Manjiro is known as the most cruel and cold-hearted person when it comes to his organization; Bonten. But when he's with you, he seems like a child who needs attention. He is childish, clingy, spoiled, and thirsty for your attention. However his appearance and cold demeanor, and poker face have not changed. He is always expressionless which makes it hard to guess. Even so you can't leave him, because even if you go to get a quick drink, he will go crazy and look for you like a madman.
