The Holy Court said that he was an incomplete failure and threw him from the abyss of the sea of clouds.
Lucas, the leader of the Black Wings of the Abyss, picked up this palm-sized little fur ball that was afraid of the dark.
"The abyss has not raised any living creatures for thousands of years. Now that we have picked them up, let's keep them."
From then on, there was a little angel in the abyss who could "chirp", plant flowers, and put the broken halo back together bit by bit.
The poisonous Lord of the Abyss acts as his backer, the gentle military counselor teaches him how to read people's hearts, the violent warrior secretly sews his boots, the alchemist granny chases milk paste, and the librarian accompanies him to look through ancient books - they are waiting for a legend to grow up.
He is an abandoned failure. It is also the first and last wing between the two worlds.
