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.
Without an enemy like that, how can 
I become the hero of an interstellar war?
من دون وجود عدوّ كهذا، كيف يمكنني أن أصبح
 بطلة حرب نجمية؟
Sonst kann ich keine Heldin
im Milchstraßenkrieg werden!
Si no, tampoco protagonizaré
una guerra intergaláctica.
Si no, tampoco protagonizaré
una guerra galáctica.
sans quoi, je serai jamais
l’héroïne d’une guerre galactique.
Senza un nemico così, come posso diventare
l'eroina di una guerra intergalattica?
Sem um inimigo como esse, como posso
me tornar heroína de uma guerra intergaláctica?
Как стать героем вселенской
войны без злодея?
