If my memories served me right the mc had black hair and glasses and later when he got his powers I think it turned white and he ditched the glasses (not tokyo ghoul) the main villian I believe was his love interests brother or it was someone the girl knew. I also belive that the main villian didnt choose to be the villian i think he got corrupted, he had very long when he was the villian in rhe end of the story. There was also a character that lived in space. That's all I can remember
