner.

Well, without a doubt, the guy programmed it that way. And he was grateful for that, because now, the knowledge and experiences became his.

His autopilot mode was a learner from a tender age.

He learned as many things as he possibly could. And being a programmed mode, his learning ability was ridiculously fast. After all, learning process for it was just an act of saving data in the memories.

Maybe that was why he remembered almost everything?

'Not sure why the dude programmed the mode to learn how to cook to that extent, though.' He thought as he looked at the mechanism of the barrier.

The other things, he understood the necessity.

But putting so much effort to learn how to cook...

'Well... Taking into consideration of the existence of 'The Ultimate Mother, Emiya' in this world, maybe that was a very important skill to have?' He wondered.

Using his inability to exert the full potential of his Demonic Power as excuse, not only devil magic, his autopilot mode started to learn about magic of different system as well.

From the system used by human, to Nordic and Greek.

He learned about Rune as well, and even about Youjutsu of the Yokai.

He learned many things. Artifacts, Alchemy, Barrier, etc.

It didn't matter whether he could use them or not, he still learned about them, and told people around him who asked, that he learned them for reference.

No one knew how much he got from that extensive learning, and more clueless about his true capabilities because of that.

The autopilot never show his true capabilities to anyone after all, for an obvious reason.

'I bet my money the dude programmed it that way for background story reason.' Sena rolled his eyes.

After all, the kidnapping and eventual death of Sena Sitri would be an impossible thing to happen if his true capabilities was known.

He was not the strongest, sure, but Sena believed that his autopilot mode was a solid Ultimate Class.

'An Ultimate Class devil actually kidnapped by a bunch of High Classes and died because of that. What a big ass of plot hole.' Sena commented in his mind.

But at the end of the day, the knowledge and experience were his now, so it was good and a win for him.

He shook his head to put away the distracting thought, and put his full attention to the current situation again.

Certain that it was fine to destroy the barrier, he stealthily encased the whole Matou Residence with a big and transparent water bubble.

Different from the one he used before, this one had the ability to show fake images to the outside, blocked sounds, energy fluctuations, etc. To make people outside oblivious about what happened inside.

At the same time, it would confined the ones inside and forbid entry from the outside.

The area encased in a short time, and Sena immediately activated the bubble.

He created many spears of ice, then launched it at some spots to destroyed the bounded field, and it destroyed with a "crack" sound.

With a wave of his hand, the invisible bubbly encased him disappeared, revealed his existence.

Right after that, buzzing sounds could be heard as worms started to flooding out of the mansion.

"Aaarrrgghhh!!!"

Following that, with a roar, Berserker materialized himself from the astral form as well, to face the intruder.

"Here you are..." Sena muttered, as chain appeared out of nowhere with a clanking sounds around Berserker.

Not giving the mad servant any time to react, Sena chained him immediately, incapacitated him.

Sena poured his mana like crazy as he created the chain, to make it appeared as Instantaneous as possible, and as durable as possible.

Sena didn't want to waste his time and gave his everything in capturing Berserker.

Berserker grabbed a part of the chain and spread his mana into it, but as the part he touched started to turned black, the ice chain sucked that mana, returned the chain back to normal condition.

'I know your abilities, and I made a countermeasure for it.' Sena thought with a grin.

"Aaarrrgg-"

With yet another roar, Berserker tried to exert his strength to realeased himself from the bind, but could not as the chain, after incapacitated him, froze him into ice sculpture immediately.

Not only got a supply from sucking Berserker's mana, but Sena keep pouring his mana into the chain with reckless abandon, made it insanely powerful at showing it's capabilities.

At the same time he used the chain to took care of Berserker, Sena created Frost Mist to handle the worms, spreading it to the surrounding area, enclosed everything in mist in no time.

Frozen, the worms fell one by one as they tried to pass through the mist.

'Heh! Every single one of these abilities crazily consume my mana! But Insta Recovery insanely keep up with them!! Spamming these abilities to their max potentials is ridiculously easy as fuck!'

Sena was amazed, thrilled, and excited, as he grinned in delight.

Even spamming the abilities like nothing, his mana reserve never decrease. Not even a bit!

His thought then interrupted by a sudden energy fluctuations coming from the chained and frozen Berserker.

But nothing happened, as the chain sucked them immediately.

"Summoning back Berserker using command spells? Sorry buddy, I am prepared."

