In a deadly terrorist attack, Arashi Mikami narrowly escapes death but loses everything in the process, including his family and best friend. However, the surgeon that rescues him is far from just an ordinary doctor—he commands a strike team known as Black Label whose task is to exterminate deadly criminals who have fallen too far. Filled with a new determination, Arashi joins the ranks of the vigilante organization. Black Label's targets are aplenty, as evil scum lurks everywhere—dangerous arms dealers, corrupt politicians, and shady gangsters all find themselves hunted by the extermination team. Although haunted by their dark and sinister past, all of the hunters are highly skilled at slaying their targets. In spite of the perilous lives the members live, Arashi and the gorgeous ladies surrounding him still manage to get caught up in a variety of sultry moments and racy hijinks. Though they face strong opposition, nothing can stop Black Label's objective of cleansing the world of ghastly evil.

Years ago, a tragic incident befell a young princess when both her parents died. Devastated, it seemed nothing would calm this poor soul. However, a prince traveling through the area came to see the princess, hoping to cheer her up. After wiping her sorrowful tears, the prince gave her a ring carrying a rose emblem and told her as long as she holds onto the ring, they are destined to meet again. The event leaves a deep impression on the girl, Utena Tenjou, leading her to become a prince herself. Years later, Utena attends Ootori Academy, recognized by the same rose emblem as her precious ring's. There, attracted by the scent of roses, she witnesses Anthy Himemiya tending the flowers, accompanied by the Student Council President Touga Kiryuu and Vice President Kyouichi Saionji, who seem to be arguing over Anthy. While Utena thinks nothing of the occurrence, the Student Council gathers to discuss an important matter. Subsequently, a misunderstanding leads to Utena being dragged into the world of Duelists—those with rings similar to her own. The Duelists fight for the ownership of the Rose Bride, Anthy Himemiya, who is said to possess great power. Wanting to prove her capabilities as a prince, and enraged that Anthy is being wronged and objectified, Utena resolves to fight against the Duelists to save her from the cruel fate.
