And now he demands that Mao give him the Taizanfukun spell, which has the power to control life spans. But Shiranui isn't the only one who wants it! Then, when the gang floats theories about the origin of Byoki and his powers, Nanoka recruits Shiraha again to help with her research in the present day. Will Shiraha's crush on Nanoka ever be requited, or does she only have cat eyes for Mao? Plus, the story of the attack that left the scar under Mao's eye!"--Back cover.
