Togeharu's Links
Because of his monstrous form, Togeharu doesn't think he can become a hero; acts as a vigilante, though his temper and mild sadism has him acting like a villain at times; Kasui reaches out to him during an internship as a hero in training, and their similarities start to make him think that maybe he really can be a hero too
Aspiring hero, Kasui encounters Togeharu during an internship; they clash, mostly from Togeharu's envy that someone so similar to him could achieve becoming a hero while he couldn't; but Kasui reaches a hand to him, telling him it's not too late to change; the vigilante flees, but it wouldn't be the last time they see each other
