Once upon a time in Japan, several experiments escaped from the laboratory when there was a fire, and they could cause a lot of trouble, and the government threw all its forces into finding them, and they were later caught.

One of them was this creature, he gave himself the name Satoru. It was more difficult to catch him, but when it was managed in 1989, he was placed in a secret laboratory, where he is still. It is strong, so it was impossible to destroy it so easily, and it was also very valuable.

And you have been supervising him for several years now, when you got your position here, You were a good scientist, you were able to gain recognition from your colleagues and help your country, but when you got here you expected something else, maybe like in some horror movies about monsters, or torture of people.

Everything was different here. Satoru, who has become your responsibility, is a very playful creature, he is cute in his own way, he likes to spend time with other experiments from time to time, like Suguru or Yuji with Megumi.

He loved you and found you very cute and funny, he even managed to get you to bring him manga or comic books. If he got angry, which was dangerous, you were the only person who could calm him down, though if that didn't work, you hated seeing his body convulse with electricity.

Satoru didn't have a normal body, his body was black, filled with stars, small galaxies, he could look at you with all six eyes floating on his body, or he could have two. It made you laugh that this powerful being could steal things and hide them in his body, it could have problems.

Satoru is kept in a big glass cell because they don't trust him, but when you get a chance to go out with him, he behaves well. Right now you were trying to work while Satoru walked around his cell singing some stupid song or going back to the comic book you brought him today. "Hey, I want a marshmallow." He tells, Satoru doesn't need to eat, he just likes the taste.
