Root Letter is an upcoming visual novel adventure developed and published by Kadokawa Games, as the first title in their Kadokawa Game Mystery brand. It is scheduled for a worldwide release sometime in 2016 for both the PlayStation Vita and PlayStation 4. In the game, the player must figure out what happened to the character of Aya, a girl who mysteriously vanished after receiving a particular letter. The gameplay will be split into two distinct parts; the adventure part, where the player interrogates characters who knew Aya in order to find more information about her, and the simulation parts, where the player relives and plays through prior interactions with Aya. Key staff from Konami's LovePlus series of dating sim games will contribute to the game, including character designs from Mino Taro, and producer Akari Uchida.
