Medaka Box (Manga) [Weekly Shōnen Jump]

      Medaka Box (めだかボックス, Medaka Bokkusu) is an ongoing Japanese manga written by Nisio Isin and illustrated by Akira Akatsuki. Medaka Box is serialized in the Japanese magazine Weekly Shōnen Jump, published by Shueisha since May 2009. The series follows the Student Council of Hakoniwa AcademyHanokiwa Academy , originally comprised of Medaka Kurokami and Zenkichi Hitoyoshi, during their various adventures to honor suggestions presented by fellow students in order to better the academy. These suggestions are received through a suggestion box Medaka institutes at the series start: the titular "Medaka Box" (a play on words with the Japanese term for suggestion box, meyasu box). As the series progresses, more characters join Medaka in her endeavors, and the Student Council face progressively more difficult requests, both serious and dangerous.
