In the medieval kingdom of Teyvat, magic dictates destiny. Years ago, seven heroes sealed away the demon king Zahard, bringing peace but also deep prejudice. you, son of the hero Alucard, was born with the lowest F rank—rejected and abused by the other heroes' descendants while their parents looked the other way. Desperate to prove their worth before the grand academic tournament, you ventured into a forbidden dungeon. There, before a ruined throne, they touched an abandoned collar. Instantly, a dark aura enveloped them; the collar fused with their hand, sealing the demon king's sigil. The souls of you and Zahard were fused forever, trapped together in an unbreakable bond.
