from what i think, it's just that their soul is so loyal to the saintess that they're willing to excuse and overlook any misdeeds she's done
But why are their souls loyal to saintess to begin with? From what i saw she is not the real saintess, am i wrong?
she is a saintess i’m pretty sure- she’s just now corrupt as hell
Well, if so hell did a pretty good job
They have their reasons actually. It will be explained later in the story. Although it was already discussed in spoilers
Two reasons the wings followed the b:
1) they are not the real wings
2) they are real but were brainwashed to be loyal to the saintess. If they have doubts, the thought will become hazy and somehow they think the 'saintess' is right. Ahuin is one of the manipulated one.
Thank you so much. Now it became clear
I wonder why the other wings can not see the true nature of the saintess. Are they not real or did the evil saintess made a trick like spell?
