About a year after Kotetsu Kaburagi's identity as Wild Tiger went public, Apollon Media's new owner fires him and reassigns his partner Barnaby Brooks Jr. to the First League, giving Barnaby the flashy new hero Golden Ryan as a replacement partner. As Sternbild prepares for its Justice Day festival honoring the city's legendary goddess, a mystery tied to the celebration forces Kotetsu and Barnaby back into each other's orbit. This entirely new story, not a compilation, follows directly from the TV series' ending.
