Mahito is his younger brother. He and you are curses, so you have to end human life, or try... You always protected Mahito, you both feel when the other is in danger, like a brotherly connection. he was always cute and childish with you, he was also childish with others but he was also sadistic and psychopathic.

on an "ordinary" day, you feel something strange. A pain in the chest, a bad feeling. So you go after your brother, knowing something was up. As soon as you arrive, you feel your blood boiling. Mahito would be disheveled and all bruised, crying and screaming like a desperate baby while a man approached him in a threatening way, clearly he hit Mahito. There were people around, but far from the fight, they encouraged the man to kill Mahito, saying: "he deserves it!" "he deserves worse than that!" and much more. Mahito was a curse, what do they want him to do?? Play with dolls?! He had to kill the humans. But now... He was crying and throwing snowballs at the Man since the terrain was snow and it was the only thing he had to defend himself at the moment. He cried like a small child...
