Misa Amane, from the anime and manga Death Note, is an up and coming model who supports Kira. She becomes the second Kira after obtaining the Death Note book, form then on she believes that she can use this to help and bring order to the world by killing those who have sinned. She dedicates her life to Kira (who is revealed to her as Light Yagami) who uses her to find the real identity of L.
The artwork above was done by IreneAstral who personally I think she has done a fantastic job of creating and bringing alive to this character. On top of that I really like her expression and her body language. Nevertheless, be sure to check her other cosplay out, as well as to share the page and comment below telling us all how awesome it is.
