With the information from Kumagami as a hint, the student council members continue a stakeout in the middle of the mountains where a wielder of a special ability supposedly hangs out. As they spend their time barbecuing and fishing, Yu comes across the music of ZHIEND through Tomori's music player. And, the one that appeared in front of them as they continued the stakeout...

The location of the new ability wielder according to Kumagami was the condo where Ayumi was currently home with a cold. Ayumi tells Yu and Tomori who came to see how she was doing about the nightmare that she had. Tomori, thinking that the dream's details can be a hint in figuring out Ayumi's ability, tells Yu to draw out the contents of Ayumi's dream from her...

Yu, crestfallen by the fact that he lost his little sister Ayumi, shuts himself alone inside his home and cuts all communication with the outside world. Denying even the worried student council members that came to check on him, Yu leads a dissolute life only to find appearing before him...

Kumagami and Medoki appear before Yu Otosaka after he successfully rescues Ayumi. Within the laboratory facilities that they take the siblings to, Yu finds out the reason behind the outbreaks of special abilities. Kumagami then gains information regarding a new ability wielder and heads to Hoshinoumi Academy, but...

The friends from student council and Ayumi come visit Yu who is hospitalized from his injuries. Among them is Tomori. During his conversation with Tomori, Yu makes a certatin decision.

The decision that Yu makes is to plunder the ability of every last wielder of a special ability on Earth.

It is a choice that provides salvation to every ability-wielder, but at the same time, it is a choice that makes Yu pay a huge price in return.
