After Subaru plants the flowers that were left behind, she tells Aoi about Minato and the mysterious greenhouse, but she only becomes annoyed that she didn't tell her earlier. Later that day, Subaru seems to find Minato tending the garden, but he denies any existence of a greenhouse. Afterwards, the girls go to capture a fragment that has merged with a comet that is heading towards the Sun. While the others hold off the cloaked boy, Subaru and Aoi, realizing they both share the feeling of being left behind, make up with each other and manage to capture the fragment.
