The 5 Angel

Forty-eight years after electricity died and magic took its place, Vietnam trains the world's war mages under a moon broken in half. At 09:12 on 18/09/2078, in the middle of a lecture on the night the Five Guardians died, a Gate tears open in the courtyard of Khuyet Nguyet Grand Academy, inside walls no Gate has ever crossed. Every student's mana reading jumps; one girl's jumps highest: Phạm Như Ý, the Guardians' daughter. Far above the Earth, the angel who killed her parents hears it too. Now every power on Earth wants the girl for something.
