Monmusu Quest! Paradox RPG [Part One]

Monmusu Quest! Paradox RPG [Part One] is an erotic RPG and the first entry of the Monmusu Quest! Paradox RPG series, which is a sequel trilogy to the original Monmusu Quest! trilogy of adult visual novels. The game takes place in an alternate timeline in which a great disaster forces monsters and humans the world over to work together. The hero, Luka, sets off on a quest to find his father, who has gone missing while on an adventure. He soon runs into a small angel who claims to be the Goddess Ilias and a small lamia who claims to be the Monster Lord Alice. Choosing to take along one of them, the party begins following a mysterious white rabbit on a dimension-hopping adventure to save reality as they know it.

Unlike the original trilogy, which were visual novels with RPG elements, this game is a fully fledged JRPG, taking inspiration from games such as Shin Megami Tensei. Combat is turn-based, with a starting party size of eight, though only four can be active in combat at a time. During a battle, the player can talk to monster girls to recruit them. Almost every enemy is recruitable, and the game features hundreds of potential companions, each with a unique trait. Every character has a job and a race, which the player can change freely.

If the player loses a battle, a cutscene is played in which the monster girl rapes Luka. A consensual version of the scene can also be viewed if the character's affection is raised after recruiting them. The game features many of the same sex scenes from the original trilogy, alongside new ones. Sex scenes that have already been seen can be skipped and all vore scenes can be skipped if preferred. The game can be combined with Part 2 to effectively be played as a single game.
