In order to defeat Impurities that turned out to be far stronger than expected, Itsuki is pressured to perform a "Double Love Ritual" with two maidens at the same time. It is said to produce powerful Star Children, but it has never been performed before. Itsuki steps into uncharted territory, following the lead of onee-san maidens Reone and Falun.
And not too long ago we 
were in a... Love Ritual...
...ومنذ وقتٍ ليس ببعيد كنّا... في طقوس الحب
Außerdem haben wir erst vor
ein paar Tagen das Liebesritual …
Y hace poco hicimos un Ritual de Amor.
Y hace poco hicimos un Ritual de Amor.
Et puis,
la dernière fois, à deux…
E poco tempo fa io e te...
abbiamo fatto quel Rito d''Amore...
E não faz tanto tempo que eu e você
fizemos aquele... Ritual dos Amantes...
И совсем недавно мы с тобой 
совершили... Любовный ритуал...
