How to Survive as the Demon King

In a world where 100 Earthlings are summoned and trained as heroes to stop the Demon King:

"Whoa, amazing! I got an A-rank aptitude!"

"Really? I only got C-rank..."

"I’m a ‘Pyromancer.’ This is S-rank aptitude. Pretty awesome, right?"

"Looks good. I got S-rank ‘Diamond Guardian’ too."

Excited voices reached his ears.

Seo Woojin checked his own status window with gloomy eyes.

====================

■ Name: Seo Woojin

■ Job Aptitude: Demon King [Unmeasurable]

■ Level: 1

■ Skill: ??? [Passive]

====================

When he looked up, a huge banner hanging before him came into view.

『Welcome, otherworld heroes who answered the summons to stop the 8th Demon King invasion.』

Something sparkling leaked from Seo Woojin’s eyes.

"Ah, I’m fucked."
