Inside Ren's soul realm the numerous incarnations were waiting for another visit from Santa Claus since it was already that time of year. The last time he came all of the incarnations who were hailed as the strongest of their era were caught by surprise.
So from then on, they gathered information about this so called Santa Claus from those incarnations that knew of the man. Basically what they gathered from the other incarnations was that Santa Claus was a type of sorcerer that has a list that designates who was naughty or nice. Supposedly this person called Santa rewards nice children with gifts and gives coal to naughty ones. When the incarnations that received coal learned of this they were quite upset.
"The f*ck how am I a naughty child! I saved my whole country before dying for my people!"
"That's nothing, I saved the whole world from an invasion but I'm still considered naughty? How the heck does this guy, grade people?!"
