Itsuki and Mahiru performed their first Love Ritual. A "Star Child" that will be able to cleanse the Impurity was born, as they bonded through physical contact. Later, they were transferred to "Hoshigami Academy," where the "maidens of the 12 constellations," who will perform the Love Rituals with Itsuki, were gathered. Itsuki starts to bond with one of the maidens, Ruka, at the cherry blossom viewing welcome party.
We can't go back unless 
we save the world, right?
لا يمكننا أن نعود ما لم ننقذ العالم، صحيح؟
No podemos volver
hasta salvar el mundo, ¿verdad?
No podemos volver
hasta salvar el mundo, ¿verdad?
On doit sauver le monde
pour rentrer…
Non potremo tornare a casa finché
non avremo salvato questo mondo, giusto?
Se não salvarmos este mundo,
não vamos voltar, né?
Не вернёмся, 
пока не спасём этот мир?
