Özet: Sawa is a school girl, an orphan, and a hitman. Shes under the control of Akai and Kanie, who give her targets to kill, detailing to her the crimes these men have committed. Some of Akai and Kanies power over Sawa has to do with her deceased parents and a pair of earrings that are her prized possessions. Akai and Kanie bring Sawa in to assist another orphan, Oburi, with a multiple hit. Oburi and Sawa become friends, and this friendship may give Sawa the strength to break from her controllers, whose crimes against her are as abusive as the crimes ascribed to the men they have her kill.
