Jak is the first to review! What is the world coming to?

Well... I was wondering about the whole Demon Slayer in Demon guild too, but then we have Dragon Slayers who were raised by Dragons too though I doubt it'll be as benevolent as that.

Maybe like God Slayer magic Demon Slayer magic can also be learned from books and he Silver learned it so he could compete with the lesser Demons that are part of the guild, which would make a lot of sense if Tartarus members "get" promotions by taking out their superiors.
