異界ノ宿帳
Launches 11 November 2026 · PC · Adventure, Indie, Simulation

Story
Supports Japanese and Simplified Chinese text. Includes both Japanese and Chinese voice audio. 『The Guestbook of the Otherworld』 is a hot-spring horror simulation that blends horror, visual novel storytelling, and simulation gameplay. The story takes place in a world that belongs neither to this shore nor the next — the Otherworld. In this realm, forgotten things drift ashore and wander as tsukumogami.
