DR 2 Night Janki

DR² Night Janki is a mahjong game with adult scenes. The game has two modes: "Story" and "Regular". The story mode is set in a medieval castle, which is said to be ancient grounds for sorcery, but is currently controlled by the mysterious Rumira, who runs a mahjong club. The hero, a man named Ryuuji, decides to investigate the castle, and therefore has to defeat its inhabitants (all pretty young girls) in mahjong matches.

The regular mode allows the player to play mahjong against any of the characters from the story mode. Three difficulty levels are available.
