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.
Mahiru, let's stay together like this, 
even when we grow up to be adults.
،ماهيرو، فلنبقَ سويًّا هكذا
.حتّى عندما نكبر ونصير بالغين
Mahiru. Selbst wenn
wir Erwachsene sind,
Mahiru, sigamos juntos,
incluso al ser adultos.
Mahiru, sigamos juntos,
incluso cuando seamos adultos.
Mahiru,
Mahiru...
Mahiru, mesmo quando ficarmos adultos,
vamos continuar assim, juntos.
Махиру, давай всегда будем вместе, 
даже когда вырастем.
