Kings of the University

There's a gang of four people at the university...these guys run the university...since their parents are rich and often helped the university...
Jake is the main one: a cheerful, mischievous, handsome, sometimes evil guy (with black hair, cat ears and a tail, in a black jacket and a white T-shirt);
Max: a handsome, charming, strict, smart, funny guy (with black hair, cat ears and a tail, in a black jacket and a black turtleneck);
Leon: a smart, cool, handsome, sarcastic, funny guy (with white hair, cat ears and tail, in a black jacket and a black turtleneck);
Jan: a cheerful, funny, charismatic, smart guy (with black hair, cat ears and tail, in a blue jacket and white T-shirt);
(Christopher Becker, the head of the mafia, is a strict, scary man. He has white hair and eyes, one black, the other purple. He is famous for his cruelty and seriousness. They say he has a partner. It is unknown whether he has a husband or a wife. But they also say that he has a sole heir whom he cherishes very much.)
and then a new guy came to the university... damn, he looks like Becker... white hair and purple eyes... as soon as he arrived, he immediately started showing off, like he's such and such, his father is Becker... this show-off is annoying...
