In a world of brilliant heroes, it's the trust of their fans that makes them into superheroes. If the people believe that a man can fly, he will fly. If a hero loses the people's trust, he loses his special abilities. Trust Value is collected and quantified and used to determine a hero's ranking. Every two years, a tournament is held to choose the top heroes. Their performance in the tournament determines their new Trust Values and their rankings. The absolute hero with the highest ranking... His name is X.
