Legend has it that there is such a door that can grant all your wishes.
It exists everywhere,
Some people say it is at the junction of heaven and earth.
Some people say that it exists at the alternation of night and day,
Some people even say that this sealed door can move. It will appear next to you for a while, and it will appear in your dream and memory for a while.
In fact, no one knows what lies behind this magical door or where it came from.
The story begins with an ordinary girl who opened a door by mistake and caused confusion in her own memory. After finally passing through the door, what appeared in front of her was an academy at the junction of heaven and earth - the Supernatural Academy. In this unusual academy, there are all kinds of people, all kinds of tasks, and everything is somehow related to the legendary door.
(In short, this is the story of a group of people and things revolving around a door, pursuing the legendary door forever)
