Synopsis
Yi Ji-Hyuk spent 1000 years in a medieval fantasy world — and he didn't spend them quietly. He lived as a full-on Demon King over there. Now he's back on modern-day Earth, and all he wants is a peaceful, low-effort life.
Too bad Earth didn't get the memo. Monsters are showing up, and a bunch of people with superpowers have stepped up to deal with them.
So what does a man who spent a millennium as the most terrifying being in another world do when his hometown starts having a monster problem?
