One-Punch Man from the Start: Sign In and Claim Divine Skills

He transmigrates to the world of One-Punch Man and becomes King, the strongest man on Earth. From the start, he awakens a God-tier Sign-in System. He signs in at the Hero Association and receives rewards: top-tier Conqueror's Haki, the Golden Light Mantra, and the Five Thunder Rites!

From then on, he can sign in every twenty-four hours and claim one world-shaking, god-tier reward after another.

Bang: King's title as the strongest man is beyond question. His martial arts are far superior to mine!

Atomic Samurai: I always thought my swordsmanship had reached the pinnacle, but it wasn't until King drew his sword that I realized how weak I was.

Tatsumaki: If anyone in this world is stronger than me, it has to be King.

Saitama: The only rival I've ever had in my life. He's so powerful it's hard to believe.

Then, one day:

Ding! The Hyperdimensional Chat Group invites you to join.

"Thanks, but no thanks. I'm the strongest on Earth. I can blow up stars with a casual move. That's just basic stuff, don't make a big deal of it."