One of his objectives for coming here was to capture Berserker, to create a Water Soldier, his version of Shadow Monarch's Shadow Soldier. So how could he let the prey escape after the efforts he exerted to capture it.

He came prepared!

So he added a characteristic to the chain, to negates any summoning attempt the master would do with their Command Spells when their servant was captured by him.

Looking at the frozen Berserker chained, he smiled as more confidence blooming in his heart.

'This is fun!'

He was cheating and it was not a fair fight.

He knew that.

He could have any abilities related to water with AWE. No matter how powerful, as long as it was water-based, it possible.

Insta Recovery would make him always in prime condition. No matter how much he used one or many abilities, it matter not. He could spam any abilities, no matter how powerful they were, easily like nothing. It was as effortless as randomly throwing a rock.

'Luckily catching this guy was easier than I thought.' He sighed in relief.

'Well... then...' He looked at the directions of the mansion, and with a hand on the ground,

'Ice Age...'

Using the ability, he poured his mana crazily again.

As result, the whole place was frozen Instantly, along with it's inhabitants.

They were alive though. He made sure of that.

He wanted to do it from the start, but as Berserker was in his astral form, probably not to burden his dying master, to capture it, he need to make Berserker materialized first.

Now everything was under control, Sena strolled ahead.

Arrived at where Berserker chained and frozen, he reached out and streams of water came out of his hand, enveloped it in a spherical shape.

Using the Water Soldier ability, it copied everything about Berserker as the water started to glow.

Different from the Shadow Soldier ability, his Water Soldier could be used on someone who still alive as well, by copying them like the Grail copied Heroic Spirit in the Throne of Heroes.

But different from the Grail where the spirit copied would have their own free will, the one copied by Water Soldier ability would have absolute loyalty to him, just like how Shadow Soldier worked.

"!?" As it started and his mana fueled the process, he was surprised by the amount of mana he needed to copy Berserker.

But that was it, he shrugged it off and continued.

The process was not that long. Less than ten seconds later, the sphere of water distorted, extracted itself from the frozen Berserker, constructed a humanoid form.

The process ended and Sena retrieved his outstretched hand as a perfect and complete copy of Berserker, Lancelot, was kneeling in front of him.

"Heh!" Sena grinned and chuckled lightly, as he looked at his successful attempt.

He used Water Soldier ability again, and streams of water came out of him, and formed nine figures.

Nine exact copies of Lancelot!

'Fuck yeah!!!' He exclaimed excitedly in his mind looking at ten Berserker Lancelot in front of him!

As Sena copied Berserker before, the data was stored in him. And using that stored data, he could create as many Berserker Lancelot as he wanted with Water Soldier ability, just like how Naruto created his Shadow Clone.

The most insane part of it was, all of them, and every single one of Water Soldier he created, would have everything the source had. Noble Phantasm included!

And using the data, Sena himself could have one for himself!

That was how his Water Soldier ability worked.

It worked based on Naruto's Shadow Clone, Shadow Monarch's Shadow Soldier/Armies, Nagato's Six Paths, and how grail summon and or create Heroic Spirit by copying their data in the Throne of Heroes.

He could use their every features as well by integrating them with himself, or just select one or a few of them.

He was excited.

Sena Sitri was really really excited at the moment!

He wanted to dance like crazy to celebrate it, but hold himself back, and calmed himself down.

Looking at the ten figures with satisfaction, he nodded and waved his hand, dispelled them, turned them into pools of water on the ground.

Looking at the ice statue of frozen Berserker again, he wondered what to do with it, and decided to ignored it for now and continued with his next objective.

'One objective completed. To the another one.'

Strolled into the Mansion again, he frowned when his sight landed on the frozen worms on the ground.

'Yuck! Disgusting! What kind of worms are those...'

He scrunched up his nose in disgust, and unfolded his wings to fly instead of walk.

Flew into the Mansion, he wasted no time and went to where his next objective was.

Thanks to the Frost Mist still covered the area inside and outside, he had a perfect view of the whole place and knew where she was.

Soon he reached a room and destroyed the door with a water whip.

As he entered, he could see there, laying on the bed, frozen, his next objective. Tousaka Sakura, or Matou Sakura as of now.

She was sleeping, it seemed, when Sena used the Ice Age.

She was frozen by Sena's Ice Age as well, and Sena did that intentionally, to put her in a comatose state, along with whatever bug the sick old man put inside her, if there was any.

