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.
The night has only begun! 
Leave some fun for later!
!لقد بدأ اللّيل توًّا
!اتركوا بعض المرح لوقتٍ لاحق
Die Nacht hat gerade erst begonnen!
Heben wir uns den Spaß für später auf.
La noche es joven.
Dejemos algo para después.
La noche es joven.
Dejemos algo para después.
La nuit est encore longue,
gardons-en pour plus tard.
La notte è ancora giovane!
Teniamoci un po' di divertimento per dopo!
A noite é longa, precisa
deixar o melhor pra depois.
Вечер только начался! Не всё же сразу!
