The whole stupid point of this was to try and push Shin over the edge in one way or another. The whole "he's the most powerful mage alive. What would happen if he became a devil" plan. It's pretty much standard stuff for Shin for a while after. More money, alliance stuff, he solves a major mystery, more minor antagonist, more devils thinking how to deal with Shin, etc etc etc zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz....
