Soul Eater is a manga series written and illustrated by Atsushi Ōkubo, and "cosplay" is the practice of dressing up as well-known characters from comics and anime. A Soul Eater cosplayer is any person who uses costume and makeup to portray a character from the Soul Eater series. Cosplaying is highly popular at anime conventions and is done by fans of all ages.
Set at the Death Weapon Meister Academy, the Soul Eater series revolves around three teams, each consisting of a weapon meister and a weapon that can transform into a humanoid. Trying to make the latter a "death scythe" and thus fit for use by the academy's headmaster Shinigami, the personification of death, the students must collect the souls of 99 evil humans and one witch.
Fans of all sorts come together at conventions to engage in cosplay and make themselves look like characters from this story. Fans of the series dress as the students from the school or even as the weapons themselves to show off their loyalty and interest in the manga. Makeup, special outfits, craft supplies and even everyday house items are used to help create the illusion for the cosplayer to show off to fellow fans.
