アシリレラ

Asirrera is a hardworking romanticist who has left the Koropokkur village in order to pursue her dream of becoming a human and falling in love, just like the girl in Koropokkur legend. Although pursuing this dream is her primary goal, she secretly holds yet another reason for leaving the village… She’s clumsy, easily flustered, and a bit ditzy, but she’s genuine and earnest to her very core. Unfortunately, her clumsiness causes a great deal of trouble for our protagonist, Satoru, and she pledges to make amends and help him with his cafe. In addition to the general Koropokkur powers of changing size and how her outfit appears, she possesses the ability to conceal herself from others. [From MangaGamer]
