I feel like the Iris girl was selected as one of the apostles. When fighting the drake king we saw an image where the drake king was beaten by a beautiful girl with ebony hair, just like Iris. The drake king is only a thousand years old, how could someone live 3,000 years without divine intervention? I feel like she was promised something in return or fell into deep despair and was corrupted
I'm just here for a good time
