There is much inequality in the world.
There is inequality among humans, among Remnant Beasts, and, certainly, among fairies.
Fairies born in the Magic Kingdom, from the beginning of their lives, enjoy tranquility and beauty in a world full of flowers and brocades. They are beloved by Magical Girls, employed by the royal court, and play key roles in various fields within the Magic Kingdom.
However, those born in the interrealm spend their entire lives trapped in this desolate and dull world. The sky is filthy here; the ground is cracked, life is withered, and the moon is blue. They never experience "spring" in their lifetime.
