Chugong

“Chugong” (추공) is a pen name, not a legal name. It roughly translates to “clear autumn sky,” which is pretty poetic when you think about it. That’s all we officially know — the author of Solo Leveling has chosen to stay private, never publicly revealing their face, full name, or personal background.

Online databases sometimes list a name like Kisoryong Chu-Gong, but there’s zero confirmed source behind it. So, for all practical (and respectful) purposes — Chugong is the name that matters.
