Alt. Title: 魔法少女☆俺 / Magical Girl Boy
Unpopular idol and junior high school student Saki Uno discovers that her mother, Sayori, used to be a "magical girl", but, as a result of back problems, found it necessary to pass her position down to Saki.
With the help of a Yakuza-like mascot character named Kokoro-chan, Saki is able to transform into "Magical Girl Ore" to fight the cute-faced demons who threaten to kidnap her crush, Mohiro. Unfortunately, her magical girl form is that of a large, healthy, athletic, muscular man in a small, cute, girlish uniform, which is causing endless embarrassment to Saki.
