Midou

A mysterious robe-clad man with a scary smile and giving off an eerie aura. Doesn't even bat an eye upon being attacked by back alley thugs. He only has a major role on Chihaya's route. An assassin under the thumb of Gaian extremist. He controls a familiar named Fuego and has incorporated its latent powers into his own body. He's been involved in warfare from a very young age. His family was slaughtered and he had to live on as an orphan. He discovered his skills as a summoner and joined Gaia. He feels hatred toward all things. After his death, he usually appeared on Kotarou's dreams and when Kotarou lost his consciousness and is always persistently suggesting Kotarou to take also what path he chose - which is to kill anyone who's getting on Kotarou's way especially for the sake of someone particularly Chihaya. At Kotarou's final battle against Sakuya on a huge familiar form, he lend his powers to Kotarou.
