Sawa is a school girl, an orphan, and an assassin. She is being controlled by a corrupt cop who gives her targets to kill, detailing to her the crimes these men have committed in order to justify their death. Some of his power over Sawa has to do with her deceased parents and the promise of revenge. When another orphan, a teenage boy called Oburi, is brought in to assist Sawa, the two teenage killers form a bond of sorts. As they heal each other's emotional wounds, they begin to dream of a life that would not be spent under the shadows of murder.
