Ochiai Osamu

The school janitor.
He has a burn mark across his face that he always tries to cover with his hat. He’s been working at the school for a few years now, but since he has a gloomy atmosphere that doesn’t stand out, there aren’t many students who know about him. He mostly just does odd jobs around the school, which sometimes help out in a pinch.

His real name is Tachibana Takashi (橘貴志).
