Jiro Watabe, the Ultimate Correctional Officer, grew up around a lot of law enforcement figures. Being a Correctional Officer he is very orderly and is a stickler for the rules. Jiro doesn’t know his own strength sometimes, he’s clumsy and accidentally causes damage to objects when he didn’t mean to.

Jiro tries to cooperate with everyone to try and keep a killing from taking place. He’s also cocky; he thinks he can handle every situation by just saying “I got this” then somehow fixing the problem. Jiro tries to get everyone to follow by his rules and regulations but many people (especially Koi) ignore him and brush him off like he has no authority there.

Jiro’s voice is close to Nekomaru’s, having more of a deep voice than everyone else.
