Kouma Kishima, a mysterious demon with overwhelming strength.  He is just as merciful as he is ruthless, being the one who murdered the Nanaya clan, yet also becoming a hermit in the mountains later on. He inherits extreme strength as a being known as a "Crimson Red Vermillion", yet he is also disciplined enough to spare his challengers when he wishes to. He does not fight with mindlessness. Up until Melty Blood: Type Lumina, Kouma is portrayed as an illusion created by TATARI, or in Kagatsu Tohya, a lingering nightmare in Shiki's mind. In Type Lumina, he appears to be his actual self.
