I, KING, Am Truly the Strongest on Earth!

When the “King Engine” roars, it’s the day monsters fall!

After transmigrating into the world of One-Punch Man as KING, the S-Class hero who’s rumored to be the strongest man alive because he always shows up after the monsters have been defeated and is scared out of his wits?

No! In this life, I don’t want an undeserved reputation!

[Ding! The Strongest Hero System has been activated! Make monsters afraid, and you can extract attribute points without limit!]

The “strongest man on Earth” is no longer a misunderstanding. This time, he’s the real deal!

Vaccine Man? Crushed with one finger!

Boros? Sorry, your Collapsing Star Roaring Cannon can’t even get through my defenses!

Saitama: “KING, you really are strong. You’ve completely stolen my thunder…”

Tatsumaki: “That shut-in… How can he possibly be this strong?! (Blushing)”

This is the story of a true king, crushing anyone who dares challenge him with absolute power and rising from seventh place in S-Class to the peak of the universe! How lonely it is to be invincible!