Before Sena froze them, he made sure before hand that it would only put them in a comatose state. Mostly because he didn't know the exact thing Zouken did to Sakura, and didn't want to make a rash move, like killed the old man and inderectly killed Sakura as well.

So he chose to froze everyone and everything first, kept them alive, then cure Sakura, from anything that could possibly endanger her life, after that.

With Sakura secured, he could move more freely later after.

Slowly, he approached the frozen little girl, and as he stood beside her, could not help but frowned a bit, as he remembered about how disgusting the frozen worms he saw at the entrance.

'And this girl actually...'

The scene he saw in the anime then resurfaced in his mind, made him had a goosebump.

They were a creepy-crawly enough to watch in the anime, and earlier, he saw the real-life version of them... And this little girl actually thrown into an underground, to be...

'No no no! Don't imagine that! Don't imagine that!'

He shook his head and pulled himself together.

Took a deep breath, he relaxed his nerves.

He then looked at the little girl, reached out his right hand, and from his hand, a water stream, glowing blue in color, surged and enveloped her.

All-cure Water.

An ability he created with AWE specially for her.

This water had properties to cure someone from anything, even a curse.

He knew little about the things the old man did to her, that was why he created it as comprehensive as possible and as potent as possible. So no matter what threatened her, this ability could handle all of them.

Because of that though, in exchange for it, the ability consumed ridiculous amount of mana to use. Like, really really ridiculous.

His other abilities consumed so much mana as well, but this All-cure Water was on another level.

It was many times mana-consuming than his other abilities.

But fortunately it was worth it.

As the more mana he poured, the more potent the water would become.

And with Insta Recovery, this mana consumption was nothing. It could keep up with it just fine, and effortlessly at that.

Why did Sena bothered himself rescuing her?

Honestly? It was simply because she was one of his waifus, no more, no less.

His dick had a much say in it, sure, but it couldn't be helped.

She was his waifu, so he would naturally had an emphaty for her.

Knowing that his waifu was in a horrible situation, while he had the power and strength to save her, he would naturally try to save her.

Though she was still a little kid and far away, outside of his strike zone at the moment, in fifteen years or so, she would.

'A pity that I was summoned in this war and not the next one, I don't need to wait too long to meet them otherwise...'

He lamented as he thought about his other waifus in this world, Rin and the "ohohoho blonde drill" in particular, and couldn't help but sighed when the fact about their age came to him.

'I'm not a pedo...' He thought and shook his head.

He readjusted his mind again and put his attention to the little girl before him.

As the water enveloped her, he started the process immediately, and the water glowed brighter and brighter as it started to cure her of anything harmful for her.

Sena also melted the ice, which froze her, at the same time, and poured his mana more into the curing process.

It took only a few seconds to cure her as the glow the water gave started to dim bit by bit.

The glow finally gone after a while, and the process was ended.

Sena retracted the water back, as Sakura slowly opened her eyes, woken up from her sleep.

She blinked her eyes a few times, looked around, and stopped when her eyes met with a stranger eyes beside her.

Sena smiled a little when the little girl was staring at him in daze, thought that maybe she hadn't fully awake yet.

He had no thought, not in the slightest, that the little girl was in daze because of his good look.

Like, c'mon! How old was she? Probably around five or six. It was impossible to a little girl at that age to know something like that, right?

So he just stood there, waiting for her to fully awake, and smiled as amiable as possible to show her that he was here not to harm her.

Sakura slowly sat on her bed, still looking at Sena, then asked him.

"Who might you be?" She asked Sena softly and politely.

'So polite. She's cute.' Sena thought.

'But...'

Sena reached out his hand, and patted her head.

He realized that her eyes contain emptiness, something a little girl her age shouldn't had.

But looking back...

He put the thought back, and smiled at her again.

"Nice to meet you, Sakura. My Name is Sena.

And I'm here to save you." He said that very softly, but audible enough to make sure she heard what he said.

She was startled hearing that.

Many emotions swirling inside her heart.

While suspicion dominate them, considering she heard that from a stranger, her suffering and desperation pulled desperately the tiny hope sank far away deep inside her heart.

Kariya's face then resurfaced inside her mind, someone who also gave her the same hope, and how bad his condition had become because of that, and kept worsening as time passed.

A result he got as he tried to oppose Zouken.

That thought wavered her tiny little hope, shook the eyes which staring at Sena, noticeable enough to be noticed by him.

"Save me?" She opened her mouth timidly, and even Sena could tell that there was a fear in her voice.

