Monaka seems to be just an average high-school girl.
In Kite: Liberator (which is more of a spin-off than a direct sequel), ten years has now passed. Could the placid face of an innocent high-school girl really disguise such a ruthless killer? The police call her the Angel of Death, an unfeeling assassin who eliminates targets with grace and precision, leaving only a flurry of feathers across the bloody crime scene as a calling card.But she has a dark and terrible secret linking her past to a murderous police detective and her future to a fatal duel with the one person she loves most in the world.
