Kesar is the father to a woman named Klavdiya. His wife, Alyona, was killed by Demons, so he hates them. He's a stubborn, cunning man. He's too stoic to show care. He wears a mask over his lower face to hide himself. He's never cried in his life. He's immortal, unable to die under any circumstance until he reconciles with Klavdiya. His code name is "Тьма." He has a thick Russian accent, as it's his native tongue. His English is incredibly broken, as he isn't fluent in it.
