わくわく麻雀パニック！ ～式神伝承～

It is in the shadows between the world of the spirits and the world of the flesh that the Shikigami live -- ethereal fairy-beings given form and flesh in the shape of beautiful elfin girls. Shikigami may be caught by a Shikigami Master, someone who knows the ancient art of defeating them at battle mahjong and binding them with a contract. A man who catches a Shikigami could win everything...but risks his very soul. In the very near future, in the city of Demon Tokyo, a powerful Shikigami Master named Jango lives amidst the bustling insanity of the city. A request for help from a beautiful woman leads to a showdown with the vile Organization. Jingo's world is about to be turned upside down...
