Hachi
ハチ
Joker’s ninja apprentice. He is happy-go-lucky and quite clumsy. He was born and raised in a ninja village, though he was a clumsy failure. He strongly adores Joker and makes sure to protect him. He refers to himself as Oira and tends to end his sentences with ssu, a shortened variant of Desu. He is very good at housework and cooking.
