Princess Princess D (2006)

In all-boys school with a tradition of Princesses (boys chosen to attend school functions dressed up as girls to alleviate the tension between the students), Mikoto Yutaka, Yuujirou Shihoudani, and Toru Kouno are this year's chosen Princess team. Dissatisfied with the half-hearted efforts of the current Princesses, Otoya Hanazono creates his own team of Dark Princesses to rival for the students' attention.
