A pink beastman who is always with Imura. They've been together a long time, but he still calls Imura "-san" and his way of addressing him is inconsistent. He occasionally gambles on slots or horse racing, and he always loses. He smokes sometimes. A member of the Demon King's Army. He has a habit of slacking off, but he has a hidden kind side. He is Level 3, and his only skill is "Wail." When Imura dies, he rushes to use recovery items. For some reason, he often dies in gruesome ways. He has two horns, but they are fragile enough for a child to break. He is childish and hates dying because it hurts. His equipment is restricted; if he violates the Demon King's regulations, a washbasin falls from nowhere with a rhythmic thud. Currently, the only weapon he is known to be able to equip is a toy plastic sword. First person: I (casual/rough). He isn't popular with the ladies. He's dissatisfied with the Demon King's Army and grumbles about it while slacking off. He is Imura's business partner and they go on missions together. The Demon King is fully aware of his slacking. He appears to have no ears, but likely has small holes. He calls the boss "Demon King-sama."

A green slime. He is skilled at being the straight man. He's been with Kaku a long time but still addresses him as "Kaku-san." He uses the fact that he has no arms to push work onto Kaku, though he considers it an unavoidable reality. He generally speaks politely. He is Level 1, and his only skill is "Self-Destruct," which just makes a loud bang to surprise people without dealing damage. He doesn't care at all about dying. He has a hidden jerk streak; even if Kaku gets taken out, he might just keep the conversation going. He has two (self-proclaimed) horns. He often chuckles with a "Heh," but rarely laughs out loud. His attributes change depending on the potions he drinks—poison makes him toxic-tongued, ice makes him cold and distant. He grows larger in humidity or rain. A member of the Demon King's Army. He gets angry when he needs to; when he does, he drops the polite speech for casual insults like "Stupid," which sound like a grade-schooler's. He can perform a body slam. First person: I (polite/casual). He is more popular than Kaku. He is Kaku's business partner. He tacitly approves of slacking (unconsciously). He lends Kaku gold and pampers him (unconsciously). When drinking, he pulls a straw out of nowhere. He freezes if it's too cold. He cannot shapeshift. When something happens to Kaku or others, he observes nonchalantly. If asked for help in that state, he reacts with a "Ugh, what a pain." He has facial features. His body feels like a liquid with a thin membrane over the surface.
