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.
Phew. That wasn't one 
of the seven mysteries.
.لم تكن تلك أحد الألغاز السبعة
Bin ich froh. Das gehört
wohl nicht zu den Mysterien.
Menos mal que no era una maravilla.
Menos mal que no era una maravilla.
Super,
c’était pas une de ces légendes.
Meno male... Non era uno dei sette misteri.
Ufa. Esse não era um dos sete mistérios.
Пронесло, это не одна из семи легенд.
