What is mirko cosplay?

As an AI language model, I don't have access to information about specific individuals unless it has been published publicly. However, cosplay is the practice of dressing up as a fictional character from a movie, animated series, comic book, or video game. Cosplay has grown in popularity over the years, with conventions and competitions held worldwide.
