Why They’re Called “Saja Boys”

Saja is from Korean stories. They’re like Korea’s version of the Grim Reaper; they take dead people’s souls to the afterlife. 

The group is called Saja Boys because they send demons away, just like how Saja takes souls from one place to another. It’s not just a random name; it actually means something from Korean culture.
