Gray Sky - S1.E7

Yorito and Mana search for Matsuri after she disappears on the night she kissed Yorito. Almost a month passes from Matsuri's disappearance, and Yorito has almost given up hope on her return. On a date out with Aono, Yorito accidentally runs into Matsuri again inside a convenience store and gives chase, leaving Aono alone. Yorito catches up to her to find out she has been living with Mayuko in an abandoned building. Aono is left wandering in the rain alone and is angered by Yorito's desire to be with Matsuri. Back in the abandoned building, Matsuri collapses after being stabbed by a piece of glass by a seemingly mentally vacant/unconscious Yorito who seems to be controlled by Aono.
