Welcome to the Kowareta Kokoro Wiki[]
The Kowareta Kokoro series (a.k.a. the Yamagata Private Detective Agency series), is a multi-media murder-mystery franchise consisting of visual novels and light novels, created by game developer LockedOff.
Each entry in the series features a different protagonist who is somehow involved with the YPDA (Yamagata Private Detective Agency), a sinister agency that creates as many mysteries as it solves. Though the YPDA is the most consistent element, the mysteries surrounding it are treated as a subplot to the main mystery.
