Looking at Grayfia and Eiji, Euclid is crazy and green

[Let me remind you again.]

[Quest objective: Hide your identity, watch your older sister and Eiji Seiya shop until the end without doing anything to disturb them from 30 meters away.

Reward for completing the quest: Sacred Gear Longinus Replica - Canis Lykaon

Failure to complete the quest: The system will disconnect from you and find a new host. You will also permanently lose one kidney for not being able to complete small quests like this that make the system disappointed in you.]

"....."

Actually there is no need to remind him again, Euclid's memory is very good.

But this thing called the system reminded him again as if threatening him which annoyed him.

Even so he could only swallow his anger because even though he didn't fully believe in the system, the reward offered by the thing was quite tempting for him.

Sacred Gear Longinus, Canis Lykaon!

Although it was only a replica and not sure how powerful it was compared to the real thing, but seeing him unable to do anything to the thing that suddenly appeared out of thin air and said "You are the chosen one out of trillions of people in this universe", "With the help of the system, you can become the strongest existence that looks down on everyone as long as you diligently complete quests to get rewards from the system" made him feel special.

Of course, Euclid didn't fully believe in what the system said, but since the first quest it gave him was quite easy and he could use it to verify whether the system was deceiving him or not.

He didn't mind giving it a try even though what happened if he failed to complete the quest worried him.

It made him who was carried away by emotions to kill Eiji immediately calm down and swallowed.

"Isn't that too much? You're making me lose a kidney if I fail to complete this quest?"

Even though he was a devil, losing one kidney would definitely make him troubled like a human.

[That's precisely why. Isn't this quest easy? Why are you afraid of failing? I'm also using this to see if you're worthy of being my host or not. There's no way I'd give so many good things to people just like that. If my host is unable to complete a small quest like this, I'd rather go find a new host.]

"Who are you looking down on? I can complete this quest! Isn't it just watching Onee-san and that bastard shop until it's done?"

[Who previously lost his composure and wanted to jump out immediately?]

"Okay enough, stop talking. You see, I'm going to finish this quest and after that I hope you don't deceive me."

Euclid snorted, this thing called system was very toxic. Unfortunately he couldn't do anything to it, even his devil power couldn't affect it.

In the end he preferred to gamble and see if the system deceived him or not.

He continued to follow his sister and Eiji to the clothing department inside the supermarket and watched them from a distance.

But his composure was again shaken as Eiji dared to do such a thing to Grayfia!

He couldn't see him clearly because of the curtain, the two of them went inside the changing room together.

'Eiji Seiya! You bastard, what are you doing to Grayfia in there?!'

Euclid knew for other people this quest was actually easy, but for him, the damn system seemed to deliberately make a quest that could make him feel green.

He had to continue to restrain himself and keep watching while his older sister was probably being molested in the dressing room by Eiji Seiya!

"Pufft!"

With his perception, how could he not know Euclid's existence and what expression he was making behind his mouth mask?

Eiji couldn't help but laugh. Grayfia who was holding some clothes in her hands looked at him in confusion.

"Eiji-sama, what's so funny?"

He shook his head and said, "It's nothing. I just remembered something funny."

"Something funny?"

"Yes, I'm remembering a movie scene where a guy stalks the woman he likes on a date with someone and he can only watch as she walks into the dressing room with another guy."

"...."

Why does that situation sound familiar?

Isn't that...

Grayfia looked at Eiji suspiciously, but the man said something that made her embarrassed.

"It's about time. Grayfia, try on those clothes."

"Wh-What? Here? But you're still..."

"Is there a problem with me here? Don't waste time, quickly try on some of the clothes I picked out." Eiji narrowed his eyes coldly, the dressing room space was neither too big nor small. He stood at the entrance with Grayfia in front of him who had a blush on her face that lacked expression.

Grayfia knew something was wrong with her because she always felt excited at Eiji's cold gaze. But putting that aside, she stared at the few clothes in her hand that he had picked out for her and couldn't help saying "Pervert" in her heart.

All the clothes that Eiji had chosen for her, were all made of thin, tight material, and showed a lot of skin.

These were not ordinary clothes at all!

