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.
Being watched excites you? 
What a kinky freak!
أمتحمّس لكونك مكشوف؟
!يا لك من مجنون بذيء
Beobachtet zu werden, turnt dich doch an!
Du bist mir eine perverse Socke!
Que los vean los excita, ¿verdad?
Os pone cachondillos que os vean, ¿no?
Ça vous excite
de le faire en public, hein ?
Ti eccita un sacco che gli altri ti guardino, eh?
Brutto esibizionista!
Safadinhos que adoram e se excitam
por ter mais gente olhando!
Нравится, когда на тебя смотрят? 
Ну и извращенец же ты!
