[Later]

Gin: YOU FRIGGIN STUPID IDIOTS, YOU'RE SAYING NOT ONLY DID YOU START SOMETHING WITH THE ACADEMY COPS BUT THEN YOU KILLED ONE TOO!?!?

He was currently scolding Kurumu, Tsukune and Gabriel, then he looked at Gabriel.

Gin: And you.. Why did you even killed Keito?! Couldn't you just make her unconscious? You know that they will surely use this thing against you?!

Gabriel: There's no fun on that.. And then, they are already here..

Everyone widened their eyes and turned towards the door, there stood silence for a moment before Gin turned to Gabriel thinking that he was joking, but the door opened to reveal Kuyou.

Kuyou: Indeed, we are already here.. Now I will ask this, give Gabriel Brace to us or even everyone else will be punished.

Moka: What did he do?!

Kuyou: He is the culprit of 5 deaths, 4 boys and Keito.

Gabriel: *Whistle* They already knew?

Kuyou: 'It was really him?! Wow, this is a lucky hit!' Come with us immediately.

Gabriel: Why should I?

Kuyou grinned and said.

Kuyou: I am really happy you chosen resistance, at least I can take down the club too..

Then he released his Youki in the area around them, making everyone back away of some steps except Gabriel.

Moka: 'What a strong supernatural energy.. But..'

Inner Moka: 'Yeah, it's nothing compared to that day..'

Inner Moka had some flashbacks about Gabriel's bloodlust against the slug, that was one of the moments where she really trembled, the first time it was when her own father fought with her, but that was because he had more power as a vampire and he was her father.

But Gabriel is not a vampire, even less her parent, so her pride would stop her fear of him, but it didn't happen, Moka puked and fainted, while Inner Moka, who was inside Moka's consciousness, felt real fear and despair upon looking at Gabriel.

Gabriel slowly got up from his chair and walked towards Kuyou while holding his hands in the pocket.

Kuyou: You know, I never encountered a King class monster.. Because they are pretty rare, and a teenager, is even more rare.. It just makes me want to burn everything!

Then he shot out hot flames everywhere, trying to hit Gabriel's friends.

But Gabriel just slammed his tail with much force in the ground, shooting the flames away from the gust of wind made from Gabriel's tail, making the people behind Gabriel raise an hand to cover their faces while Kuyou got surprised.

Kuyou: That is impressive, but it is normal for a King class mons- Oof!

He was interrupted when a strong kick hammered in his stomach, making Kuyou crash through several walls and spit saliva.

Behind him, everyone was shocked, especially Gin.

Gin: 'How is that possible?! Gabriel is in entirely another level! It must be a King class monster of at least an A rank.. If it is really like that, then it's obvious he could even beat vampires and werewolves..'

King Class monsters are completely separated from his own species, it is because of a really hard training that broke through the species' limit or for a mutation they received from their birth.

They can't be classified through normal means, for example, a Witch against a Vampire, Witches are A rank while Vampires are S rank, but if the witch is a King Class, then he or she could beat the Vampire.

There is even the King Class Shinso Vampire, Alucard, normally Shinso Vampires are beyond S class, but his strength is even stronger than his peers, and that gave him the power to overpower anyone thanks to his mutation that would let him get stronger by absorbing monsters.

King class monsters are really dangerous, especially those of A class or S class species, and right now, Kuyou was fighting one of the strongest monsters that are currently walking in the Japan, and probably the entire world.

Gabriel: What's the matter, Kuyou..

Then Gabriel transformed in his true form and a dangerous air came from him

Meanwhile, Kuyou felt the danger coming towards him and used his battle form as a Yoko.

Gabriel: ...You can't stand up anymore?

When Kuyou finished to transform, he tried to stand up from the floor, but he seen Gabriel ready to stomp him, and put his arms in front of him to block the hit.

