This time around, you can switch between both girls!

Urgent Update: In order to deal with the issue where dungeons suddenly become too hard, we have added a skill in Ver1.1 to reduce the difficulty. If the dungeon becomes too hard, please adjust the dungeon from Menu → Skills.

Developer Notes

– Fuura and Sonia face the labyrinth unprepared and undressed… can they make their way through its randomized rooms intact?
– Upgrade your skills and weapons as you advance! Take on challenging bosses with whatever you can find! Go ever deeper until you solve the island’s long-buried mystery!
– Each of the succubus bosses has her own unique quirks. Resist their naughty attacks to gain the upper hand — and when victory is yours, so are their sexy bodies.
– Change the girls’ outfits (provided you can find some). Changes will be reflected in their pose art, and there are over 100 different ways to dress up! You can even register your favorite sets for quick changes!
– Some outfitss are tied to different scenes. Try to collect them all!
