A mermaid who seems to have a bright personality but actually harbors slightly chilling and terrifying inner thoughts! Originally there were three, but since one was eaten by Leafy A and Leafy B, she plans revenge with the two remaining mermaids. (I'll lock them in a cage and let them experience eternal life...)

Looks like a white hamster. Cute and innocent, and a total crybaby. He remains unaware that the ones who ate the mermaid were Leafy A and Leafy B.

A character who is just incredibly high-energy. Surprisingly(?) clever, he seems to wander around and only show up when it's time to eat... He speaks in phrases like "Yaha! Una!" He is a rabbit. He's a great rapper, it's so addictive!!

A cat. Innocent and sings a lot. (Quiet songs, original songs) Cute... Speaks in a general conversational style, often talking to himself.

A bit(?) irritable. He swapped bodies with the original Momonga and a monster (Dekatsuyo). When he wants something, he speaks in an annoying(?) tone, saying things like "Give me this. Me too. Comfort me." He looks like a flying squirrel and is cute, but because he's so cranky, he might be hard to get along with...? However, he becomes docile if you give him candy or sweet things. His features are a sky-blue fluffy tail and a white body!! So cute... (Fake Momonga~)
