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. [Written by MAL Rewrite]

Learning to ride and tame dragons comes easy to most students at Ansarivan Dragonar Academy—except for first-year student Ash Blake, who is known by his fellow classmates as the "number one problem child." Poor Ash is the laughing stock at school because, despite his unfashionably large star-shaped brand that marks him as a future dragon master, he has nothing to show for it. His dragon has never appeared. Until now, that is. One fateful day, Ash's dragon awakes in full glory, but appears different than any dragon ever seen before—in the form of a beautiful girl! What's worse, Ash soon discovers that this new dragon has attitude to spare, as she promptly informs him that she is the master, and he, the servant. Ash's problems with dragon riding have only just begun. (Source: ANN)
