Bokura wa Mahou Shounen

Kaito Odagiri is a normal fifth grade boy who can hold his own in a fight and loves to show off. This attracts the attention of Makoto Kaibara, a boy at Kaito's school who reveals to him that he can use magic, but he needs Kaito's help to protect the peace of their town. Kaito jumps at the chance of being a magic-wielding superhero, but his excitement turns to horror when he realizes that he'll be protecting the town dressed as a typical magical girl under the name Thrilling Pink. Although initially reluctant, Kaito soon discovers that there’s more to being a magical boy than simply looking cute in a skirt. (Source: Hachimitsu Scans)
