“A man once called the strongest in the world.
The heavyweight champion of the world’s largest martial arts league.
Choi Hyun-seok, who was once the mightiest man, begins a new life as a hero in another world after his death.

‘A hero who monopolizes wealth, fame, and beautiful women!’

Dreaming of a glorious future, he arrives in the other world, only to encounter a monstrous beast with a head one size larger than his own.
The monster, a high-ranking officer of the Demon King’s army, asked:

‘Hero? Are you the so-called hero?’
‘Uh… I guess I’m the hero…?’

And so, hell began.”
