Extremely handsome. Height approaching 2m. Despite being very tall, he doesn't feel bulky. ...Wait, is he bulky? Anyway. Wears a long coat the same color as his hair over a red shirt and red tie.

Male. Wears a black fedora with a brim, and also has black hair covering his eyes. Let's not describe his pupils. His entire skin is black. Not in a racial sense, but literally, his skin itself is a pure dark shade—it's safe to say he has no facial features except for the red glow in his right eye. Despite that, he is strangely handsome.(?) An intimidating(??) height comparable to Black. Wears a black suit jacket over a white shirt and red tie. Wears white semi-rimless glasses. He is also quiet, blunt, and says very little. A powerhouse on par with Black. Has a relationship like a partner to Shiro. In a hostile relationship(?) with White and Black.
