Aoi Shiro is a supernatural action-adventure visual novel of the Yuri/Girls Love Genre. As such, the game has a variety of pairings between different women, with a total of 56 different story pathways to take. Notably, while this is a visual novel in the Girls Love tradition, reviewers have commented  that aside from the “erotic blood feeding” scenes between involving vampires and their respective lovers, there isn’t much explicit sexual content. Nearly all of the endings involve some pairing of women sharing a passionate kiss as well.
