It is here where Hisui gets focus. In the beginning of the route, rather than his sister, Shiki reminisces about two girls from back then, a cheerful girl, who played with him and Akiha, and a girl by the window, who watched them from the mansion's window, never leaving. He recognizes Hisui as the girl by the window and Kohaku as the cheerful girl; this is a mistake, as he later learns while trying to form a relation with Kohaku. Neither of the two remember the times that Shiki brings up in conversation.
