Haunted by Monster Girls

A half role playing game (RPG) and a half visual novel (VN). Intro/setting: A few months ago, the demon king has been defeated by the summoned hero from another world. Everyone lived happily ever after...is a lie, for others except humans that is. Somewhere around the corner of the map, there is a castle, a town, and near it is a forest, a haunted one. It’s said that anyone who entered this hated forest will never return, and others said that just going near it will bring you bad luck, and a curse. That’s why they decided to commission the hero to purify this cursed forest...but the fact that this area is around the corner of the map, it would take time for the hero to arrive. Mission: You're an unknown stranger that has been summoned in this setting, and the monsters have taken good care of you, are you going to let them to be slaughtered by the hero? Fight and level up. Disguise that you’re an ally of the human race to use their resources. And when the time has come, fight the hero! P.S. These monsters are girls...
