Shueisha Games and developer iMel announced a video game adaptation of Honobu Yonezawa's mystery novel Seasons of Books and Keys for Nintendo Switch and PC via Steam, launching in winter 2026. The fully voiced game stars Kazuki Ura and Yūichirō Umehara, features an original episode by Yonezawa, and supports Japanese, English, Traditional Chinese, and Simplified Chinese subtitles.
Shueisha Games and developer iMel announced the game on Friday, streaming a trailer and opening a Steam page. The title is described as a drama-like adventure, a genre the two companies built for this project to combine reading a story with watching one.
Players take the role of Jiro Horikawa, voiced by Kazuki Ura, one of two high school library committee members who investigate a series of small mysteries. Yūichirō Umehara voices his partner, Shimon Matsukura. Yonezawa wrote an all-new episode for the game, and series illustrator Yōko Tanji designed the characters.
