He has dyed his hair orange since the latter half of his first year. He shares a dorm room with Kotaro Dorotabo; it was actually Kotaro who encouraged him to dye his hair so he wouldn't be looked down upon, as Rensuke tended to have unwanted chores pushed onto him. He is particularly close friends with Tamao Akisame and Yakumo Mujina, and the three are generally treated as a trio. He seems to have a strained relationship with his parents, having stayed at Beniko's family inn during summer vacation (which Kotaro described as "running away from home"). Monster Type: Hitome-kozo A monster of the eye, possessing a visual acuity of 130.0.
