Hi i remember playing a demo of a game where you play as a female ninja, it features quite good H-battle.
I remember the tutorial stage starts with powerful mc but the tutorial boss trap the mc and drained her power, after the tutorial ends the mc saved by her friend and brought to a village with a mission to enter a japanese mansion/castle?? the demo ends after a mini boss/mid boss in the castle.
