The Sisters which the blood does not lead to, Aoi of the Cabaret-Club Girl and the Airi of the university student. Another person had a secret not to be able to say to two people. Koto that it is the relations that are higher than Sisters. One day the Aoi is in an accident, and the life barely falls into the serious condition in a coma of the thing which I narrowly escaped from death. The Airi which continues watching such an Elderly Sister begins association with the Serina attracted by Airi in younger students of the Aoi. Then, three years later, the Aoi finally wakes up. However, she lost all memory. The Yuria of a beautiful therapist appears for the treatment of defects of memory there…. A finger-tip intertwining with each other, overlapping lips, the body which I demand.
