Ability users, individuals possessing supernatural powers, first appeared in this world over a hundred years ago.

Today, in a world where ability scores, which measure the strength of one's powers, heavily influence social standing and reputation, our protagonist—Hayato Yanagi—possesses a shocking score of '0'.

Despite this, Hayato inexplicably finds himself drawn into all sorts of predicaments.

This is the story of a boy, technically an ability-less individual by his score, who reluctantly steps onto the grand stage and proceeds to utterly overwhelm those around him.
