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.
Only one is on now. But why

واحدة منها فقط تضيء. لكن لماذا أضاءت؟
Solo hay una encendida.
Solo hay una encendida.
Une seule s’est allumée.

Ma solo una è accesa. Perché si è accesa?
Apenas uma acendeu.
Mas por que acendeu?
Сейчас горит только одна.
Вопрос в том, почему загорелась?
