The birth of a glowing child marked the beginning of unusual events. He possessed abilities called quirks. The holders of such specific gifts began to be born more and more frequently, which naturally affected the structure of society. A new and in-demand profession emerged, namely that of a hero. To engage in such activities, a license was required, and most often, groups of such specialists were formed, and heroes were attracted to perform difficult tasks. However, there are those who act at their own discretion, and they created the alliance "Justice Achievers".
Koiti Haimavari, on the other hand, pondered more about his problematic quirk, which involved the ability to move quickly, but on all fours. And people were accustomed to admiring only what they looked up to. He himself was enthralled by Kozuho Haneyama, a girl endowed with the quirk of leaping. She effortlessly soars to impressive heights. Moreover, this beauty professionally sings songs. The guy only watches her from the sidelines, unaware that his life will soon undergo a radical change, and he will transform from mediocrity into someone remarkable.
