cosplay

A cosplayer in a white and red costume with long blonde hair poses in front of a building with purple-lit windows, then the scene cuts to a different cosplayer with blue hair and a red and white outfit holding a large prop weapon, followed by a cosplayer in a red and black Santa-style suit crouching on a rooftop, then a cosplayer with pink hair and a red and white outfit adjusting a strawberry-patterned mask, and finally a cosplayer in a blood-stained white dress with horns and a black mask standing in a convention hall.
