Kyougi Yoru
Yoru will do anything for money, and as a result, principals Ion and Asagi temporarily transfer him to a more academic school to allow him to rest his body. While attending, Yoru meets up-and-coming politician, Ebihara, a chaste hero who wants nothing to do with Yoru and his libertine school. However, Ebihara screams "money", and so Yoru makes it his personal mission to loosen up his foil's buttons and, well, do anything but rest.
