In Stern Bild City, those with special abilities are called "NEXT," and can use their powers for good or bad. A unique organized group of NEXT appear regularly on Hero TV, where they chase down evildoers to bring limelight to their sponsors and earn Hero Points in the hopes of becoming the next "King of Heroes." Kotetsu T. Kaburagi, known as "Wild Tiger," is a veteran hero whose performance has been dwindling as of late, partially due to his inability to cooperate with other heroes. After a disappointing season in which most of the other heroes far outperformed Tiger, he is paired up with a brand new hero who identifies himself by his real name—Barnaby Brooks Jr. Barnaby, nicknamed "Bunny" by his frivolous new partner, quickly makes it clear that the two could not be more different. Though they mix as well as oil and water, Tiger and Bunny must learn to work together, both for the sake of their careers and to face the looming threats within Stern Bild. [Written by MAL Rewrite]

There is Earth, our familiar world, and then there is the Black World, a parallel dimension that very few people are aware of. For centuries, a pact between the two worlds has been observed to maintain peace, and terms must be negotiated and renewed soon to continue relative harmony. This time around, there is a militant faction that will stop at nothing to prevent the signing of a new treaty for inter-dimensional peace. Two agents of the elite organization known as the Black guards—defenders of the balance between the two worlds—are charged with ensuring the success of the treaty. Director Yoshiaki Kawajiri (Ninja Scroll) blends stylish eroticism, graphic horror and pulse-pounding action as these two race to consummate the peace treaty in time. (Source: AniDB)
