|Man with the Scar|
Episode 1 (Cameo)
The "Man with the Scar", or "Supervisor" is a major antagonist that is responsible for Jyugo's irremovable shackles. He has yet to be named. He is also the person in charge of Team Elf.
The front of his face has yet to be revealed, however, there are a few hints as to what it could be. In Jyugo's memories he is only shown to have a red scar that is horizontal with three evenly spaced vertical lines on it, as well as purple hair (though this may be a reflection of the light). Later, in Musashi and Noriko's memories, he is shown with white hair, which could indicate that it has been many years or that his hair is naturally white.
The personality is something yet to be revealed, since he has never appeared far enough to describe it and all the information on him is unknown to what extent and it is told by others, not by him. However, as seen how he leaves Musashi alone once he has done experimenting with him in the flashback, he seems to be an individual with little regard for life. Jyugo describes him as a "sadistic bastard" while Elf seems to respect him as he was angered by Jyugo's comment towards the man with the scar, although it is unknown to what extent this respect may be and how respectable it is.
Very little is known about his past. Aside from that he seems to have the ability to change people's body structure. However, he seems to have once been partners with Elf.
He makes a series of cameos within multiple characters' memories, but has never actually appeared thus far.
