I played through the demo, and made different choices with the Jorogumo. One time I exorcised her, the other time, I spared her. Both times I became an onmyoji. Do you become an onmyoji no matter what you do?
Also, is it possible for the MC to be a friend to all youkai, or simply prefer youkai to humans? I think my MC, after the first mission, would end up going in that direction.