These were lewd outfits and some cosplays like female nurse, female cop, bunny girl. Then there are also some sexy babydoll variants in white, red and black.

All these outfits are made for women who want to satisfy men in bed.

Grayfia was silent for a moment as she stared at the clothes in her hands.

A little hesitant, but saw Eiji's cold gaze that seemed to urge her. Grayfia made a decision, with shame, excitement, and a feeling of humiliation that a woman like her was actually treated like a maid who satisfied her master.

Over the years, being a maid was actually just a hobby. During her marriage to Sirzechs, despite being a maid and wife, she had never been treated like this.

Sirzechs never forced her to wear lewd clothes, only she sometimes took the initiative. But Eiji was different, he actually forced her to wear lewd clothes and that was in a place like the dressing room of a supermarket!

This man is so wild!

But instead of hating him, Grayfia liked him even more.

Under his cold and hot gaze, she unbuttoned her maid uniform one by one.

After the maid's uniform along with her skirt lay on the floor, Eiji could now see what was underneath that french maid uniform after a long time.

Black and white.

Eiji doubted whether Sirzechs was really willing to give a woman this hot to him? Did the red-haired man have a conspiracy?

Grayfia's figure wearing only black underwear was absolutely explosive and capable of destroying the country! It was so sexy, especially with her snow-white skin, D-Cup breasts, slender waist yet containing some muscles that instead of detracting from her beauty, actually made her figure look trained.

To earn the title of "Strongest Queen" and to have survived many wars in the past, Grayfia must have undergone physical training that could make her figure that good.

The big, round ass he saw from the reflection of the dressing room mirror didn't help either, it made Eiji's throat rather dry and thirsty to slap her ass when they played from behind later.

Don't know how it felt, but now was not the time to do that.

It was still in the supermarket and there was Euclid, a siscon who now had a green face as he stared at the dressing room they entered.

"....." Grayfia looked at Eiji who was looking at her figure without blinking, she smiled slightly and felt proud of her figure.

"What? Why are you silent? Hurry up and try on the clothes." Eiji scolded the woman.

Grayfia pursed her lips slightly and said, "Yes Eiji-sama, as you wish."

However, when she tried on the female police uniform for the first time. Eiji went even wilder, he told her to take off his belt and use her mouth to give him service.

As a good maid, Grayfia had no other choice but to do as he said under his domination which she enjoyed, she knelt down and let the man's big hands grab her hair in the process.

On the other side.

Euclid was almost crazy, his eyes red and his expression slightly distorted.

"Damn! Damn! Eiji, you devil!"

[Host, aren't you also a devil? Devil in the true sense?]

"Shut up! Is this still not enough? I suspect you're deceiving me. You really just want to see me feel humiliated and angry seeing my sister being molested by Eiji, right?"

He stood behind the clothes rack, if not for still caring about the authenticity of the system, he wanted to break the clothes rack in front of him and blow up the supermarket with his devil power.

From his vantage point and the lighting in the supermarket, even from a distance he could see a slight shadow behind the curtain. There were some clothes thrown on the floor, and the shadows of the two overlapping looked ambiguous.

Euclid felt his heart throbbing, not from pain but a strange feeling that left him dazed.

What was this feeling?

[Be patient host, you have to wait for them to finish shopping to complete the quest.]

You still want me to be patient in this situation?

"Eiji-sama, you want to buy all those clothes for me?"

"Of course. All those sexy clothes are for you to wear whenever you serve me at night."

"E-Eiji sama, don't say that too loudly. People will hear it."

Pufft!

This was the first time Euclid vomited blood because of what he saw and heard. He saw Eiji and his older sister already coming out of the dressing room. Eiji still looked the same, Grayfia was also wearing her maid outfit, but the difference was that the woman's silver hair looked disheveled.

His sister's cold face was gone, and this was the first time Euclid saw his sister's flushed and excited expression.

And such an expression was not shown on him, but on another man like Eiji Seiya!

Ah! From their conversation as well, it was clear that the two had indeed done something lewd inside the dressing room.

Perhaps it was because it was the first time Euclid saw his older sister like this with another man because usually when she was still with Sirzechs, he was always hiding in the Khaos Bridge headquarters and could still hold back the green feelings in his heart.

