Season of Books and Keys

A coming-of-age mystery you experience with all five senses

After‑school, small mysteries slip quietly into the library, innocent at first glance, yet steeped in secrets and lies. Join two high‑school library committee members as they unravel each case through sight, sound, and story, turning every clue like a page in a book.
A bittersweet, atmospheric narrative adventure that blends the experience of reading with the feeling of watching a drama.

Season of Books and Keys adapts the novel series by Yonezawa Honobu, the author behind Hyouka, the Shoushimin Series, and The Samurai and the Prisoner, originally published by SHUEISHA Inc. The story is presented with richly colored illustrations and full voice acting, alongside an all-new original episode, 'Used Kitan,' written for this release by Yonezawa. Lead character designs are newly drawn for the game by Yoko Tanji, the illustrator behind the original novel's key visual.
