Gag webtoon about a very, VERY bored Demon King. Naver description: About a peaceful(?) Hell, a peacefully(?) BORED Demon King, and how the bored Demon King gets not-so-bored.
Such a good comic. It never took itself too seriously so I could easily get into it and not feel weary at any self-righteous or evil-for-the-sake-of-it antics.
There were also a lot of complicated characters and multiple story lines happening at once but it never got confusing (one perk of comics over movies is I have visual differences to help me figure out who is who so I don't need to flip back a few pages to know what's happening).
