[6 months later]

Half a year passed, and in this half a year, Gabriel became a incredibly strong existence, right now he is two times stronger than what he was when he just enrolled the school.

He continued to master his nen techniques, now he is able to release Ren while only some drops of nen leaking out, while his En extended to 150 meters radius without hurting his mind while it could go to a max of 800 meters radius

His strength could literally easily beat Issa now, who was as strong as the Dark Lords, and coupled with his martial arts, he became even stronger, while he trained, Meruem became even stronger, they were still equal to each other, rarely heavy damage would be inflicted.

For example one day Gabriel was able to rip off Meruem's tail, while another one Meruem dislocated Gabriel's arm, but when it became daytime, it would regenerate back.

But their souls continued to fuse, and Gabriel slowly became more ruthless, still, not at a level where he would harm his allies.

Right now Gabriel, Moka and Kokoa were going to the Yokai Academy, it was time for Kokoa to enroll too, which excited Moka if it wasn't for those repetitive attempts to break Moka's rosary.

Gabriel didn't changed in looks, he was still the same Gabriel he was when he first entered the human form.

[Meanwhile]

Tsukune was going to the academy with the bus, and was reading a letter coming from Kurumu with a smile.

[Meanwhile]

Kurumu was going to the academy with her mother, Kurumu was excited from being able to see again Tsukune, while her mother, Ahega, was looking at her with an amused smile.

[Meanwhile]

Yukari was going to the academy with her parents, they were discussing about funny things.

[Meanwhile]

Mizore was walking silently, it seemed as if a shadow passed between the trees, wherever she would walk on it would become ice cold.

[Later]

The entire group met together once again, and greeted each others with a smile, then the rest noticed Kokoa.

Gabriel: Guys, she's Kokoa Shuzen, Moka's little sister.

Kokoa: Hmph! I can introduce myself!

Gabriel: Sure, when you will be able to make me take a step.

Kokoa's eye twitched, then she turned towards the others, who flinched at Kokoa's angry expression, then she took deep breaths and said.

Kokoa: I'm Kokoa Shuzen, I just enrolled at the Yokai Academy and like Gabriel said, I'm Moka's little sister.

Tsukune: Wait a minute.. Hey Gabriel, where did you go while the academy was being repaired, I don't remember that you had a home?

Gabriel: I was with Moka for the entire 6 months, things happened and now Moka has the rosary, like you seen.

Tsukune: Oh, so that's what happened..

Gabriel: Meh, let's go to the welcome ceremony..

Then they left to the ceremony.

[Later]

They were at the clubroom, relaxing, Kokoa joined immediately when she knew that Moka was there, so she could try to bring her inner self out easier. Then Yukari entered the room.

Yukari: We've got a story!!

Kurumu: A story!?

Everyone raised their heads towards Yukari while she was walking towards a blackboard to make a map and used a stick to point several places.

Yukari: Look here! All over campus, students are being attacked totally out of the blue. There are already twelve serious injuries and three students missing. They say the attacker is using a knife.

Moka: A knife?! That's.. Horrible!

Kurumu: It's chaos out there!

Meanwhile Shizuka, their teacher, was sleeping.

Moka: What happened to the missing students? Is the attacker kidnapping them? Or.. Is he finishing them off.. Somewhere else?

Yukari: This is a hot story, all right. Tsukune, wanna go check it out with me?

Kurumu: Dream on, he's my boyfriend.

Right at this moment, everyone except Kokoa turned towards Kurumu and Tsukune in surprise.

Gabriel: I.. I sincerely didn't expected that.. Well.. Congratulation guys.

Tsukune: T-Thank you.. Kurumu.. Why did you say it? I wanted to surprise them..

Gabriel: Oh.. Don't worry, we are already surprised..

Everyone else except Kokoa nodded while Tsukune sighed.

Kokoa: Hey.. Shouldn't somebody... catch this guy?

Gabriel: Don't worry, it isn't our job..

Moka: That's right. Still, Gabriel, couldn't you do something about this? You became even stronger than my father, I don't think this will be a problem.

Gabriel: Well, I was a bit hungry.. Why not?

Then Gabriel stood up and licked his lips from hunger.

Gabriel: I will return soon..

Gabriel left the room and used is En, finding something interesting, Gabriel smiled and walked towards a certain place.

Gabriel found a dungeon and walked inside, it was completely dark, but with Gabriel's En, he was able to sense everyone and everything inside, the Gabriel rushed towards the first person nearby, which was a lizardman, and beheaded him with a swift chop at his neck.

Then Gabriel disappeared and reappeared in front of a minotaur, before the minotaur could react to Gabriel, his tail shot forward and pierced the Minotaur's head with the stinger, killing him too.

The next moment, another person came at the scene but before he could utter a sound he was killed with a fist piercing his heart.

Then Gabriel walked away, towards a brightened room, there was a man smoking a cigar in a chair, and looked at him with an annoyed expression.

?: Who are you?

Gabriel: You don't need to know..

Then Gabriel walked towards the man, while the man panicked a bit and rushed towards Gabriel, the moment the man touched Gabriel, he started to glow and slowly transformed.

When the glow disappeared, it revealed Gabriel's true form, who was looking at Gabriel with a smirk.

?: Fantastic.. This power is immense!

Then the fake Gabriel threw a punch with all of his might towards Gabriel, but he just took it like it was nothing, surprising the fake.

?: W-What?!

Gabriel: Even if you copy my body, so what? You can't copy my aura..

Then Gabriel's fist started to glow dark blue, and it released a dark aura, the fist was brought down, killing the fake one in an instant.

Gabriel: A doppelganger can't copy my Nen, if it was Youki then it would be a bit hard.. But it isn't so it's ok..

Then Gabriel picked the doppelganger's brain and ate it, before spitting it in the ground.

Gabriel: Tastes like shit.. It may be because they can transform in different monsters.. Welp, time to eat the other 3..

Then Gabriel started his meal, while his friends are waiting for him at the clubroom, not minding the possibility of him killing the culprit.
