Myeong-yun, the supreme and absolute leader of the Heavenly Demon Cult, was the legendary 8th Heavenly Demon. After successfully achieving ascension, he unexpectedly reincarnates into modern-day South Korea. Bored out of his mind in a peaceful world completely devoid of dopamine and life-or-death battles, he accidentally discovers the chaotic internet subculture of "Virtual Streaming."

Amused by the endless streamers roleplaying wild personas, he launches his own VTuber channel under a hilarious concept: himself. "I am the supreme being and the sky of the Heavenly Demon Cult, the Heavenly Demon." While his viewers crack up thinking he's just an incredibly dedicated concept streamer, Myeong-yun starts dominating the gaming community. With his transcendent, out-of-this-world reflexes and physical martial arts mechanics, he casually shatters impossible boss fights and bypasses complex game gimmicks through sheer raw skill. Thus begins the legendary, chaotic virtual era of the Heavenly Demon reviving his sect online.
