Marisa of Liartop Mountain is an adventure RPG inspired by tabletop gamebooks, where dice rolls and fork-in-the-road choices determine the outcome of a branching story with multiple endings. As Reimu, step into a literary wonderland while in search of Marisa’s whereabouts. Four Touhou heroines will guide, help, and support Reimu on her journey, but which one should Reimu listen to? ■ Story Marisa, Reimu’s close friend, has suddenly disappeared— In her search, Reimu of Hakurei Shrine stumbles upon a mysterious book. Inside, she finds herself in a world filled with strange inhabitants, and a hollow, empty Marisa standing before her. 'What do I want to be, Reimu?' Can Reimu navigate the mountain of lies clouding Marisa’s heart and bring her back? ■ About This Game ・Tabletop-style RPG You play as Reimu, exploring the dungeon within the book <Liartop Mountain> in a quest to save Marisa. There is one main story. Yet the path branches out in many ways according to your choices and the roll of the dice, which then converges to the ending of your journey. Though digital in form, this RPG recreates the feel of a tabletop session, focusing on replayability and the thrill of shaping your own adventure. ・Dice Inventory Sometimes, luck is part of your choice. Dice rolls influence story events and combat outcomes, but it’s not just about a single six-sided die. As you progress, you’ll acquire special dice with unique properties; High-value dice, intentionally low ones, or dice with identical faces. Combine them wisely, and master your fate. ・Choices and Growth with Scarlet Devil Mansion Characters Remilia, Flandre, Sakuya, and Patchouli often chime in, offering their own opinions as selectable choices. Sometimes their advice helps, sometimes it’s meaningless, or even troublesome. But by embracing their suggestions, you may gain access to powerful dice. ・Rerolls By spending CP, you can reroll and overturn unlucky outcomes. CP can be increased by leveling up, though doing so makes it harder to raise other stats. Will you build skill through growth, or rely on luck through rerolls? The choice is yours. ・Music by RD-Sounds The soundtrack is composed by RD-Sounds, known for unique and evocative Touhou arrangements. Enjoy their distinct take on Kirisame Marisa and the world of Touhou, crafted exclusively for this title. With the DLC, you can play the game accompanied by RD-Sounds’ handpicked Touhou arrangements, an experience like no other. ■ Participating creators Scenario Outline: Hugo Hall Music: RD-Sounds Theme song sung by Sarasa Toumi Game Master: NEKI Director: Masatoshi Tokuoka Kirisame Marisa Voiced by Mariko Honda This game is based on Touhou Project.
