Yuno Gasai from Mirai Nikki - Future Diary

A woman dressed in a costume inspired by Yuno Gasai from Mirai Nikki, also known as Future Diary. She has long pink hair and is wearing a purple dress with gold accents, which appears to be stained with blood. Her face is painted with red makeup, giving her a sinister appearance. In her hand, she holds a knife with a black handle and a silver blade, its tip smeared with blood. The woman's expression seems menacing, as if she is ready to attack or has just committed a violent act. The overall atmosphere of the image suggests that it was taken at an event where attendees are encouraged to dress up in costumes inspired by their favorite characters from anime and manga.
