An ordinary college student accidentally picked up a unique coin on the road. After going to bed that night, he was involved in a strange world.
"Hello, system 0411 is at your service"
In the first world, there is a Black Rose Castle. The owner of the castle has two young and beautiful daughters. As the second daughter, you enter a strange academy. The academy only has one day of classes every month, but it will issue strange tasks at strange times. They are all carried out in a black swan garden perched on a high mountain. Every time you come back, there will be a few people missing, but no one remembers them...
They call you Second Miss, but you know, you are just a little boy who came out of an orphanage. Why did you suddenly become a distinguished Second Miss? Who makes the weird noises in the castle every full moon night? Who is that sister who is widely praised but has never met you? Every time someone goes missing, why is it that no one knows?
