Fate can vibrate

The world that used to be normal got changed by a cataclysmic event called the second falling. And a consequence of it was that people gained super natural abilities more well-known now as powers. Every year, the top teaching institution called Grandviville hosts a free full scholarship exam that has a 0.0001% passing rate. Yet that doesn't stop millions of people each year from participating. And Saif was no exception. A boy with the power of being able to manifest or contain vibrations. But when he took the test, he didn't know there was a second page on the written exam, and got a D- on the practical exam. Yet somehow, he got an acceptance letter to enter the S class of Grandviville. The only twist is, that class is reserved for the 11 families. The families that rule over the world using their powers. Either because they are the strongest, or the most influential, or the best at control. But he wasn't the only one to enter this year's S class, so what game is the 11 families play at here? And how will he survive during his years in Grandviville?
