Guchuko

Emerging from Sunao's refrigerator as a mysterious entity, this creature shares a striking resemblance to Potemayo. Named by Kyō Takamimori after her fondness for chocolate guchu balls, she possesses a fierce nature, wielding a skull-adorned axe and discharging powerful energy beams from the worm-like horns on her head. Though she resides in a nearby tree and remains somewhat distant, she has developed a cautious bond with Kyō through frequent snacks provided at school and home.
