Maybe Hammer Session? I don't remember there being a janitor though
AHH YESSS THAT ONE thank you :D
i remember at one point the older bald guy was disguised as a janitor at the school
the manga about two dudes (one old, other younger) about to go to the most secure prison but the vehicle they were in crashed and they escaped to a nearby school and disguised themselves as a new teacher and janitor. teaching the most rowdy classroom and leading them to the good path i guess lmao.