What or who she was afraid of?

"You don't need to worry about Zouken." He said lightly, and as expected, got a reaction from her.

He chuckled and rubbed her head softly.

"Zouken... I took care of him. He and his worms... will never be able to do anything to you again. I cured you as well... and took care the worms inside of you... It's alright now, Sakura. You're save... You are save."

Sena told her slowly, so that she could understand everything what he said to her.

A stare was the response he got.

He could tell clearly that she wanted to believe him, but afraid to believe him as well. He was a stranger after all.

She was confused, and Sena could understand that.

So he stopped rubbing her head and straightened up.

"We could talk about the rest later. For now, let's find Kariya and save him as well."

Sena said as he offered his hand.

Hearing about Kariya's name, She looked at his smiling face, at his offered hand, and looked at him again.

She was hesitating, and Sena let her took her time and wait silently.

After a while, Sakura looked at the hand again, and timidly took it.

He helped her got out of the bed and went outside hand in hand.

Along the way, they said nothing, but Sakura's eyes couldn't help but wandered around, looking at the frozen surrounding.

"I did this.... I froze the whole Mansion... Zouken, and the other inhabitants, even the worms, I froze them as well..." He said lightly at her after glanced at how she looked at the frozen things they passed.

Hearing what he said, Sakura looked at him. Her eyes enlarged, as amazement and fear could be seen from it.

Then she catched something from his words.

Zouken... and his worms were frozen.

Was that true...

Her thought was interrupted though, as they stopped before a door.

It was frozen as well.

Sena then touched the door, and as if it never there before, the ice covered the door disappeared.

Sena opened the door and the both of them entered the room.

Inside, Sakura could see two standing figures, frozen inside of a block of ice each, to her surprise.

One was Zouken, and another one was Kariya.

She was... glad and happy when her eyes catched the sight of the frozen state of Zouken.

But become worried when she looked at Kariya.

"Uncle Kariya..."

Sena told Sakura to stay back a bit as he approached Kariya.

Sena would cure Kariya as well.

He enveloped him in the All-cure Water, and released him from his frozen state.

He was awake when Sena froze him, so when he was unfroze, he was awake immediately, flailing desperately when he found himself drowned and tried to escape.

He gave up his attempt though when he realized that he could breath, even though he was 'drowning'.

'What happened!' He thought.

But then the water around him disappeared and he fell down on the floor.

He stayed on the floor for a while, gasping for air greedily.

He looked up after that an found a pair of purple eyes looking back at him.

"You alright?" Sena asked him amiably with a smile.

Kariya said nothing and only looked at him in silence.

He then registered Sena's appearance, fell back and backpedaled desperately, trying to distance himself from Sena as far as possible.

Kariya recognized him!

The man who stood before him was dangerous!

He captured Berserker and froze him into an ice statue before he could make any retaliation!

Anything that made contact with the mist he created would be frozen as well! Just like the bugs sent by Zouken were.

'Right! Berserker!'

He failed to summon him back before, trying to free him from his frozen state with a Command Spell, wasted one of the three Commands Spells.

'But if I use all of them!'

Controlling Berserker would be very difficult if he used up all of them. But he had no other choice!

He looked at the forearm where the Command Spells was, and stunned.

Wide-eyed, he glared at his forearm.

But no matter how hard he looked, the Command Spells was not there!

It was gone.

His mind was blank at first, then in chaos and turmoil.

His chance to save Sakura!

To oppose Tokiomi!!!

To... Aoi!!!

He tore his attention from his forearm to the man stood before him.

Kariya glared at him. At Sena.

It had to be his doing!

And his guess was correct as Sena raised his hand and showing his forearm.

"Looking for this?" Sena asked with a chuckle.

His Command Spells was really there!

He stole it!

Before Kariya said anything, though, Sena said again,

"I think you don't need it anymore..."

Sena glanced at his side, and Kariya did the same.

He looked to the side and his eyes enlarged in disbelief.

He could see there, Zouken, frozen inside an ice block!

'Is he dead?' Kariya thought, forgot about the fact that he himself, was in the same situation until a few moments ago.

"And you don't need to be worried about Sakura, She's fine." Sena added, grabbed Kariya's attention immediately as Sakura's name was mentioned.

Sena step aside and pointed at her behind his back. He stepped far enough so Kariya wouldn't had any obstruction to approach her.

"Sakura!" He exclaimed in surprise of her presence in this situation.

