He brought him in his lab, where he has a team, and they start experiment on Baby Iruma.

For 6 years, Iruma is experimented, his body is modified.

First they inject him a lot of mana, too much Mana. Iruma suffers of a high fever, and they force his tiny body to develop a mana system.

As soon it's done, they spent years to modify his adn. And inject him the adn of a Lion Demon. So little to little Iruma has horn in the shape of lion ears, followed by a lion tail. His teeths become sharp, his nails become tiny claws. Wings appear on his back after days of horrible suffering. He starts to hiss, to purr. He become agile, and he's always terrified by the scientifists.

Some other captives demon, also victims of experimentations, helps him, teach him to speak, to read, to write. He receives a minimal education thank to them, so he's not feral or totally illiterate.

Then he's saved by the Border Patrol when he's 10. At this point, he's now a 3/4 demon.

The 13 Crowns and the Great Three speak about what to do with Iruma and Sullivan propose to adopt him but Henry says that it would be better if it was a neutral person who adopt him. So no conflict of interest.

Banachi proposes the Marbas Family, because of their bloodine ability who could help. Sullivan proposes March, the new teacher. With his power he'll check the kid's health with his bloodline ability, and he could be helped by Murmur and Buer.

March (who is only in his first year as teacher) is now a young father of a 10 years old almost demon who is totally traumatized. He prepares the room next to his own. He creates a big comfy nest with a lot of soft blankets, pillows and plushies. He adds toys and books in the room. He knows Iruma has been mistreated, that he has never had his own space, that nobody never let him in peace.

So he has now a comfy room who can be his safe space.

A safe space JUST FOR HIM.

While Iruma discovers his new room, Balam comes. He wants to give some comfort to Iruma, because he loves giving affection to youngs demons. And this kids is SO nervous, his scent is so full of anxiety.

but what nobody know is that there had a gargoyle in the team of scientists and that this one was of the guys who hurted him the most.

Iruma sees this big gargoyle who is about to touch him and screams of fear, violently slashing Balam's arm with his tiny claws, then he hidde behind March, hissing and shaking of terror. Because all attempts at rebellion were always severely punished.

He's traumatized by A LOT of things, and is easly scared and triggered.

At first Iruma is very wild, but little to little, the teachers tame him with food and affection and gifts. And little to little he stops to hiss, to slash with his tiny claws. But he's still full of mistrust.

But he starts to trust the teachers, little to little (but he's still scared ob Balam and Kalego) (maybe Knightwalker was often in this lab too, and it's why he's scared of Kalego)

Marbas propose that Iruma meets Kerori (Kuromu) so he'll have friend of his age. And Kerori is shy and calm, she is perfect for a scared child as Iruma, she'll respect his limits. Mar and the Crocell Family are totally ok with it. Chima is sometime brought and she immediately adore this new big brother Iruma.

Then Marbas asks Shakky who is still student at Babyls if her little brother can play with Iruma (a traumatized kid who needs to socialize). Shakky is happy because her little brother doesn't have any friends.

Amaryllis proposes that Iruma plays with her darling son. Azz is enough calm to not scare Iruma (he quickly notice what make him uncomfortable or scared) and grows quickly affectionate toward him.

Then after theses three kids more or less calm and sweet, someone proposes the Valac Family.

Little to little Iruma becomes more and more happy, while being the most gentle demon ever.
