Aoi Shiro

Syouko Osanai and Aizawa Yasumi are both members of Seijou Girls Academy's kendo team. While on a trip for kendo training, the two girls one night decide to walk along the beach and stumble upon another girl who appears to have been washed ashore. This girl appears to be mute and can only communicate with facial expressions. The young girl quickly becomes attached to the slightly older girls and starts following them around. Aoi Shiro is a visual novel that has branching story paths that depend on how the player treats the young girl. A PC version of the game was released a few months after the original PS2 version and can be considered an extended port. It added two new story scenarios.