Being cautious of Sena, Kariya glared at him who stepped to the side, shrugged and rose both of his hand as non aggression gesture.

Even with all the gesture, he still cautious. But his worry over her, win him over as he darted towards her in hurry.

"Sakura, why are you here? Are you alright?" Checking her condition, he asked in worry.

"She is fine. I cured her of the worms that infested her body." Sena answered the questions in her stead with a harmless smile.

Sena's answer reminded Kariya of his presence, as he turned his attention towards him, took Sakura to the back and shield her with his body.

"And For Your Information, I cured you from the worms infested your body as well, you're welcome! Watching you could run just fine instead of limping, I think you are fine." Sena said again, and what he said startled Kariya.

Cured him?

He registered what Sena said, and a realization cleared his mind.

Right!

He was running a moment ago!

He looked at the both of his hands with amazement as he could feel his body was in a perfect condition.

This feeling was the state of his body before the nightmare started!

He reminded by what happened and looked at Zouken, who was frozen, then looked at Sena again, with less hostility, but still with cautiousness and suspicion.

"Who are you? What do you want from us?" Kariya asked cautiously.

The man in front of him was strong!

Stronger than Zouken. And considering how he incapacitated Berserker in a short time before he could do anything, it was highly likely that he was a servant, and one who was stronger than Berserker!

The situation was frustratingly bad.

They were completely under his mercy now.

The situation was really bad for them!

"Of course you will be suspicious of me. Understandable. I don't mind that either. Let's we started with introduction."

Sena smiled to them and introduce himself.

"My name is Sena Sitri. A pleasure to meet the both of you."

He bowed elegantly, introduce himself with class and grace of a noble he was.

"As for what I want from you..." He straightened his posture and trailed with two fingers pinching his chin.

"Believe or not is up to you, I don't care. But I came here to save Sakura from the torture she was subjected into. Save you as well, because you are the only one I could entrusted her with and take care of her, in a chance that Tokiomi being a dick and refuse to accept her back."

"To make no complications whatsoever afterward," Sena added and glanced at the frozen figure, "I will kill Zouken as well." He declared, to their... relieve and delight. Even for Kariya, who was Zouken's son.

"Oh right. I will take Berserker as well." He turned back to them, as he showed them the Command Spells which had two commands left.

"Just consider it as a payment. It would be dangerous as well for you anyway, who are not a mage, and without the worms, to become the master of a servant, and one like Berserker on top of that." Sena said and Kariya knew about that fact as well.

Without the worms, he would be struggled to just maintain the contract, let alone make Berserker fight or even use a noble phantasm. And with Berserker's nature taken into consideration, become the master of a servant like Berserker would be a suicidal move.

As Kariya thought about that, Sena decided to end everything and stepped to the frozen Zouken direction, pulled Kariya's attention again.

Stood before the block of ice that froze Zouken inside, Sena rose his hand, and out of it, stream of water came out and encased the block of ice, along with Zouken in it.

Looking at the scene, it would be a lie if they said that they didn't feel any fright. But Sakura and Kariya stay still there, silently watched whatever Sena tried to do with Zouken, wich from his words, was still alive, for now.

What did sena trying to do?

Sena was trying to extract his knowledge, especially the knowledge of the inner working of the Holly Grail War.

With Berserker in his possession, and looking at Zouken inside the block of ice, a memories of the Heavens Feel route resurfaced in his mind.

Using the fake assassin's body as catalyst, Zouken summoned the true assassin in the Heavens Feel route.

Sena was wondering, was it possible for him as well, using Berserker as catalyst to summon another Berserker.

If that was possible, would it be a random summon, like if someone did the Servant summoning without a catalyst, like Ryuunosuke. Or could he used another catalyst to get the servant he wanted?

That was why he wanted to extract Zouken's knowledge about magecraft in general, and about the inner workings of the Holly Grail War in particular.

He would acquired the disgusting part of the knowledge as well, sure. But he didn't mind.

He just had to clenched his jaw, and bore with it.

'The things I did for Raiko's bouncy tits and juicy butt!' He thought and let the Extraction Water did it's job.

Extraction process of the Extraction Water and the copy process of the Water Soldier would result the same thing if he used them now. He would get Zouken's knowledge no matter which one he used.

The difference between them would be he "steal" them and got the original with Extraction Water, while he would got the copy of it if he used the copy aspect of the Water Soldier ability.

