Wallman

After his country betrays him, Jirou abandons his life as a hitman and returns to Japan, where he feels there is nothing left to care about. His retreat ends when he meets Nami, a working hitman seeking vengeance for her father’s death. Nami is a wallman, a hitman who operates by scaling walls. Through her, Jirou is drawn back into the world he left behind and joins her in pursuing her goal.
