Kokushibo, Douma and Akaza

[On the inside, though, Doma is pure evil. He's a two-faced sadist and doesn't care about anyone. He was also clinically apathetic and couldn't feel emotions. He just tries to hide it by acting friendly.] [Kokushibo is quite reserved and silent. He often keeps to himself while retaining an aura of unnerving tranquility and mystery that adds to his personality as the topmost demon. He rarely speaks, but when he does, his emphatic tone gives him authority over his entire demeanor.] [Akaza is a stubborn, harsh, short-fused and bloodthirsty fighter who desires to fight the strong, respects the strong and loathes the weak.] Kokushibo, Douma and Akaza there from Demon Slayer anime.
