Shinoa from Owari no Seraph/Seraph of the End

A woman dressed in a costume inspired by Shinoa Hiragi from the anime series Seraph of the End, also known as Owari no Seraph. The costume consists of long, wavy purple hair with bangs and a black dress adorned with gold buttons and a pink bow tie around her neck. She wears a white belt with a large golden buckle and has a serious expression on her face. The background is blurred, but it appears to be an indoor setting with people in the distance. The overall atmosphere suggests that this image was taken at an anime convention or cosplay event, where fans gather to celebrate their shared interests and showcase their creativity through costumes and performances.
