Reaper Princess and Library of Monsters Announced for Switch 2 and PS5

A haunting journey through the pages of trauma awaits as Nippon Ichi Software unveils シニガミ姫と異書館ノ怪物 (The Reaper Princess and the Library of Monsters), the latest entry in its acclaimed storybook adventure series. Set to release on April 30, 2026, this dark fairy tale reimagining brings its distinctive hand-drawn aesthetic to Nintendo Switch 2, Nintendo Switch, and PlayStation 5.

Following the emotional narratives of The Liar Princess and the Blind Prince and The Bad King and the Good Hero, this third installment introduces players to Mono, a young girl who ventures into the mysterious 異書館 (Ishokan) facility to rescue her sister from the enigmatic "Shinigami Disease." Partnering with a goat-like creature named Mael, players will navigate surreal, monochromatic worlds representing the psychological landscapes of traumatized patients. Like REANIMAL, this title explores dark themes through unique visual storytelling.

Story and Setting, offering a narrative-focused experience similar to [Persona 5](https://ryuarcade.com/persona-5-the-phantom-x-version-23-launches-with-new-story-chapter-and-character)

The Ishokan serves as a peculiar medical facility housing girls afflicted with Shinigami Disease, a mysterious condition that traps victims within their own distorted storybook realities. Mono must traverse these haunting psychological spaces, each rendered in Nippon Ichi's signature hand-drawn art style that transforms fairy tale imagery into something darker and more introspective.

The narrative explores themes of trauma, sisterhood, and the power of stories to both heal and harm. Players uncover the secrets behind the Shinigami Disease while confronting the emotional weight carried by each patient trapped within the Ishokan's walls.

Gameplay Mechanics

The Reaper Princess introduces two core interaction systems that shape exploration and puzzle-solving. The 紙喰 (Kamikui) mechanic allows players to consume or destroy monochrome elements within the storybook environments, while the めくる (Mekuru) system enables flipping and revealing hidden pages to uncover new paths and secrets.

!Gameplay screenshot and Fate Trigger, games releasing on both platforms should find a receptive audience. Nippon Ichi's storybook adventures join other upcoming titles like Vampire Crawlers in the growing 2026 release lineup.
