Just wanted to ask since I do want to buy this game soon 

also just how much is the game Hentai? I want to buy it for the lewdness and stuff, but I cant tell if its primarily a dungeon crawler-ish game or if there is plenty of hentai and if its incorporated into the story.

You can get your first H scene if you managed to survive the tutorial part of the game.

And most of the content, non-story related, or story related, is full of H scenes.

This game is not an easy meet & fuck game, so treat it as an actual RPG game so that you can properly enjoy the H scenes.

There are some lewd clothing in the game but that's a bit later on.

When you start you are going to want to try your best to survive and to fight but if you lose you should not load a save as the fun H stuff will begin the enemies will rape poor Lona and that can be interesting when you have tried but aren't strong enough. If you get raped and captured you can still escape btw.  later when you get good enough you will be able to survive without getting raped and teach those bastard monsters a lesson. 

You guys make great points <3 I appreciate it
