Tatsumi is a fighter who sets off to the Capital in search of a way to make money to assist his poverty-stricken village. After falling victim to a robbery by a woman and losing all his money, Tatsumi is taken in by a noble aristocratic girl by the name of Aria. In the following night, Aria's place is attacked by a group of assassins known as Night Raid. While Tatsumi at first tries to defend Aria from the assassin Akame, another member of the group stops the fight. She reveals that Aria has kidnapped several villagers and tortures them for fun. Shocked upon seeing the tortured villagers — including his two best friends, Tatsumi kills Aria.
