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.
Why did we have to go with the 
"we are space aliens" theme, anyway?
لمَ اخترنا موضوع "نحن فضائيون" أصلا؟
Pourquoi on a choisi de partir
sur des extraterrestres, aussi ?
E comunque perché abbiamo scelto
questo tema del "siamo alieni dello spazio"?
Por que inventamos de dizer
"somos alienígenas do espaço"?
Почему мы вообще придерживаемся
темы, что мы пришельцы?
