Legend says that whenever a hero's legacy appears, the cruel Demon King will descend at once.
He will personally kill the new hero, ensuring that no one can threaten his rule.
Kong Su didn't believe it.
At least, he didn't used to.
Not until the dazzling hero's mark shone brightly on the back of his hand,
while the little Demon King sat on top of him.
That's when he realized his life was about to be over.
But...
"I'll just take the hero's legacy for now~ I'll give it back later~"
"Huh?"
"Until then~ why don't you go cultivate immortality~"
"...What?"
Did something go wrong here or what...
