Jin Ootomo

Harutora's homeroom teacher. A fairly quirky fellow who tends be more laid back then one would expect from a teacher, to the point where some would accuse him of being irresponsible. Despite that, he's usually good at giving solid advice to students and is known activist against the school's harsh policies when comes to education. He lost his leg in a clash with Ashiya Douman and now has a prosthetic leg.
