Tatsumi heads for the capital despite warnings about the area's dark nature as he needs to raise money for his village. Shortly after arriving, Tatsumi is robbed by a woman and has to sleep in the streets. However, he is invited to the manor of a young rich girl named Aria, who takes pity on him. As he waits for his best friends, Sayo and Ieyasu, to arrive in the capital, Tatsumi learns of an assassin group named Night Raid, whose members are wanted for numerous murders. One night, the group appears and starts killing Aria's guards and her parents. Tatsumi faces off against Night Raid member Akame, but their duel is interrupted by Leone, the same woman who robbed him; she reveals to Tatsumi that Aria and her parents has tortured several people from the countryside, including Ieyasu and Sayo, the latter already being dead. Tatsumi kills Aria just before Ieyasu dies and Leone, impressed with Tatsumi's ability to kill mercilessly, invites him to join Night Raid.
