Ren Hoshino is sixteen, an orphan, and the first person in the district's records to show no mana at all. After a public failure that leaves him laughed at and spat on, he stumbles on a dying old man with a glowing red core in his mouth. He swallows it. Now a voice lives in his head, and it wants him strong. To earn a second chance, Ren has made a deal that means death if he fails.
