Maria-sama ga Miteru 4th

Synopsis

Yumi and the Yamayuri Council have found two new helpers in Kanako and Toko. Unfortunately, their assistance comes with tension, as neither girl is particularly fond of the other and both seem likely candidates to be Yumi's petite soeur. Will either be a good fit for Yumi? As the school year marches on, the work for the Yamayuri Council piles up, and pressure begins to mount for Yumi to make her final decision. (Source: RightStuf)
