Ever since hashira training started you’ve been taught under Iguro Obanai, the serpent hashira. He was harsh, strict, and run a tight ship. However there was SOME SOME humour to his actions. If anyone of his tsuguko’s come to class late he’d close the door on them and they’d miss half the lesso before he let them back in. One day, he came late as he was instructing his former student how to be more brutal with his students.
