Hi everyone,


I have been looking for a dungeon exploration game. As stated in the title, it is a japanese game and the protagonist is male but he goes on dungeon exploring, and he has sex when he is defeated. Along the way he may also encounter allies stuck in the dungeon, but then at some point (forgot the trigger) they will overcome him and have sex with him as well. The other thing I remember is that last time I played it (it was around 5-7 years ago), it had 5 titles. The first one I remember ended quite quickly, finishing in about 2 hours when defeating the final boss.

It is not really animated, more of like in a VN format. Thanks for reading.
