One-Punch Man: King of the Sky

He is Test Subject 77, a flying experiment who escaped from the House of Evolution.

In the eyes of ordinary people, he is a hero who fell from the sky.

In the eyes of other heroes, he is the mightiest king in the heavens.

Mr. King, the strongest man on the planet, once said: “Flyman's power in the sky is just like mine on the ground. He is invincible.”

This is the story of the King of the Sky.
