Kouma Kishima

Kishima Kouma (軋間 紅摩) is the man who eliminated the Nanaya clan under orders of Tohno Makihisa. He is a member of the Kishima clan, a clan which is a sub-family of the Tohnos but with much stronger demon blood running through them. When he was young, Kouma lost one of his eyes to Tohno Shiki's father, Nanaya Kiri. He is described as the perfect combination of human and demon blood, and possesses massive physical strength and speed, being able to crush trees with his bare hands. His nickname is Red Lion. He is a true Crimson Red Vermillion(紅赤朱), an existence far from human race. Nasu said in an interviw that he can fight with Servants on equal ground.

Kouma never felt the sensation of truly being alive until his death-match with Nanaya Kiri. Since Kiri was just a human, the outcome of the fight was decided from the beginning. But, because Kiri showed fierce resistance to the end and even caused serious wound on Kouma and made him feel pain for the first time in his life, the mixed-blood recognized the demon-hunter as being the embodiment of hell.

He spared the life of the yound Nanaya Shiki due having a feeling that the two would meet again in the future. Also, despite being something close to a monster with no human values, he voluntarily distance himself from human society and lives as an hermit in the mountains, something that Aozaki Aoko praised him for.

He first appears in Kagetsu Tohya, and later as a playable character in Melty Blood Act Cadenza and Actress Again.
