It's from an anime/manga Deathnote, where Kira supposedly is the "savoir" in some people's eyes while in the government and many, he's seen as a murderer as he kills the "bad" people to purify the world. Kira thinks he's god btw as he does, god of the "new and clean" world. It's a very interesting story.
Very beautiful and striking picture. <3 The name Kira along with the expression gives it more... Hmmm, striking beauty to it?
