Teito Klein is a former slave sent to attend the Barsburg Empire's military academy thanks to his ability to use Zaiphon (a type of magic). The ability is rare, and thus highly prized. Teito is an amnesiac and doesn't remember anything of his origins -- what he does learn of his past comes from his recurring and often traumatizing dreams.

After a year at the academy, the graduation exam comes along; it's notoriously difficult, with a pass rate of only twenty in five hundred. Teito and his only friend, Mikage, pass easily. That night, in their shared dorm room, they each promise to help the other at any cost. The next day, Teito is delivering papers to a professor when he overhears his name. He stops to listen, and realizes that the speaker, a man named Ayanami, is the man who killed his father in his dreams. Teito is found eavesdropping and tries to attack his father's murderer. He's quickly brought down by one of Ayanami's subordinates and sent to prison. Mikage comes to help him escape, only to find out that Teito managed to fight past the guards by himself. The two flee the building, and when they're caught on a balcony, Teito pretends that he's holding Mikage hostage. He threatens loudly to kill him, but to Mikage he whispers, "We'll always be best friends, right?" After Mikage replies "Of course," Teito jumps off the balcony onto a waiting hawkzile (a kind of flying motorcycle) to escape.

Ayanami notices Teito trying to escape and sends a Zaiphon attack after him, which Teito manages to partly deflect. The injury eventually weakens him and he loses control of his hawkzile, sending it crashing into another. Luckily for Teito, the man on the other hawkzile is a bishop in the nearby 7th District, and brings him to the church to recuperate. Since at this point Teito is in chains, the bishop, Frau, mistakes him for a slave and comments that if Teito had been a soldier in the Imperial army, he would have killed him immediately. Thanks to the law of "sanctuary", Teito can stay in the church without fear of the Empire or Ayanami.

It's later revealed that Teito carries the Eye of Mikhail, the powerful artifact that his home country, the Raggs Kingdom, was ransacked for. The tragic death of a loved one catapults him into his quest for revenge against the Barsburg Empire, and knowledge about his past, all while he gets caught up with the Gods, Verloren, and the 7 Ghosts.
