From Keiichi Sato, the creator of The Big O and Karas, comes Tiger & Bunny - a series that takes place in a fictional, re-imagined version of New York called Sternbild City where "justice" and "heroics" are commercialized commodities. 45 years ago, certain individuals began to manifest superpowers called NEXT and several of them chose to become costumed superheroes. Each is sponsored by major real-life companies which are prominently featured as advertisements on the heroes' uniforms. Their heroic activity is broadcast on the popular television show Hero TV, where they accumulate points for each feat of heroism accomplished and the best ranked hero of the season is crowned "King of Heroes".
The story mainly focuses on veteran hero Kotetsu T. Kaburagi aka Wild Tiger, a middle-aged man with a young daughter, who is one of (if not the) least popular hero in the city's rankings. When his original sponsor is bought out, he finds himself assigned a partner, a young man named Barnaby Brooks Jr, in the first ever hero tag-team. However, Barnaby and Kotetsu have trouble working together as their methods and views clash constantly.
