Aoishiro’s plot begins with the kendo team of an all-girls school (Seijou Girls Academy) going to a summer training camp which is being held at a temple near the eastern sea, Shoushinji. The protagonist, Shouko Osanai (otherwise known as Osa, her pet name), is the captain of the kendo team and is not a normal high school student. Besides being a highly skilled kendo ace, she’s also very serious, has a dry, sarcastic, almost mean sense of humor, and is described by her classmates as having a personality very similar to a grumpy old man. Along with the club manager, Yasumi Aizawa (Zawacchi, as her best friend calls her), the young but skilled Akita Momoko (Momo, as Yasumi calls her), and the graceful, yet deadly, vice captain, Ayashiro Sakurai. They intend to have a productive experience, however, dark memories begin to surface in Shouko’s mind. Memories of red tsubaki flower petals, a young girl, violence, and crimson blood. To add further complications to their summer, a young, doll-like girl (whom they name Nami) washes up on the beach without any memory or even the ability to speak. Shouko must confront her phantoms, as well as deal with a friendly but dangerous Oni-Hunter, a pale girl with a single red eye dressed in ancient clothing, and many other obstacles in her path to discover the truth.
