Three hundred years ago, the Shadowcat tribe betrayed the coalition forces and joined the Demon God. The entire tribe was expelled from the civilized territory, and the Holy See of the Temple continued to hunt them for three hundred years.
Three hundred years later, the human princess Lucia Edmund, who awakened the blood of the Word Spirit, picked up a dying black cat on the night she entered Silver Star Academy. The left ear is missing, the tip of the tail is white, and the body is covered in bruises.
She didn't know that this cat would turn into a boy on a full moon night, nor that he was the legendary "Moon Shadow Elvis", nor that the mark in his body was the key to the Vatican's high priest's plan to resurrect the demon god.
When the Holy See's hunt and the undercurrent within the imperial power surged towards Silver Star Academy at the same time, when three hundred years of stigma and taboo bloodlines were revealed one by one, one person and one cat stood at the junction of the crown and the abyss.
She wanted to be on top of the throne, and he just wanted her to be safe. But someone told them: to pick up the crown, you must first pass through the shadow.
