When Touya returns to the mansion, the problem of taking his brides awaits. Yumina and Linze (mostly Yumina) push and push until Touya accepts his engagements. Even Elze and Yae get to join in the polygyny! Hey, are you okay with this, protagonist?!
You'll regret it for life if 
you don't take us seriously.
لن أسامحك إن لم تتّخذنا على محمل الجدّ
Wenn du nicht Ernst machst,
machen wir dir das Leben zur Hölle.
Nunca te perdonaré
si no luchas en serio.
Nunca te perdonaré
si no luchas en serio.
Vas-y à fond
ou on te le pardonnera pas !
Se proverai ad andarci leggero, 
sappi che te ne pentirai.
Eu jamais o perdoarei se não levar isto a sério.
Ты поплатишься,
если не примешь нас всерьёз.
