The main storyline tells of the player showing up at Gregory House, where Gregory the manager himself meets the player and tells him about a previous guest known only as "that man". Gregory further explains that the guests delusional beliefs has gotten far too powerful, and that he is able to take over the hotel, turn it into a dungeon, and distort the surreal world around it. Gregory wants the player to help him and the other guests on a quest to take back Gregory House and defeat the man, who is mad with delusional power. The main quest also takes the player and company outside the hotel to the cactus sibling's homeland, (seen in volume 3) which is called Cactus Land. The quest also takes the player & co. to Roulette boy's casino. Like the PS2 video game, The player has a hotel room that serves as the central hub when they finish the tutorial or start up the game. They are able to customize their room with items they get either in a quest or in the Gacha cards from the fortune teller, level up their characters, and manage their Gacha cards and deck to us in a quest. Occasionally and randomly, Gregory, Neko Zombie, Catherine, Hell's Chef, and other playable characters will drop by to visit the player in their room talking to them and offer their support in a quest where the player is able to optionally choose them and play as them in any level. If the player has a playable character unlocked from either in a quest or found in Gacha card pack they can engage in conversation with the other visiting characters in the player's room, usually giving their commentary on the player, the current situation, and chat among themselves based on relationships they have with the other characters, or different topics. The game has the player, Gregory, or other playable characters going through a labyrinth, where they battle through hostile mages and souls that lurk in the dungeons and can appear from anywhere. Using melee attacks, throwable or ranged items, or using Gacha cards to regain health, buff their attacks or speed, special abilities, and using "horror show" Gacha cards to even the odds with one or many hostile souls surrounding them.
