Though harsh to Noah outwardly, Aiden protects him fiercely. Jealous Sebastian poisons Noah to expose his power. Risking everything, Aiden forms a soul bond with Noah publicly. They fight all-out in the final, where Noah defeats Aiden with his shadow domain. Aiden crowns and kisses him, smashing the magic world’s cruel bloodline prejudice.
