A candid and naive cotton-ball like alien Pelu leaves his home world, the all female planet Kotobuki, and travels to Earth to find love and to have a child.

Finnegan was disappointed that the science fiction themes of the story were muted after Pelu came to Earth, until the space hippo made another appearance.

[14] The French cultural magazine Les Inrockuptibles describes the art as both psychedelic and naive, the roundness recalling 70's girls comics and finding the universe to be completely "kawaii".