When Gabriel stomped him, one arm broke while the other had some cracks in the bones, meanwhile the stomp destroyed the floor and made Kuyou fall in the other floor under him.

Gabriel: Hm? You aren't dead even after a slightly strong hit? That is good, I wanted to test my physical limits without Youki..

Everyone heard his words and were shocked.

Gin: He isn't using Youki?! That strength is crazy!

Tsukune: What is Youki?

Kurumu: It is every monster's inner energy, it permits the monsters to do many thing that otherwise they are too weak to do it, how do you not know it?

Tsukune panicked a bit but he immediately thought about an excuse.

Tsukune: Well.. I never used it..

Yukari: Still, how strong is Gabriel?! Being able to easily break a Yoko's arm while he is in battle form with just pure strength?! That is too much even for a vampire!

Meanwhile, at the lower floor, Gabriel was right at Kuyou's side, Gabriel was standing while Kuyou was in ground holding his broken arm in pain and gritting his teeth, then Gabriel thought about what would happen if he wasn't there, what pain could the club go through without him.

Gabriel: Kneel in front of me.

Kuyou's eyes widened, Gabriel was literally spitting on his pride as a Yoko, being seen as a god or the emissary of one from many people, and an insect type monster like Gabriel is asking him to kneel in front of him.

Kuyou: N-Never..

Gabriel used his nen combined with killing intent, and looked down at him, there was miasma-like energy coming out from Gabriel, which slowly covered the ground, and made Kuyou stop talking, the only sound that there was present was his heart beat, which was going crazy.

Gabriel: Don't make me repeat myself.

Kuyou could only whimper under Gabriel's stare, and slowly tried to stand up, he turned his body downwards and slowly pushed himself up, but before he could really stand up, a foot blocked him.

Gabriel put a foot over Kuyou's back before he could get up, making him seem like he's kneeling in front of Gabriel.

Gabriel: Now, it's meal time.

Kuyou's eyes widened and before he could say anything, a stinger pierced his head, killing him.

Then he took Kuyou's body in his shoulder and jumped in the floor over him through the hole he made, and met with the group.

Gabriel: I will go for a while, see ya later guys..

Everyone just watched dumbfounded Gabriel that was taking Kuyou's body away, probably to eat him.

[Later]

Gabriel just finished to eat Kuyou in a forest, and got a slight boost to his nen, proof of the strength of a Yoko, even if the boost was around the 4%, it is still a big one for someone like him, and surprisingly, he gained a new ability too..

Probably because the Yoko's meat was a really high quality, since they had the potential to be stronger than vampires with their number of tails.

Gabriel tried to use his new ability, but something strange was happening to his body, he slowly got 5 inches taller, his body developed armor-like black bones, which didn't limited either his agility and speed in the slightest.

He got small claws in his hands and feet, to be able to grab something with ease, or anchor himself in the ground. his shell-like armor over his head slowly disappeared and were replaced with dark green hair, which were the same of his human form except for the color.

The tail didn't changed much, except that now it could be retracted inside his body like Perfect Cell's tail, his antennas slowly disappeared, even if his skin color and the rest remained like it was before.

But the most big change is his own nen that was concentrated in his body like a combination of Ten and Ren, his aura was raging around, but not even a single bit leaked out.

Gabriel looked at himself with surprise, he seemed like a fusion between an evolved form of Meruem and himself in human form, but his own nen and physical prowess boosted of a really big margin, he didn't knew about his nen, but his physical prowess got at least 3 times stronger.

Gabriel: This is..

The ability he gained is the Battle Form which should be exclusively of the Yoko race, strengthening his body to another level, and like the name said, it is used exclusively for battles, and the best part of it? He got taller!

Then Gabriel tried to punch forward, and a simple punch of his in this form was half as strong as his punch when powered with Ko in his normal form, shocking Gabriel of his newfound strength.

Gabriel: Heh, this will be a new card to use against really strong monsters or other problems...
