Full Ani

Yuu Morozumi is a student who has high academic potential but spends most of his time playing online games in his room. When his childhood friend and neighbor Rinko Sakaki comes to visit him one day, lightning strikes Yuu's room, knocking them both unconscious. Upon waking up, Yuu finds that he has been transported into the world of the game he was playing, with himself in the role of the hero and an amnesiac Rinko as the starring princess. Yuu resolves to beat the game so that he can return to the real world.

Full Ani is an 18+ mahjong game which, like the name suggests, features fully-animated scenes throughout the entire game, being akin to an interactive anime where the interaction comes in the form of games of mahjong played against computer-controlled opponents. Players take on the role of Yuu during these matches, with the outcome of each match influencing the direction of the story. Depending on the player's skills and victories, Yuu may end up having sex with several of the female opponents. The game features full Japanese voice acting for all characters.
