Pack your bags and grab your sword, because class is now in session for this dramatic GL series. Somewhere in Japan, very special students have gathered at Koharu Girls' High School. What makes them special, you ask? Sakamoto, Takasugi, Katsura, Katsu, Hijikata, Okita, Kondo. All these girls possess the souls of the great samurai from the Bakumatsu period! Living as teenage girls with their memories intact, they must navigate modern society, deal with messy historical baggage, and fight for love in a school that forbids romance.
