Terrorist Attack

Regina's PoV

Father is now explaining the current situation.

"We're under fire. In any era where a power tried to form peace with other powers, there will also be a gathering of those who dislike it and try to disturb it."

Father then pointed outside the window towards the magicians that came to attack.

"Those guys are so-called magicians. It's a kind of magic that was originally interpreted from the magic system of devils by the legendary magician "Merlin Ambrosius" and reconstructed as sorcery…From the power of the magic they're emitting, I'd guess that they each possess themagic power of a mid-class devil."

Among the different Mages in history King Solomon was the strongest, being able to use any kind of magic however it was Merlin Ambrosius who interpreted the magic of the Devils for human use. He derived it from the knowledge left behind by Solomon who studied different magic and contracted several demons along with his own research.

"In short, it means that humans can use powers like those of devils. Though, of course, it also seems to be possible that they can't become devils themselves. It's especially troublesome when a Sacred Gear possessor learns magic. Well, their attacks aren't capable of damaging this school building. Because the strongest protective barrier by me, Sirzechs, and Michael is enveloping this place. Though, thanks to that, we can't leave here."

"Most likely, they used a Sacred Gear or magic that transfers power on the half-vampire kid's Sacred Gear and forcefully made it go into Balance Breaker state. It's only a temporary Balance Breaker state, even then, to think that it even affects people present in the interior of objects outside the field of vision…So that half-vampire's potential ability was this high. Well, it seems that he lacks the output to stop us top-position guys, though."

This is gonna be troublesome...

"But, they transferred power? There are other Sacred Gears with that kind of ability?"

"Boosted Gear combines together both the nearly endless doubling ability and the transfer ability. There exist independent Sacred Gears with either of these respective powers. The doubling Sacred Gear and transfer Sacred Gear. All the Longinus are just a combination of one ability with another. Essentially, they combine powerful abilities that aren't supposed to be combined. "Maybe the [Longinus] are born because of a kind of bug, errors in the [Sacred Gear program] constructed by God", that's one of the opinions of us 'Grigori'. If I had to say it in an easy-to-understand way to you, it's a fact that there are other powers that can transfer."

"If its the boosting aspect there is a common sacred gear called [Twice Critical] that has a lesser version of your Boost. It was the sacred gear your Ex mistook your sacred gear for." I added which caused him to grimace remembering his encounter with Raynare.

My sacred gear, [Gate of Babylon] also has a lesser derived sacred gear. One of our comrades, Alyssa actually possess it. Its called [Dimensional Gate]. It has the unlimited storing aspect of my gate of babylon without the record. Of course it also cant fire weapons at fast speeds.

"Gasper has been made into a terrorist weapon at the old school building…Just where did they get information on my servant…Moreover,for them to use his power to go after this important meeting…! Never have I been so insulted like this!" Rias said in anger.

"By the way, the armies of the fallen angels, angels and devils outside of this school building all seem to be stopped as well. Geez, Rias Gremory's family is just dreadful."

"They are basically sitting ducks outside." I said with a sigh. I then turned to Father and asked.

"Me and Ilya will thin them out a bit."

Father nodded in agreement as he sent projections of light and eliminated some of them.

Me and Ilya then leaped through the window to go outside to confront the terrorists.

"[Gate open!]" Upon my commands countless golden ripples appeared outside and shot countless projectiles towards them.

"[Divine Forge Start!]" Ilya also fired her own blades towards the magicians outside.

The magicians seeing us also fired their own magics towards us.

"[Project : Aegis!]"

In response Ilya raised her left hand as a golden shield appears, blocking their magic.

The battle continued for a while which shows no ending. More and more magicians appeared and attacked us.

"This will be troublesome with their numbers." Ilya said as she continues to fire some weapons blades of her own.

"I'll see what Father and the others are planning. Will you be alright here?" I ask her, while firing myown blades.

"Yes, it wont be that difficult unless the big shots come. Which will probably happen soon. Be careful."

"You as well, I'll be back soon."

I nodded and went back inside.

Going back inside I saw that they were discussing their plan.

"Im back. Whats the plan?" I asked Father.

"They are planning to use castling to save their friend and potentially stop this time barrier to allow our forces to move." Replied Father.

I then look over to them who is continuing their own discussions.

"Alright. However, it's reckless to go alone. Grayfia, is it possible to transfer more than one person through [Castling] with my magic system?"

"Yes, it seems we can only deploy a simple technique ceremony here, but it's possible to transfer ojou-sama and one other."

"So Rias and someone else…"

"Sirzechs-sama, I'll also go!"

"Its dangerous with just the two of them." I said.

"Yes, however we can only send two." Sirzechs told me.

"Wait for a moment." I replied before calling for Ilya.

Shortly, Ilya returned.

