Synopsis
Sunao Moriyama discovers a peculiar, cute creature that he dubs Potemayo. The little being soon starts trailing him everywhere, often riding atop his head. This find quickly becomes the talk of his classmates at school. Not long after, another similar creature shows up and is named Guchuko by one of Sunao's classmates. But Guchuko seems to have a much less amiable disposition than Potemayo.
