"The World Tree is what made demons exist in this world..."
"What?! How can the World Tree be the reason for demons existing in our world? Are you saying that demons aren't natural beings of our world like everyone else?" Myne asked with a shocked expression.
"Well, although it is not a hundred percent true as you might be thinking, yup, overall, demons are indeed trouble created by the World Tree. Without it, there would be no demons in our world. But we also can't dare to do anything to the World Tree to deal with demons, as it is also our life source. That's why if someone tries to bring harm to the World Tree, it means that we Divine Beasts have to make a special trip to solve the trouble. Most of the time, it ends very brutally, with thousands upon thousands of people and animals losing their lives. The Elf Kingdom incident is a proper example of the meaning of Divine Beasts making their appearance for official matters."