"Ilya can you assist Grayfia-san in modifying the spell to send more people with them?" I said as I continue to create golden ripples which fired weapons outside the barrier.

Ilya nodded and went towards the spell.

"If its Grayfia-san alone, It would be hard to send more than two people in this barrier however if Ilya helps it will be much easier."

"I see, thank you."

We then discussed for a bit and it was decided that Rias, Issei, Yuuto-kun and Xenovia will go.

Sirzechs then turned towards Father and asked.

"Azazel, according to a rumour, you've been researching how to freely handle Sacred Gears for a fixed time, right?"

"Yeah, that's true, but what about it?"

"Is it possible to control the Sekiryuutei?"

"..."

Father fell silent in response to Sirzechs' question. However, Father groped in his breast pocket and—.

"Oi, Sekiryuutei."

Father called out to Issei.

"I-I'm Hyoudou Issei!"

"Then, Hyoudou Issei. Take this."

Father then threw something at Issei. Who caught it.

What Father passed were some bracelets that can are shaped like a ring. Multiple layers of strange characters were carved into them.

As Issei was looking at it doubtfully, Father explained their purpose.

"Those are bracelets with the power to control a Sacred Gear to some degree. If you find the aforementioned half-vampire, put one on him. It'll help him control his power somewhat."

"But, there are two of them…?" Issei asked confused.

"The other one is for you. You haven't mastered the power of the [Welsh Dragon], right? If so, put it on. If it's for a short time, it'll be possible to go into the Balance Breaker state without paying any price. This will be used in place of the price."

Thats pretty amazing actually. Although l dont need it since I can do balance breaker, that is still really powerful and convenient.

"As a side effect, you'll also temporarily undo the seal that's been applied on you. Your [pawn] power has been blocked, right?"

Issei hearing that looked shocked as he didnt expect Father to know of it.

Well its not that hard to deduce seeing Rias' power and the value of the Red Dragon Emperor. The stronger the [King] is the less pieces will be needed to reincarnate someone into their peerage. Of course the more pieces they have the stronger the boosts. However if Rias was stronger when she reincarnated Issei, it would have needed less pieces than what she used.

"This is only my personal opinion, but in terms of piece distribution, Ddraig is seven and you're one, right? No, it may be 7.9 and 0.1. [Promotion] also builds the necessary foundation for the sake of manifesting Ddraig's truepower. Either way, it's a fact that releasing Ddraig's power will release the seal as well, right, Rias Gremory?"

Rias narrowed her eyes and kept silent due to how Father was able to deduce that far.

"Use that ring as a last resort. Since it can't regulate its consumption of stamina, you'll just exhaust yourself wastefully if you activate it suddenly. It will consume an intense amount of stamina and magical power while in [armour]-equipped mode."

Father explained with a serious expression to Issei who is attentively listening.

"Remember this well. The current you is a devil that was originally born as a human. Even if one possesses a powerful Sacred Gear, there's nomeaning if the host is useless. If the opponent against the current you is inexperienced, you can just sprinkle Ddraig's power to win, but it's won't be effective to those with greater power and those who understand your ability. At any rate, you yourself are your Sacred Gear's weak point. —The cluster of your weakness is assuredly your inability to master it. You'll eventually die if you can't tame your power."

After that explaination we sent Rias and her peerage using castling. Ilya immediately returned to fight outside as Father turned to Onii-chan.

"Vali, go help Ilya outside. The fighting will disturb their plan a little."

"Sure."

He then turned towards outside and said.

"Lets go Albion! Balance Break!"

[Vanishing Dragon Balance Breaker!!!!!!!!]

Onii-chan then left to go outside the window.

"Azazel, Continuing the talk from before."

Sirzechs then approached Father.

"What are you trying to do by collecting Sacred Gears? You've been collecting [Longinus] owners too, right? Do you intend to kill God even though God no longer exists?"

"Its to prepare."

"Prepare for what?"

"Prepare? That's some uneasiness-inciting talk, even though you reject war."

Michael  said this in amazement.

"I said so, right? I won't go to war against you people. I also won't make war here. —However, means of self-defence are necessary. Rather,should I say we're not just preparing for an attack from you?"

"Then?"

"—The [Khaos Brigade]."

"…Khaos, Brigade?"

It seems like they didnt know of the organization's existence. Judging fron their furrowed brows.

"I only confirmed the organisation's name and background recently, but my Vice Governor Shemhaza has also had his eye on this suspiciously acting group from before that. It's said that they're gathering dangerous members from all three big powers. Some Sacred Gear-possessing humans who have attained Balance Breaker also seem to be included. I've also confirmed a number of [Longinus] possessors among them."

"Their goal is?"

Michael asked that.

