Mangan Tawarayama

En and Atsushi's instructor; supposedly killed in an incident by tripping over Wombat and falling down a flight of stairs, Wombat quickly explains that he isn't technically dead. However, he has to remain in close proximity in order to keep the teacher from suffering the effects of decomposition. And uses him as a cover to appear inconspicuous. Tawarayama briefly recovers in "Love, Training Camp and Toothbrushes" but is accidentally injured again, rendering him comatose once more. As none of them witnessed his recovery, they do not know if he is an animate corpse or he will simply wake up soon.