But now it was different, because of being forced by the system, he really had to endure the green feelings pressing on his head. He also had to endure the feelings of anger and jealousy when he saw his older sister who was practically his obsession for many years being molested by another man.

These painful feelings, even for a pureblood devil as strong as Euclid, he seemed to be prone to mental attacks and could not help vomiting blood at the sight in front of him.

Fortunately it wasn't enough to make him faint, so he could still follow the two, but he was also mentally tormented seeing Eiji holding Grayfia's ass from behind as the two walked out of the supermarket together.

Grayfia's face also had no resistance, she just looked embarrassed as Eiji's dirty hands caressed her ass in front of her eyes and several people in the supermarket.

Euclid felt like going crazy, he really couldn't wait to cut off Eiji's hand and kill him.

"Finally! Is it over already? They're done shopping! System, reward me right now, otherwise..."

[Otherwise what? You can't do anything to me.]

"....."

The system's voice that sounded mocking with a male voice didn't help either, in addition to feeling disgusted that the male voice was heard inside his head, even the normally calm Euclid wanted to explode because of this toxic system!

But it was true that he couldn't do anything to the other party, so he could only take it out on Eiji later.

[Ding! Congratulations host, you successfully completed the quest by following your older sister and Eiji Seiya shopping to the end without disturbing the two.]

[You managed to hold back the green feeling of seeing the older sister you love being molested by another man. Hahaha! Oh my... You really did it.]

"...Damn system, what are you saying?" Euclid took a breath and stared coldly at the golden screen floating before his eyes.

His blood pressure rising, he really wanted to defeat the man called the system if he could do so.

[Cough, don't stare at the system interface like that. You should be more patient, patient people are the ones who usually live longer.]

"Stop saying nonsense, quickly give me my reward! Hey you really tricked me, right?"

[I didn't tricked you. Since you've completed your first quest, the system recognizes you as its official host from now on.]

[The reward has been transferred! Congratulations host, you got the "Sacred Gear Replica of Longinus - Canis Lykaon". It's the same item as the one in your world, but it's been modified by the system, you should be happy!]

For the time being Euclid didn't care about the annoying words of the system, he looked around, and he didn't see the Sacred Gear that he knew Canis Lykaon should be in the form of a giant black dog with extremely strong power as one of Longinus.

With the addition of Canis Lykaon, he was even more confident to kill Eiji Seiya!

However, where was the big dog?

"System, you--"

[Didn't I tell you it was modified?]

"So where is it?"

[It's inside you, host.]

"Huh? What do you mean?" Euclid was confused, he tried to examine himself and exerted his devil power to try to activate something he vaguely sensed.

At that moment.

*Pop*

Euclid didn't know what was happening to him, right now he felt very small. The parking lot in front of his eyes became bigger in his eyes and he felt like he was standing on the ground with four legs.

"What, what, what's going on?! System, you tricked me!"

[Please calm down host, I'm not tricking you. Didn't you feel that while in that form, you became stronger and had abilities that Canis Lykaon should have?]

"I felt it, but f**k! What modifications did you make? You made Canis Lykaon turn its own user into a dog?!"

Euclid now really felt like he was going to faint, he looked at himself, and it seemed that instead of being a giant black dog.

He became a cute little black dog!

He panicked and tried to deactivate his Sacred Gear, but strangely he couldn't.

Before he yelled at the system again, the other party immediately said:

[I forgot to tell you. With greater power, there is a price you must pay. Don't underestimate your cute and small appearance as a dog, your dog punch is very powerful, but after use, you can only deactivate it after 24 hours!]

"What?! So I have to be like this for 24 hours? System, you bastard!"

Euclid shouted angrily, but from the other person's perspective, there was a small black dog with blue eyes barking while staring at empty air.

People passing by on the street thought the dog was cute.

Euclid felt humiliated, but this proved that the system was real even though he felt that the rewards it gave were playing tricks on him.

Feeling the power within him that was at least ten times stronger than he was in his devil form.

The power he felt right now was indeed real.

