Win Bird is a poor boy who, despite losing his parents, yearns to become a knight and trains himself relentlessly.

However, due to his hopelessly low magical power, he couldn't pass the knight examination. Branded with the disgraceful label of "Perennial Knight Cadet," he spent his days being mocked even by the juniors who surpassed him.

Then one day, the Hero defeated the Demon King and saved the world. The Hero, a beautiful young girl, attracted worldwide attention with her every move.

And then the Hero announced to the world: "I will return to my master, Win Bird."

This is the story of a boy who, from being a dropout "Perennial Knight Cadet," somehow class-changed into "the Hero's Master."
