NPC Kan!? Isekai Shoujo to Muteikou Ecchi! (RJ01290097)

This work is an RPG where you, the protagonist, have sex with passive and unresisting girls in another world.
While exploring dungeons, you find girls, add them to your party to strengthen your forces, and set off to new dungeons in search of more girls!

There are five dungeons and five girls. Once you gather all of them, the epilogue will be unlocked.

The game includes RPG elements such as battles and exploration.
The overall difficulty is relatively easy, but you can use cheat mode to progress even more smoothly, and you can also unlock all erotic events from the beginning.