Also, using Water Soldier ability would copy the whole thing, the whole template, because it was meant to be used for creating Water Soldier, but with Extraction Water, he could choose what he wanted to take and what he didn't.

And he simply didn't want Zouken as his Water Soldier.

Why?

Because his Water Soldier was like Shadow Clone in Naruto (or maybe water clone in this case?).

Even though they would had absolute loyalty to him, they would still had the personality of the original, as they are the perfect copy of them.

So, having a Water Soldier like Zouken around him....

Yeah... no.

Thank you very much.

Berserker Lancelot was fine.

He was mad, sure.

But Sena had his absolute loyalty, so controlling him was easy.

He was quiet as well, because... maybe as Berserker, Lancelot's vocabulary was only limited to "Arthur" and "Aaarrrgghhh"?

So yeah, the mad knight was tolerable.

And Sena was a bit picky about his Water Soldier.

Pulled himself from the distracting thought, he readjusted his mind and continued the process.

In the middle of the extraction process, Sena suddenly frowned as he found something... unusual, but he continued and it ended when the extracted knowledge stored in the AWE, in his mind space.

Yes. AWE existed deep inside of him. Inside the deepest part of his soul, in the form of water a droplet.

It had became an inseparable part of him after it fused with him.

Berserker template also stored there.

He had an intention to integrate with a few skills Berserker had after this. After all, Lancelot was a strong knight with a few useful skills, and now with Zouken's knowledge, he had a new thing to integrate.

The danger?

No, there was no danger in the integration process.

It would pretty much like using a class card of Illya's world. But permanently and he could choose what he wanted to integrate.

After all, he had absolute mastery over the Water Soldier ability.

It was fine.

As the extraction process ended and the knowledge stored inside him, he retracted his hand and the Extraction Water also receded back.

With both hands in his pocket, Sena looked at the old man frozen inside the block of ice.

Earlier, when he did the extraction process, he found that this geezer's soul was scattered around the places, puzzled him.

He needed an access to the mind of the old man after all to extract the knowledge, so it was necessary to find the source.

He followed the connection, and it lead him to many worms in the vicinity which he found contain the soul of the old man.

'So you follow the baldy Voldy's step, or what?' Sena remarked in his mind about the discovery.

That was his guess at first, but that didn't last long.

Because when he traced all of the connection further, he found that it was not the worms contained many parts of the old man's soul, like how Voldy split his soul and put them into items. But one of the worm underground, actually controlled all the other worms through some kinds of soul connection.

This souls he found in the worms was just some kinds of echo from this one particular worm.

And Sena bet his money, after further inspection, that this one particular worm was the one which where the main soul was contained. In other words, the main body of the old man.

This dude actually transferred his soul into a worm, and connected that one worm with many other worms through some kind of soul network, and controlled them remotely and make them his proxy, just like how Sena use his avatar while his main body holed up in the Isekai Truck.

This way, even if he killed the old man in front of him, if this one particular worm was survived, the old man would survived as well. Because this one worm was the real Zouken.

'For immortality, someone actually went this far... He actually changed himself into a worm...'

This old man was disgusting, but Sena couldn't help but amazed by him as well.

Fortunately though, all the worms which had the soul connection were frozen, the ones underground included, so this one worm, which was Zouken's main body, was frozen as well.

He triple checked the connection again, to make sure, and indeed, the worm which contained the soul were only this one and was frozen.

'Now that I think about it... I think I read somewhere that the old man indeed put his soul in his worm...' Sena jogged his memories and faintly remembered he read something about it somewhere.

Maybe fandom?

Or fanfiction?

He shrugged his shoulder.

'Doesn't matter.' He thought, as all the worms was frozen anyway, and put his attention to the matter at hand again.

Manipulating the block of ice that encased Zouken, Sena changed the properties from "put into comatose state", to "freeze to the very core of the soul".

He froze the old man to the death with that, and with a "crack" sound, he destroyed the block into pieces, then made the pieces crumbled into particles.

Nothing was left behind.

Everything reduced into particles.

He snapped his fingers, and did the same with the frozen worms as well.

Every single worms, which was Zouken's familiars, all of them was destroyed.

There was no chance for the old man to survive from this.

He turned around to say something to them, but then stopped.

'Wait! Oh shit! I killed Byakuya too!!!'

When he snapped his fingers, he forgot that Byakuya was still frozen among them as well!

He was too occupied by the thought of thoroughly eradicate the old man and his worms, forgetting this man among them.

