description About

In the past, Yuko is back at school while Yu is still missing. Both of them realize their love for each other, and are helplessly in love. At home, Yuko's brother goes on a rampage and throws Yuko onto the wall, where Yu intervenes and is beaten by Yuko's brother. Yuko's brother takes a look at Yu's sketchbook and takes it with him into his room, where he goes insane and starts drawing his deceased sister. He burns the drawings along with himself. In the present, Mizuki receives charms from Chihiro and Kei, which are keys to the roofs of the two Otowa Academies. Kuze realizes that he wants to live and that now he is all alone.
