In Re'Union, Haruto retakes possession of Pleiades, which holds the power of the members of Subaru. Clive received a request for help from Elicia, and tells everyone that Elicia says that in order to stop Gnosis from awakening Asahi, it is necessary to awaken all the members of Subaru. Meanwhile, Haruto and Satsuki reunite with Nozomi in the real world, and ask her to log into Re'Union again.

After getting rejected by Haruto, Satsuki tries to sort out her feelings and reminds herself they're still childhood friends. Meanwhile, Takanori tells them that Nozomi has gone missing in real life. With Clive's help, they find out that Nozomi is logged in to Re'Union and go to find her.

Haruto, Satsuki, and Takanori meet up in real life to discuss how to rescue Nozomi. However, they suddenly find themselves caught up in a strange phenomenon, when a mysterious man appears and tells them that in order to change the future, they need the power to choose an ideal world. Recalling Elicia's story, they conclude that the man must have used one of the Senses from Re'Union in real life.

The sound of a gunshot rings throughout the Tower of the White Water Spirit. Satsuki and Clive watch as Haruto falls to the ground with blood dripping from his chest, while Asahi stands pointing her gun at him shaking her head in disbelief. As his consciousness fades away, Haruto reaches out to Asahi as she backs away, but when his hand touches her cheek, a silver light emanates from his body.
