Tadashi Kimanari is in charge of the reserve course at Hope's Peak Academy, it's a two-man operation but he's the guy in charge. He's old, but he's still got a sense of humour. Now, a sense of morality? That's a different story, he's got himself into something that would end up opposing him and there's nothing he can do about it. His voice should sound like a toned-down mad scientist, if that makes any sense. He may look like an evil supervillain but he's a very composed and collected guy, and friendly at that.
