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.
And an Impurity Lord awaits 
at each bottom layer.
.وهنالك سيّد نجاسة منتظر في كلّ طبقة سفلية
Un señor de las impurezas
te espera al fondo de cada nivel.
Un señor de las impurezas
te espera al fondo de cada nivel.
Tout en bas
t’attend un dieu des Impuretés.
E al centro di ognuno di essi 
c'è un Signore delle Impurità.
Um Deus da Impureza espera
em cada uma dessas camadas.
А Короли Нечистых находятся 
в конце каждого из уровней.
