Three years ago, a bloodthirsty race of interdimensional beings known as the Disas appeared and destroyed everything they could reach on Earth. With regular weapons rendered useless, humanity's only hope of survival relied on humans who became magical girls after forming an alliance with the Spirit Realm, who had followed the Disas to Earth. After a violent conflict, the squad of magical girls emerge victorious, with the survivors now known as the Magical Five. Following the war with the Disas, the Magical Five disbands. Kurumi Mugen, Mia Cyrus, Tamara Volkova, and Lau Peipei independently continue their own military services, while their leader, Asuka Ootorii, retires and becomes a high school student. However, Asuka's peace is short-lived, as it seems there were survivors on the enemy's side as well. As magic must be fought with magic, Asuka is dragged back into combat as an even worse battle looms on the horizon.

Fable, an assassin who works in organized crime, has been raised to the legendary status of a ruthless killer capable of murdering any man within six seconds. Six years after his debut, his boss fears that Fable has started to attract too much attention from the legal authorities, and he orders him to hide in Osaka for a year. Accompanied by his driver who assumes the identity of his sister, Fable is bound by a special condition: he must act as a civilian and not murder anyone lest he and his partner lose their lives. However, the seemingly well-deserved holiday soon takes a grim turn. Takeshi Ebihara, the second-in-command of the Osaka mafia that officially protects the assassin, sees Fable's presence as a threat and wants to remove him. Constantly monitored by the yakuza and regularly put in life-or-death situations, Fable has no other choice but to outwit Takeshi's schemes if he wants to stay alive.

Tricked into assassinating his own prospective father-in-law, righteous samurai Raizou Kurima is overwhelmed with guilt. In order to reclaim his honor, Raizou swears vengeance on the lord who gave him those misleading orders. In his pursuit, he is aided by self-proclaimed merchant-of-all-trades Yuuen Usui, who is actually one of the Revengers—assassins who seek justice for the wronged and dispense bloody revenge on their behalf. Tragedy seems destined to follow Raizou as he becomes increasingly intertwined with members of the Revengers. As he begins working as a vigilante alongside them, the complicated web between the corrupt Japanese political elite, the unscrupulous Europeans, and the Revengers gradually reveals itself. The more entangled he becomes in these affairs, the more Raizou realizes that justice is as deceptive as the honor that he sought to redeem.
