Senbo

Senbo (羨望; Literally meaning Envy) is a several billion year old Sayo from the.

Appearance
Senbo is usually depicted as having black, long hair which falls down to his neck and having light green eyes with light green markings running down his eyes, giving the visual affect of tears. Senbo wears a large white helmet that covers half of his head. When he activates his Sin Seal, this helmet forms into two long horns ontop of his head, meaning it is most likely a natural formation on him. Senbo wears a white, high collar jacket over his bare chest. In the middle of his chest, Senbo has giant hole wear his soul was once ripped out by Usai Cipher in the process of becoming a member of the 9 Great Sins.

Personality
Let's just say, Senbo isn't really that upbeat or happy. Infact, he doesn't even seem angry or upset, he has little to no emotion on the outside. But on the inside, Senbo is a cruel and rude person, willing to kill anyone who gets in his way of reviving Hiradi Cipher.
