Derived from an Alice Soft game. Kyouya serves as an instructor at the Andrude Ocean School, a vast floating metropolis. Three years prior, he rescued Kisaragi Miyu, an event that fostered her concealed affection for him. Her twin, Yumi-an android created by their deceased parents-assists Miyu in pursuing this love. However, Yumi's own loyalties are divided between Kyouya and her sister, as she carries Miyu's implanted memories. A separate narrative centers on Kyouya and Yui, who is the younger sibling of Masumi, Kyouya's first love.
