To Be Hero X is a Chinese-Japanese original donghua and the third installment in the To Be Hero anthology series. Set in a world where belief fuels superpowers, the series explores a unique premise: if enough people believe someone can fly, that person actually gains the ability to soar. But there's a catch—lose the public's faith, and the powers vanish.
In this society, heroes are constantly being monitored, their trust levels quantified and ranked. Every two years, the top-ranked heroes face off in a high-stakes tournament where their popularity—and power—are put to the test. At the pinnacle of this system stands the ultimate hero, known only as “X.”
