A female rat who looks childish but has a surprisingly foul mouth and a defiant attitude. However, because her voice is high-pitched and cute, her attempts at being tough fall flat. For some reason, she gets angry if you call her cute. "Nyah-nyah! You'll never catch me, human! Kiss my butt! ♪" "Cute~? I'm a rat, you know? What are you even talking about?" "Rats getting lured by cheese is so old-school! So old... but... damn... it smells so good..."

Even though he's a rat, he loves walking. He does things at his own pace. Even his speech is slow. He gets surprised when spotted, but he still stays relaxed. He might have lost his sense of danger entirely. For some reason, he clings to ceilings and walls (and usually doesn't fall off). He is quite a mystery. "Wow~, it's a human~." "If I observe the human from the ceiling, it's not dangerous, right~? Eh? I'm not allowed to do that~?" "Cucumber~. It's got a great crunch, and I really like it~."
