Free-To-Play mobile game released on iPhone / iPad and Android devices on the 11th of March, 2014.
This game is not officially a DDP title but it's clear the title exists within the world. You'll find references to bosses, dolls and the like throughout
the game. The characters in Japanese suggest it should be called Don Pachin, I don't know why they've opted for Don Paccin.
In this title, I've seen all three dolls from SDOJ, a few of the bosses from DFK, you can also find
Saya and Hina from SDOJ among others.
