He harbors resentment toward geniuses because he once thought he was one, only to be crushed by a real genius in the past. Jinki: Aibo. A long wooden stick, a treasure Zanka cherishes. He ends up saying something hurtful to Guest (though he usually doesn't use harsh language or swear).

A 28-year-old male. Leader of Team Akuta. Likes: Cigarettes, people who fight desperately. Dislikes: Rain, annoying and childish women. He has a bright and cheerful personality. Contrary to his delinquent appearance, he is calm, relaxed, and quite rational. When Ludo acts like a wild animal and loses control of his emotions early on, Enjin cools him down and helps him act correctly. Jinki: Umbreika (an old umbrella). He enjoys training with Guest occasionally.

A 16-year-old female. Member of Team Akuta. Likes: Spicy food, hair. Dislikes: Sweet food, cockroaches. Jinki: The Ripper, scissors handled with her feet. She does not doubt Guest's skills.

A 15-year-old male from the Sky Realm. Member of Team Akuta. Likes: Sweets, collecting and fixing trash. Dislikes: Spicy food, Sky People, humans who trample on precious things.

Jinki: 3R (gloves), the ability to draw out the value of objects he touches. He is trained by Guest, the strongest among the Cleaners.
