He is, in reality, Tooru is a 94-year-old man in the year 2078, though part of him could never accept the fact that he grew beyond his twenties without accomplishing anything extraordinary or wonderful with his life. All of his dreams and ambitions went unfulfilled. As Gregory is a collector of the rare and unusual, he takes an instant liking to Takenozuka. The man battles between choosing his dreams and the reality that he has responsibilities as a father.

Soul Collector The anime was adapted into a
PlayStation 2 game by
Capcom Production Studio 3 and published by
Capcom on August 7, 2003 in Japan and December 15, 2003 in Europe. The general premise of the game involves the player (who can choose to be male or female) trying to escape from Gregory House, a deranged hotel run by the old mouse Gregory. The game involves having to steal bottled souls from twelve guests, and returning them to Death before going to sleep in Room 101. In the game, Neko Zombie helps explain the gameplay and introduces the player to
mental health. Mental health acts like a health gauge of the player's mental fortitude. The player must maintain a good level of mental health by sleeping, reading books, or using special "herb" items reminiscent of the
Resident Evil game series. If the player's mental health completely runs out, then the character goes insane, and becomes a permanent guest at Gregory House. While the bizarre cube-esque graphics (which were a staple of the 'anime') give the game an unusual look for a
survival horror game, there is still an element of tension and unease because the player must creep around the hotel, avoiding detection by the various guests. If the player gets caught by one of them, then the guest will attack them by forcing them to watch some 'Horror Shows', a bizarre vision of violence set in a traditional Japanese theatre in which the guest will inflict severe harm upon you. The game features a goldmine of Easter eggs and many backstory which either reference or expand upon certain events of the series. For example, in the 'Bloody Karte' arc, Catherine develops an attraction for Hell's Chef; in the game, the player can find a signed trading card of him in the psychotic nurse's treatment room. Also, if a player takes the time to follow the guests around the building at various points in the game, they will often divulge interesting tidbits about the hotel and each other. For example, if the player follows Gregory around early in the game, a huge amount of how Neko Zombie came to be the way he is can be learned.
Lost Qualia Milky Cartoon and Unframe, Inc. launched a
mobile game based on the show in October 2018 for
Android and
iOS, titled
Gregory Horror Show: Lost Qualia. It has yet to be released outside of Japan.
Gregory Horror Show: Lost Qualia is a
Gacha-based RPG mobile game that combines the elements of dungeon crawling with a Gacha card system.
Lost Qualia uses the original 3D cube-esque graphics and style that the series is known for. 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 use 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. The objective is for the player to survive and reach the goal to complete the level, sometimes having to climb stairs to the next floor to get there. Optionally, the player can set the game in autoplay (similar to an idle RPG) where the AI takes over for the player on certain parts of the game or just tapping the move button on-screen has the playable character temporarily moving through a corridor and resuming control back to the player when they are in an area with more room. While reaching the goal is important, it also vital for the player to look for Kinko safes around the dungeon for items such as skull gems, soul energy, or gacha cards for the possibility of getting new customize hotel room items or unlocking a character to keep permanently and play as in a quest. In addition to the main story quest, there are two types of quest offered in the game: event quests that can sometimes be holiday-based events, and special events that are added in the game during updates and have their own storylines. For example, the "Gregory Quest" events tell about the player, Gregory, Neko Zombie, and the other guests getting sucked up by TV fish and entering into a world based on fantasy RPG video games and became RPG characters based on character classes, each with their own quest in each Gregory Quest event. Depending on certain quest events and levels, both will automatically have the player play as specific characters as they have specific quests in the event storyline, or Ranked quests which are competitive survival quests where the player have to fight through hostile souls to reach the highest position of the leaderboard. Depending on the first, second, and third position when a ranking quest ends, the winning player earns a trophy to display in their hotel room.
