The next day, Subaru is surprised to find Aoi and the rest of the girls are all a part of her class, with her classmates seemingly having their memories rewritten. The Pleiadian believes this to be because of everyone's fates converging caused by his spaceship, which also seems to be related to Subaru and Aoi's contradictory pasts. With the story behind it put on hold, the girls teach Subaru how to ride her drive shaft, after which Subaru appears to be conflicted over her relationship with Aoi. She once again arrives at the mysterious greenhouse where the boy, Minato, assures her that Aoi is probably having the same worries as her. Taking his advice, Subaru and Aoi take to the skies to talk things over and become friends again.

However, some interference by the cloaked boy causes the fragment to launch up into the stratosphere. Managing to utilize Subaru's power, fellow member Itsuki helps bring everyone up to the stratosphere to obtain the fragment before the boy can.
