KADATH, a new studio based in Tokyo founded by game producer Yoichi Miyaji, has announced its establishment and first title, Under Mythos: a dark fantasy RPG coming to Switch and PC via Steam in 2028.
Here is an overview of the game, via KADATH:
■ About
Under Mythos, KADATH’s first project, brings together creators whose credits include some of Japan’s most recognized game titles and series, including Pokemon, Tales of the Abyss, GRANDIA, and LUNAR. The game is a dark fantasy JRPG centered on peaceful days spent welcoming guests at a mysterious hot spring inn and dungeon expeditions in search of food and resources, as the world gradually descends into madness.
Story
A lone cat wanders into another world in search of Mother.
There, the cat discovers a mysterious hot spring inn where the inhabitants of this strange realm come to rest and relax.
Hoping to be reunited with Mother, the cat begins working at the inn, spending peaceful days welcoming and caring for its guests.
But an unpredictable disturbance was already creeping into that everyday life.
Key Features
- A Peaceful Everyday Life That Transforms into Madness – The story begins with peaceful days at a hot spring inn filled with charming characters. As the story unfolds, the familiar world itself gradually transforms into something unpredictable and consumed by madness.
- Dungeon Exploration and Action Combat – To serve the guests who visit the hot spring inn, players venture into dungeons throughout this strange realm in search of food and resources. Players will also face action-based combat against beings transformed into grotesque forms.
- Hot Spring Inn Management x Extraction – After returning safely from dungeons, players use the food and rewards they have gathered to support and develop the hot spring inn. Expanding the inn leads to new encounters and experiences, which in turn open the way to further exploration.
■ Participating Creators
Under Mythos brings together creators who have worked on a wide range of game titles.
Atsuko Nishida, Graphic Designer and Illustrator
Graphic designer and illustrator.
Has worked on the design of various Pokemon. She also works across a wide range of fields, including games, card illustrations, and corporate characters.
“I interpreted Nyarlathotep from the Cthulhu Mythos in my own way, and this little character was born! Nyarlathotep may be
a god of chaos, but I hope this character can become someone people love, just like a familiar cat by their side.”Takumi Miyajima, Scenario Writer
Has written scenarios for numerous game titles, including Tales of the Abyss.
“Who are you? What do you like, and what do you consider happiness? The answers should be different for each of us, yet when we try to convey them to someone else, do they sometimes fail to come across completely and drift away from what we truly desire? I would be happy if we can bring you a sense of ‘comfort’ that exists side by side with those small distortions.”
Noriyuki Iwadare, Composer
Has composed music for numerous game titles, including the GRANDIA series, the LUNAR series, and the Ace Attorney series.
“When I saw the footage, I struggled with how to express the protagonist’s sudden descent into madness. I think the shift from a subtly Japanese-inspired musical style into fast-paced jazz creates a very effective contrast. I’m excited to see how the protagonist develops from here, and I have a feeling the music will continue to change along with that journey.”
Yoichi Miyaji, Producer
Has produced RPG titles including the LUNAR series and the GRANDIA series.
“The peaceful everyday life of a hot spring inn designed to truly comfort the player stands in stark contrast to dungeons where a single mistake could cost you everything. I have spent many years creating RPGs, but this time we are taking on a truly unpredictable hybrid JRPG where the extremes of ‘comfort’ and ‘madness’ melt into one another. With an incredible team bringing this world to life, we hope players will look forward to an experience that may leave their sense of reality shaken.”
