You play in the role of a young girl who happens to have lost her memory. But there's a twist. Unknown to her at the time, she is a vampire, a last remaining one in the world at that. After a millennia of slumber, she wakes up to a world foreign to her. You get to help her navigate through a vast modern city and help her come to terms with her vampiric nature, while at the same time trying to recover her memories of the past and form new relationships with the people of the city. The choice on how you approach all of this is up to you.
The game is fairly mild on adult content and most of the focus is on the story. That said, there will still be opportunities to engage in romantic relationships, or more casual one night stand (only on solo path). The game also depicts scenes of extreme violence and revenge plays a significant role so it may not be for everyone! At its core, it is a story full of mystery, secret societies, mysterious figures manipulating from the shadows, betrayal, and so much more.
