The academy where talents from all corners of the continent gather.
Ian Percus, a third-year student there, receives a letter one day from seven years in the future.
It speaks of how he, once a mere second son of a rural viscount, becomes a hero in the future,
And carries a chilling warning: "If the future is not protected, the world will perish."
At first, he tries to laugh it off as a prank,
But he soon realizes that his memories of the entire past week are gone,
And every action he took during that time is shrouded in mystery.
To make matters worse, his childhood friend Emma is attacked just as the letter foretold,
Convincing Ian that this is far more than just a simple love letter.
As he begins to track down the clues in the letter one by one,
Ian eventually plunges into the fight to save the world and protect the future that lies ahead...
