Sullyland Nursery Rhyme is an upcoming dark fantasy Nintendo Switch game from Idea Factory, launching October 1. The game centers on a life-threatening night game called Night Lessons run by a stuffed-animal-like creature named Shiro, set in the religious city of Malenis.
Sullyland Nursery Rhyme is a new original dark fantasy IP from Idea Factory, revealed in June 2026 with a promotional video. The game is set in the religious city of Malenis, where protagonists join a life-threatening game run by a talking stuffed animal named Shiro. The core loop alternates between a cheerful daytime festival and a deadly nighttime survival game called Night Lessons.
In July, a character PV introduced the romanceable cast with first-time voice samples, giving the first concrete look at the game's tone. The PV reiterated the dark fantasy setting and the dual daytime/nighttime structure. In August, a CG movie showed actual gameplay footage, covering calm daily scenes and tense moments with the protagonist and target characters. The movie also revealed the ending theme, titled Yūransen (Sightseeing Boat), for the first time.
All three stories confirm the October 1 release date for the Nintendo Switch version. The game blends cheerful surface elements with suspense and dark fantasy, a duality that the CG movie is the first to depict directly in gameplay.
