Bakumatsu Famiglia

Aoi Yuu is a high school student who transfers to a new school due to her parents' remarriage. The school is an elite all-boys boarding institution for students who carry memories of the Edo bakufu loyalists. She shares a room with a student who possesses the memories of Hijikata Toshizou from the Shinsengumi. This encounter triggers Aoi to remember hidden memories within herself. She then begins a hidden school life filled with these emerging recollections.
