My favorite anime character is Kamui Kirito from Psycho Pass Season 2.
I like him because despite being the villian. He had enough charisma and character, to make me root for him.
It's not every day that I prefer the villians in an anime. I can count how many villians I'm a fan of.
Kamui Kirito made Psycho Pass suberb, so my vote goes to him.
