Jube is a short and bulky middle schooler, he has chops as his most striking feature. He dresses himself as a typical Yankii (a Japanese delinquent), he wears his jacket open with torn ends and folded sleeves, black pants, and sandals, he also uses a visored cap, torn at the back that mixes with his hair.
Jube appears intimidating and aggressive at first sight, but he is very kind and friendly towards his friends, being a fan and follower of Pop☆Step, he is willing to assist the vigilantes in capturing distributors of the Trigger drug.
Sword: Jube has a Quirk that allows him to generate wooden swords from his wrists. They are roughly the length of his arms.
- Jube's Quirk and appearance are references to the lone-wolf Marvel mutant Superhero vigilante Wolverine, and possibly to Jotaro Kujo from JoJo's Bizarre Adventure.
