Mirai asked Ayumi to try fulfilling Hinoe's last request if she has the strength to do so, and then left the room.
Yoshiki, however, feeling bad to leave her alone, decides to stay, but Ayumi tells him not to worry about her and that she will be fine.
She is in the showers when Yoshiki comes in from the pool.
At one point, Ayumi pushes Yoshiki aside before running off, causing Yoshiki to become concerned and go after her.
After school was over, Naomi talks to Ayumi, feeling worried about her condition and tries to comfort her.
They investigate and find Mayu standing between two girl ghosts.
Eventually they are warned by Sachiko to turn back but they ignore her warning before being knocked out and falling into the waste pit.
Ayumi is no longer a dependent and weak girl who needs to be protected by others, but a strong girl who resolves to save everyone at all costs.
