Guchuko is another mysterious creature that appeared in Sunao's refrigerator, and is somewhat similar to Potemayo in appearance. Guchuko is named by Ky� Takamimori shortly after she ran into Guchuko at school. The name Guchuko is derived from a small chocolate ball called a guchu which Guchuko likes to eat, and -ko (�, -ko?) added at the end, since it is a common ending for female given names in Japan. Guchuko carries an axe with a skull on it, and can fire strong energy beams from two living horns (or possibly worms) on either side of her head. She has a very self-sufficient personality, and has only partially warmed up to Ky�, who often gives Guchuko food when at school or at home; Guchuko sleeps in a tree right outside Ky�'s house.
