Princess Princess D(2006)

Original title: プリンセス・プリンセスD

An all-boys school with a tradition of Princesses, boys chosen to dress up as girls to create tension between the students. Yutaka Mikoto, Shihoudani Yuujirou and Kouno Tooru are this year's chosen Princess team. Unsatisfied with the efforts of the current Princesses, Hanazono Otoya creates his own team of Dark Princesses to rival for the students' attention.
