The man in black, without the need to even think about it, was also most definitely more powerful than Venera herself. Furthermore, these birds were not real at all.
They were just living things created by her in this dream, a product of illusion, so why is the man in black so passive when going against them? Why is he just so innocent, so generous, and so kindhearted to these birds that were not even real?
If it were her... Well, animals have always treated her very kindly, so there would be no such case anytime in the future. She was just the exact opposite of the Ruler of the Abyss, who seemed to be the natural nemesis of all. At least she had never been hurt or wounded by any kind of animal, whether small or large, before.
