Shuranosuke Sakaki, a ronin who wears the mark of two crossed scythes, is hired by the Nakura Clan to rescue Princess Mayu from the Seki Ninja. During his quest, he faces the Seki Ninja's deadliest assassins as he attempts to rescue her. Meanwhile, Marouji, an assassin who kills his targets with his jujutsu skills also carries out his own missions. Sakaki succeeds in rescuing Princess Mayu, but on their return, Lord Daizen orders the execution of Sakaki to hide his involvement with the princess. However, Princess Mayu stops the execution before she suddenly collapses, coughing up blood after being poisoned by the Seki Ninja. Sakaki refuses his reward and leaves the Nakura Clan in disgust. Later, Sakaki crosses paths with the assassin Marouji, both with the strong smell of blood about them.
