Developer Unknown X is throwing the dice on a bold new spin-off. Marisa of Liartop Mountain, a digital tabletop adventure RPG inspired by old-school gamebooks, is headed to PC via Steam on September 18, 2025.
Set in the Touhou Project universe, this standalone adventure puts players in the role of shrine maiden Reimu, who dives into a mysterious book to track down the missing Marisa Kirisame. With fate balanced between player choices and dice rolls, every journey promises to be different—and a little chaotic.
It’s a Gamebook. It’s an RPG. It’s Pure Touhou Tabletop Vibes.
Drawing direct inspiration from physical choose-your-own-adventure gamebooks, Marisa of Liartop Mountain offers a unique blend of narrative exploration, dice-driven combat, and branching paths where no two playthroughs are the same.
You’ll explore a magical world, make decisions that shape your story, and battle through encounters where your fate hinges on a roll of the dice. All the while, Remilia, Flandre, Patchouli, and Sakuya from the Scarlet Devil Mansion provide chaotic commentary, support, and sass—whether you want it or not.
