First thing first, the game itself is really good, but the translation is unsurprisingly bad (for now).
Story: The game is about you using your power from a contract with demon to save your friend. If i remember correctly, there were 4 endings (or 3) in total depends on how your choices during the play through, which is pretty cool and all the endings are pretty good. Another fascinating point is that you can do a virgin run in this game and that's pretty rare in MRPG (i like it).
Gameplay: No grind and easy to play. All you need is going around the town and completing everyone's requests. Most of the quests can be done by being a good girl, or by using your female power. Depending on which ending you want to get, you can easily find the way to complete it. Remember that every action has a consequence and you will get the ending base on how much desire you've gained. So in my opinion, it's really nice and good to see a game that doesn't look like most "copy-paste" MRPG.
CG: The art is good and every scenes are decent. There are many kind of fetish from shota, mind control, harassment to just usual sex. You can also change your MC's looking and the scene will also change with your character, this makes most scenes become really unique and rewatchable. Moreover, the game has a really different way to show the scene so it's good to experience new things.
Map: Well designed. Not too big or not too small. Everything is perfect and has its own purpose. You can easily do all the tasks without running around for minutes like other games so i must say that i like this game's map design.
Overall, this is a pretty good game with all the good points. However, i must give it 4 because of the shitty MTL (Trust me,... the translation is quite bad when comes to sex scenes. For example: iku, oji, ochin, etc). My opinion ? Try if you have a gut or just wait for a proper translation (which will worth it). I'll replay the game and change it back to 5 when there is a better translation, but for now it is what it is.
