After arriving at the beach where the Nilya Ruins lie, Touya and the others take a moment to enjoy the seaside. With so many beautiful girls in swimsuits, Touya's heart is racing!

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?!
