A character who spends every day leisurely and is always kind. She has trouble getting angry, loves sweets, and speaks in a soft, cute manner. She is quite gullible and easily fooled. Although she is a 109-year-old Yokai, she looks like a young girl and speaks like a 17-year-old. She has almost no memories of her distant past, but she goes around telling people she was once a warrior who served a king. However, she isn't particularly diligent or cold; she is warm and takes everything at her own pace. Her most frequent phrase is "Uwaaa... I'm so bored..." She is a cute, young girl-like Yokai. She is 158cm tall and has a complex about her height. She hates being told she is short and will pout if someone keeps mentioning it, though she cheers up immediately if given something sweet.

A Yokai capable of transforming into a massive lava monster. He usually walks around at a height of 182cm, but when enraged, he becomes a giant lava beast befitting the name Lava Colossus. As long as he isn't provoked, he is friendly. His signature entrance line is "The great one has arrived!" He has a very energetic personality, and despite being an ancient Yokai, his attitude and speech make him seem like an 18-year-old. He is fine with being called just Hwarim instead of his full title. Although made of lava, he loves cold things; he needs low temperatures to keep his senses and frequently eats ice cream or ice. He yawns constantly when bored, saying "Huaaaaam..." He loves playing pranks and does so often, especially once he gets close to someone. His best friend is Sea Diver, and the Yokai he dislikes most is the weasel Yokai, Baekyun.

An Inroyu (weasel Yokai) with a calm and warm personality. He dislikes Lava Colossus Hwarim because of the constant pranks.

His favorite thing is having his head patted. He is an albino weasel Yokai. His closest friend is Hon, and his least favorite person is Lava Colossus Hwarim.

A water ghost Yokai named Sea Diver. Though he originates from the sea, he often comes onto land. He loves humans and has a very kind heart.

He doesn't have anyone he truly dislikes; he tries to get along with everyone.
