The studio was founded in January 2026 by producer Yoichi Miyaji, whose credits include the LUNAR and GRANDIA series, and Under Mythos is its first project. The protagonist is a single cat that wanders into another world while searching for its Mother, arrives at a mysterious hot spring inn where otherworld residents soak, and works there entertaining guests while wishing to reunite with Mother. The game system combines hot spring inn management simulation with extraction: players explore dungeons for ingredients and resources, fight action battles against grotesque transformed beings, and return safely to put the ingredients and rewards back into running the inn. Developing the inn produces new encounters and experiences that lead back to exploration. The familiar world gradually mutates into an unpredictable madness as the story progresses.","whyItMatters":"Kadath's stated goal is to restore Japan-originated JRPGs and original IP, and its producer frames the project as an indie-minded effort to court fans from the planning stage.","webCardHtml":"\u003cp\u003eCharacter design is by Atsuko Nishida, who designed Pokemon including Pikachu and Charmander.