'Well... Collateral damage happen...'

The guy was a shit as well anyway, for making Sakura's life difficult and actually helping Zouken to educate her.

The only one who was nice to her in this mansion was Kariya.

So Sena just shrugged his shoulder and let it pass.

"Zouken is dead. His worms were also no more." Sena said to them.

"My business here is over. I advise you to leave the city ASAP. But wait until I remove the water bubble, though, and you could make preparation in the meanwhile. I'll remove it tomorrow morning. It's dangerous to go outside in the dark with many servants around."

He turned around to leave, but Kariya stopped him.

"Wait! Why are you helping us!?"

He was suspicious of Sena, but the man, without a doubt, save them. He wanted to know the reason why he helped them from their desperate situation.

Looking at them, Sena thought about it for a moment, then looked at Sakura.

He gave her his most dashing smile, in his opinion, and said,

"Well... A beautiful girl was in distress, so of course I come to save her."

It was awfully cringe, he knew! So no need to remind him of that, thank you very much!!!

He also could faintly heard the sound of sirens in his head, but he ignored it!

'It's investment!' He convinced himself, even though he felt a pang, when a realization, that he was flirting a little girl, hit him hard.

But looking at how Sakura just stared at him, blankly as he couldn't see any particular emotion from it, he sighed inside and gave up.

'What did you expect from someone at her age? She is obviously clueless about that kind of thing!'

Reprimanding himself for his, 'in his opinion', failed attempt to make Sakura had some kind of childhood crush on him, he sighed in his mind and opened his palm.

Water swirled above his palm, shaped into something as it began to freeze. In no time, a beautiful pendant was made.

It almost transparent in appearance, because entirely made out of ice. The chain and the water molecul shape pendulum, all was made out of ice. But even so, the pendant didn't feel cold at all to the touch.

It had properties to absorb the energy in the air to store it, and used it to powered the features it had.

It would improve the wearer health, enhance recovery, always have good sleep, and protect them from any harm.

It had a curse though, to make anyone who wear it, other than Sakura, had a severe hypothermia.

Thanks to AWE, if it was water-related, Sena could do anything. Like, ANYTHING!

Thought about it, and he would know how to do it. With absolute mastery on top of that!

With Water Movement, Sena teleported the pendant around Sakura's neck.

"A parting gift. Make sure to never allow anyone except you to wear the pendant. If it wore by you, it would give you many benefits. But if anyone but you wore that, it would harm them instead."

Sena said to Sakura, still with a smile, who was startled by the pendant around her neck, which she suddenly wore.

"You better to pack up and get ready. Good bye."

Without waiting for the both of them to recover from their surprise of his sudden gesture, he said that to Kariya and disappeared, teleported to where Berserker was.

He then made the ice that froze the entire place disappeared, grabbed the chained and frozen Berserker, and teleported to where the Isekai Truck was.

He kept the water bubble encased the residence intact though, and would make it disappeare when it was safe for the both of them to travel around the city.

Meanwhile, inside the room, hearing what he said, the two pulled back from their surprised state and looked at Sena, or where he was supposed to be.

They wanted to say something, but couldn't as Sena was not there anymore.

Kariya then looked at the pendant on Sakura's neck with worry.

Kariya then kneeled to make himself a level with her, and grabbed her shoulders softly.

"Sakura, if you feel uncomfortable with the pendant, just take that off..." He said and rubbed Sakura's head reassuringly.

But Sakura shook her head, and to Kariya's surprise, smiled at him.

A smile that he never saw for a long time.

"It's alright, Uncle. It's feel comfortable and... warm." She said softly.

She dearly hold the pendant, looked at where Sena was before.

"Thank you." She then said with a smile, as a tear dropped from her eyes.

Looking at Sakura like that, Kariya smiled as well and hugged her.

He still couldn't fully throw away the suspicion he had for Sena, but he still grateful for his help.

He knew how bad his condition was.

Even if he survived the war, he would not live for long.

So he planned to give his everything to win the war, and save Sakura from Zouken's clutch no matter what!

Even if he would have a short life after that, as long as Sakura was save, he didn't mind.

But now, not only he survived, he was cured as well.

And he didn't need to participate in this absurd and nonsense magus ritual anymore to save Sakura.

As she was saved already.

'Thank you.' Kariya whispered in his heart.

'Thank you, Sena Sitri. Whoever you are.'

Kariya gave his thanks, from the deepest part of his heart.
