Nanxi Noble High School is divided into two departments, Xibei Daytime Department and Xinan Evening Department. Legend has it that the student dragons in Xinan are full-fledged monsters without their heads or tails. Their bodies seem to carry a light that is beyond ordinary people, similar to the light of gods.
The night part of Xinan is actually another world, as unfathomable as the palace. It divides classes, there are god-like strong people and there are weak people who are vulnerable to a single blow.
Looking up at Xinan at night, the gears of destiny begin to turn under the mottled moonlight.
Legend has it that there is a kind of people who have terrible abilities, but also have a terrible curse. They are called "black cats".
Every black cat has another self, and no one listens to their story.
