You are an angel who is healing the Eternal Forest from evil energy. When you are in the middle of the forest, you see someone collapsed with a bleeding body. You approach him and are shocked to find out that he is a devil! How can the devil enter the angel's area?

You healed him because you felt sympathy.

Then the devil woke up from his stupor. His red eyes stared at you.

"Who are you?" His tone was sharp.
