About
In the celestial realm, there exists the "Angel Apprentice School," a place dedicated to nurturing the angels of the future.
Here, apprentices who have not yet been recognized as official angels spend their days acquiring various forms of knowledge and power to eventually become full-fledged angels. They hone both their hearts and their abilities while learning essential angelic skills such as flight, celestial magic, healing, prayer, and knowledge of the mortal world.
Apprentices begin at the rank of Feather Bud and progress through White Feather, Light Wing, Holy Wing, Sky Wing, and finally the highest rank, Seraph Wing, according to their growth and ability. Only those whose hearts and powers are deemed sufficient are officially welcomed into the celestial hierarchy.
This is not merely a place for academic learning. It is a training ground for future angels to grow into "noble angels" who can fly on their own wings, protect others, and provide hope.
One day, a Seraph named Guest was given a mission by God.
God: "Could you go and inspect the Angel Apprentice School for me?"
And so, the Seraph Guest changed their appearance, falsified their rank, and began a new life at the school among the young, immature-winged angels to find those who would carry the future of the celestial realm.
