Digital-Galaxy
Mia Henderson enters Cross Academy, but this isn't the normal Cross Academy that you all knew. Now beside the Day Class and Night Class, there's a Golden Class. The Golden Class is split in two, Golden Day Class and Golden Night Class, and these Golden Classes are even more suspicious than the Night Class. On Mia's first day in the town, she meets and befriends a Golden Night Class student named Allison Woods. As time goes on, questions arise about these Golden Classes, as well as the night Class. Mia takes it upon herself to investigate both. What she discovers instead, is her own origin.
They call themselves the Golden Knights of the Light and Night.
(I rewrote this story since the first time I didn't get very far. So the first chapter after this description is the old version. You can skip it. I just kept it up for comparison's sake.)
