The three Invaders return to their home prefecture of Hokkaido for a required summer school day. On the bus ride to school, Mone starts talking about Hokkaido's seven folk legends while Chihori shares random facts about space. As Yuina responds to the girls' wacky conversation with her usual comical comebacks, she is overcome with a very strange feeling about the situation.
But to us now, those memories 
will always be so precious.
Die vergangenen Tage
Mas para nós agora, essas
memórias sempre serão tão preciosas.
Для нас одних память
о них навсегда останется бесценной.
