Crunchyroll is streaming To Be Hero X worldwide, outside of Asia, and describes the main synopsis as:
A world where outstanding heroes are applauded. Here, “trust” creates superheroes. If people believe “he can fly,” he will gain the ability to fly. Conversely, even if a hero has special powers, if he loses trust, he will also lose his powers. Trust is collected as data, and the ranking of heroes changes depending on the value. Once every two years, the top heroes gather to compete in a hero tournament. Their performance there updates their “trust value,” and the ranking is reconstructed. The absolute hero who stands at the top of the rankings, people call him “X”…