Although being a small dog seemed embarrassing, he was fine if he could kill Eiji with this form right now!

"Guk guk! (Eiji, I'll kill you and snatch Onee-san)"

[Haha! Oops. Cough, host. I suggest not trying to kill Eiji Seiya now. You still have to increase your power further, the current power is not enough to defeat him.]

Euclid couldn't believe that the power overflowing in his little dog's body right now wasn't enough to kill Eiji, he saw the man and his older sister walking towards one of the cars in the parking lot.

The little dog's eyes had killing intent, Eiji and Grayfia who were not ordinary people could of course feel that killing intent.

"Eiji-sama, that little dog... It looks like that dog is unusual." Grayfia said while pointing at the small black dog that glared at them without realizing that the dog was her younger brother whom she hadn't seen for a long time.

"Guk guk! (Onee-san, it's me, Euclid! Wait for me, I'll free you from Eiji Seiya!)"

"Hahahaha!" Eiji laughed while holding his stomach.

Euclid who approached step by step growled seeing Eiji laughing at him.

Stupid human, he didn't know his death was imminent.

Hearing Grayfia didn't seem to recognize him, he was sad but it made sense since he was still in this form!

"Eiji-sama?" Grayfia looked at Eiji in confusion.

Isn't it too much to laugh so hard at the sight of a dog? But this little dog was really unusual, right? Grayfia could feel that the dog had enmity with Eiji and the oppression she felt from the animal was very strong!

A supernatural animal? It seems so.

She stood in front of Eiji, preparing to fire her ice magic as the dog clearly had ill intentions towards her master.

It just so happened that the dog was also very fast, and he lunged at Eiji!

"Guk! (Eiji Seiya, die!)"

Grayfia's pupils shrank, her eyes she couldn't keep up with the speed of the little dog, she wouldn't have time to block his attack.

But at this moment...

[There's no need to be too serious. It's just someone with Sacred Gear who can turn him into a dog. I don't know why this person has enmity with me, but the origin emanating from him is somewhat similar to Grayfia's...]

"Boom!"

Eiji casually slapped Euclid who was about to attack him and the dog's figure was thrown across the city sky, even across the neighboring country.

After a while passed, there was no sign of the dog returning which proved that the matter was over.

Euclid actually passed out with just one slap in his dog form and now he was buried under the snow of Mount Everest.

Grayfia who saw this breathed a sigh of relief, she was glad that Eiji was fine and it seemed like it was just a minor problem.

But who was the person with the Sacred Gear who could turn himself into that dog? What made her most curious was...

Eiji said that person's origin was similar to her? What does that mean?

"The small matter has been settled. Let's go home." Eiji said, he didn't say that the dog was Euclid, Grayfia's younger brother, he just gave a little hint.

Although it would be exciting to see the drama of Grayfia who was surprised to find out that her younger brother was trying to attack him with murderous intent.

Now was not the time.

As for why not kill Euclid right away? Wait a minute, that guy had a system he made for him, it would be a waste if he didn't play him and utilize him a few times in the future.

¶{So basically you just want to give him the green hat a few times, right? Not worried about that guy doing anything bad?}

'My Sub-System is on him. In your opinion, with my current power, how can that little ant make waves? I'm not denying, I'm interested in seeing Grayfia and her brother hurt each other.'

'Ah, that should be fun.'

Miss System was not surprised, her host was indeed a person with a bad hobby like this.

Actually the reason Eiji followed Grayfia shopping was because he knew Euclid was planning to meet the woman after a long time and wanted to recruit him and Grayfia to Khaos Bridge on Rizevim's orders.

With "Future Sight", Eiji knew all that.

But before that happened, he prevented it by sending the Sub-System to play tricks on the man. 5000 system points were again spent from his wallet, but that was okay. It was worth it in the long run and he could also earn system points again every time he changed the plot.

"Yes, Eiji-sama."

The beautiful Grayfia didn't know the evil thing her master was planning, like a professional maid, she put the groceries into the car.

After that the two got into the car. On the way, while driving with the silver-haired woman sitting beside him.

Eiji glanced at the shape of the moon that gradually appeared in the sky.

It looks like there will be a full moon tonight.
