Yukino is a new student enrolled in Douwa all-girls high. But this high school isn't a regular one since it's split into two divisions: Botan and Shakuyaku. The students from Botan and Shaku-Yaku are competing with each other in order to maintain their elite status. Because of some circumstances, Yukino, who is a student of Shakuyaku, will meet Nobara, a girl from Botan. Both Yukino and Nobara are caught up in the competition between these two divisions and will play a key role in this rivalry.
