The Blue Knight once said that not all demons are what they are because they deserve it and some of them, despite divine punishment, will continue to serve to the heaven.
but is it really correct to murder them because they are demons? Or does the heart really matter despite the sin of being a demon?
That is a decision that you will make in Kaiser X
Will you kill all of them? Or will you save the demons and humans who deserve to live?
The guardian is one of those good-hearted demons, and this player made a decision.
make your decisions wisely.
