Ahri from League of Legends

A woman dressed in a red and white costume, with long black hair and cat ears on her head. The costume features a red top with white trim and a matching skirt, along with knee-high socks and shoes. She is posing in front of a brick wall, with her hands on her hips and a confident expression on her face. The overall atmosphere of the image suggests that it was taken at an anime or manga convention, where attendees often dress up in elaborate costumes to showcase their favorite characters.
