The inspiration comes from an unrealistic fantasy of mine. If there really are monsters in this world, what kind of life should they live.
Do they feel they are out of tune with the world? Do they also need to go to work to earn money to support their families? What is their relationship with humans? Can you tell your deepest secrets to the people closest to you, even if you risk hurting each other?
Purpose: Anti-discrimination, don't hurt others, stick to your own path.
