Whether it's Dark Knight Austin or Dark Knight Wayne, they both stand with Wayne.
The Dark Saintess does too.
Even the Dark Goddess herself!
What can The Pope of the Dark Church do to fight them? Charge in and splatter everyone with blood?
"Even a Dark Knight can't act like this!"
Ivan, undaunted by the name of God-chosen Knight, was determined to avenge Wayne; so what if someone was a Dark Knight? Weren't they just another man and not Wayne's real father? Why shouldn't he seek justice for his daughter?
Even if the Dark Knight was Wayne's real father, he should still respect the purity of the Holy Maiden; otherwise, if the body through which the Goddess descends into the mortal world is sullied, the God-chosen Knight would also face calamity.
Ivan was not afraid at all; precisely because he was a Dark Knight, he should stand by him to uphold justice for the Holy Maiden.
