The Winter International Sports GP in Sapporo is just a month away, and gaining popularity are the three superhumans who had received body modification surgery for the ski jump: the Three Birdmen. However, the three are struck by lightning from a mysterious black cloud and get monstrous beings resembling flowers on their heads. Now it is questionable if they can even participate in the exhibition jump. Another jumper, Amato, is suspected as the culprit as he was feuding with the three for refusing the superhuman surgery. But the black cloud just keeps growing and its lightning strikes more and more innocent civilians...
What if every fabled superhuman existed at the same time, in the same place? Titans from outer space, life forms from a mystical world, phantoms and goblins from ancient times. In another Japan, it’s not just a question of "what if"—it's a reality.
