Black Blood's AwakeningEpisode 25

Arion Black was prophesied at birth as the "Anti-Magic Vessel"—the final piece to the Demon Lord's conquest. His parents died sealing the Demon Lord and entrusted him to Headmaster White, who abandoned eight-year-old Arion in the slums out of jealousy. Ten years later, the Queen summons all noble heirs back to the Academy. Arion returns, scorned by all—but nobody knows the seal on his power is crumbling. Anti-magic is awakening. And the Demon Lord's prison is cracking open.
