* Based on Haruka Ogataya's 4-koma manga series by the same name, serialised in [Futabasha]'s Moeyon magazine from July 2004 to October 2005, then moved to Comic High! magazine until January 2011.
A middle school student finds his ordinary life disrupted when a strange [small magical cat-girl creature] suddenly appears in his refrigerator one day. Sunao Moriyama just takes everything in stride and accepts his new friend as she moves into his life and his circle of school friends. But the funny creature that he named Potemayo (a made-up name from a potato-mayonnaise bread) does not like one of his classmates, specifically Mikan Natsu and considers her a rival for Moriyama's attention. Then a second silly magical demon-girl appears in Moriyama's refrigerator, carrying a scythe and possessing strange magical powers.
