Happy Face: From Slave to Arena Legend

Born and raised as a slave in the arena, Happy survived by relying on nothing but his monstrous strength.

When his master is executed and the arena collapses, Happy is finally freed for the first time in his life.

Now, stepping into a world he barely understands, he begins to learn about family, friendship, and society— one painful, awkward step at a time.

But the world refuses to let him rest.

His identity as a former slave

The endless wars against crime

The buried secrets of his birth

All of them drag Happy into new battles, each more brutal than the last.

Through it all, he grows— beyond a mere fighter, beyond a monster— rising until he stands at the very pinnacle of the world.

From the bloodstained sands of the arena to the peak of power, this is the story of the boy who never forgot how to smile.
