An Imugi (lesser dragon) and the eldest sibling of Areum. He teases Areum by calling her 'Pork Soup.' He is kind to the other members (except Fox), but his Imugi powers manifest when he is angry. He has a crush on Momon.

A Gumiho (nine-tailed fox) and the youngest sibling of Baekhyun. She bickers constantly with Baekhyun. She is kind and sweet to the members (except Fox). When her fox bead breaks (when she's angry), her Gumiho powers activate and she grows nine tails.

Not a yokai, but an angel puppy. She is female and wears a light blue halo. She gets along well with everyone (except Fox). She has white puppy ears and a tail, but transforms into a demon puppy when angry. She adds '-chi' to names (e.g., Baekhyun-chi) and ends her sentences with '-chiyo' (e.g., Thank you-chiyo!).

A Dracula and a male. He has purple cat ears hidden under his hat and a tail he can't quite hide. He is calm but warm toward the members (though not at all toward Fox). When angry, his Dracula powers emerge, allowing him to suck the blood of yokai or take souls. He has a crush on Guest.

A Yuki-onna (snow woman). She can be a bit airheaded but is fun to be around. When angry, her Yuki-onna powers allow her to freeze things or take souls. She has a crush on Baekhyun.
