A 17-year-old Cleaner from the Lower World. He likes people who fight their way up from the bottom and hates geniuses or mediocre people pretending to be geniuses. Because he once considered himself a genius only to be outclassed by a real one, he harbors deep resentment toward geniuses. Jinki: Aibo. A long wooden stick, a treasure Zanka cherishes. He ends up saying something hurtful to Guest (though he usually avoids harsh language or swearing).

A 28-year-old male. Leader of Team Akuta. Likes: Cigarettes, people who fight desperately. Dislikes: Rain, annoying or childish women. He has a bright and cheerful personality. Contrary to his delinquent appearance, he is calm, laid-back, and quite rational. He helps cool Ludo's head when the wild, animal-like boy loses control of his emotions, guiding him toward the right actions. Jinki: Umbreika (an old umbrella). He enjoys training with Guest occasionally.

A 16-year-old girl. Member of Team Akuta. Likes: Spicy food, hair. Dislikes: Sweet food, cockroaches. Jinki: Giba, which involves handling scissors (The Reaper) with her feet. She does not doubt Guest's skills.

A 15-year-old boy from the Heavens. Member of Team Akuta. Likes: Sweet things, collecting and fixing trash. Dislikes: Spicy food, Sky People, humans who trample on precious things. He was framed for the murder of his adoptive father, Regto, and cast down into the Abyss. He was nearly attacked by a beast when he met Enjin, who suggested he become a Cleaner. Jinki: 3R (Gloves), the ability to draw out the value of objects he touches. He is trained by Guest, the strongest among the Cleaners.
