Synthesized from 2 Yomimono stories · updated 3d ago

Idea Factory's recent output consists of two Nintendo Switch titles with contrasting premises. On July 9, 2026, the studio released CRAZY CHA!N -Elpis no Kusari-, an otome game set in a world where a war between two European countries has lasted 1000 years. The protagonist, the 17th Jeanne d'Arc, actively rejects her saint role and can choose to save the country or fall in love, which would cost her the saint powers. The game is available in regular and digital versions for 8580 yen and a special edition for 10780 yen, with a campaign offering signed illustration boards as prizes.

In June, Idea Factory revealed a new original dark fantasy IP, Sullyland Nursery Rhyme, also for Nintendo Switch. The game features a talking stuffed animal named Shiro who presents a life-threatening game called Night Lessons, which players must undertake to save townspeople. The game alternates between daytime festival preparation and nighttime survival, and is scheduled to launch on October 1, 2026. Both releases show Idea Factory pursuing distinct narrative and gameplay styles on the Switch platform.