"Destruction and mayhem. It's that simple, you know? They don't like this world's peace. They're terrorists. Moreover they're ill-natured to the extreme."

"The organisation's leader is the powerful fiendish dragon besides the[Welsh Dragon] and [Vanishing Dragon]."

[—!]

Everyone besides me became speechless at Father's confession. Though I have already known about it before hand.

"…I see, so that person has moved. The [Uroboros Dragon] Ophis—. The dragon feared by God…The one who kept reigning over with the position of the strongest since the world began."

Sirzechs-sama also wore a grim expression.

Father then turned towards me.

"Your not going outside again?"

"Well it seems they are coming."

"So you have sensed them that quickly..." Sirzechs said also putting his attention towards the direction im facing.

[Yes, Ophis is the leader of the "Khaos Brigade".]

"They have come..."

I look at the people who came from the magic circle. Judging from the symbol on the magic circle. This one is from the house of Leviathan. The blood related one unlike Serafall who was appointed.

"How do you do, current Maou Sirzechs-dono?"

I then looked at the person who accompanied her.

"Its you-!" It was the masked person who attacked us in the church.

"Its been a while Queen of Heroes." The masked person says. This time however she didnt have a voice changer and I can identify her gender from her feminine voice. Her voice also seemed young.

"So you were with them..." I said with a cold voice.

Sirzechs then came over and looked at the woman who came with the mysterious girl.

"The one descended from the blood of the previous Leviathan. Katerea Leviathan. What is the meaning of this?"

"So it's a feud between the new and old Maou sides that has become full-scale. Devils are also difficult."

Father just smiled like it was someone else's problem.

"Katerea, is it okay to interpret those words literally?"

"Sirzechs, it's exactly as I said. We are also taking charge of this attack right now."

"—So it's a coup d'état, huh?"

The mysterious figure then turned to me and raised her demonic sword, pointing it towards me.

"Queen of Heroes, lets leave them to their business, shall we continue our fight from before?"

"Father, I'll go on ahead while you guys deal with her." I said while looking at the mysterious girl's challenge.

"Will you be alright?" Father asked with concern.

"Dont worry, I will be." I responded with confidence.

"Alright go." He then nodded seeing my confidence.

"Lets go!" I responded to the mysterious girl.

"Excellent." She then waved her sword to the ceiling shattering it as she flew upwards. Seeing this I leaped towards her and chased after her.

We then arrived at the open area near the gym. In the sky above I saw Ilya and onii-chan fighting the countless magicians.

"I guess I should introduce myself to you at least. My name is Yaegaki Shizuku."

"As a fellow swordsman Its only fair I introduce myself in kind. I am Regina Gilgamesh Arclight Azazel."

I then looked on the demonic sword in her hand. I have some idea as to which sword that is, or rather which Katana it is but I still need to confirm my suspicions during this fight.

"Well shall we begin?" As soon as those words dropped she dashed infront of me as I retrieved Solis Catastrophe from the treasury and blocked her.

The malevolent aura from her sword is different from most demonic swords I have seen its the same yet different. We then jumped back to get some distance from each other. As both the Flames of Solis Catastrophe and her Corrosive Poison are dangerous towards one another.

"Take this and perish, [Corrosion Scythe]."

Seeing the incoming attack I sent out a [Holy Line] in retaliation. The two attack collide as my holy line was cut apart.

I hurriedly dodged as she once more charges towards me. I shot some swords from the gate which she repelled using her katana.

Dashing forward I gathered holy power in my sword as I met her blade that is similarly covered in a malevolent aura.

The force pushed the two of us a distance apart as I noticed that the damage the Kusanagi does to the ground is terrifying.

"Poison... that is close to acid in nature..." I said with a grim tone.

[Regina be careful of being hit by her sword. That poison is one of the most terrifying ones I have seen!] Angelica's reminder echoed in my head.

"Angie, can you take care of supporting me through shooting the swords?" I asked her. Since I need to put more focus into dodging Shizuku's blade. One touch from that is deadly. I must not make any mistakes.

"Also Partner, Low level blades wont cut it. Prepare higher ranked ones."

[Understood. Be careful, Partner]

I then called out towards my opponent who is similarly being wary of the swords from the gate.

"If I am not mistaken, that katana in your hand is the Ame-no-Murakumo-no-Tsurugi from Japanese Mythology right?" I asked her.

"Yes, this is that divine blade which is one of Japan's three sacred treasures also known as the Kusanagi, It was the sword found inside the Evil Dragon Yamata no Orochi. Ironically as you might have already guessed its soul also dwells within it."

So it truly was a cursed sword... The poison of that evil dragon is terrifying and one of the deadliest.

"Well enough chit chat, Shall we go for round 2?" She said before gathering a malevolent aura once more.
