Despite being stripped of his posts and warned of the death penalty, Charlie demands the coffin be opened, accusing the authorities of breaking their promise to revive his sister after centuries of guarding the Demon-Sealing Tower. Officials insist the coffin cannot be opened without the Queen's order and deny Charlie's claims that the Demon-Sealing Tower is broken and Soul Beasts are about to be unleashed. Tensions escalate as guards move to seize Charlie, leaving his mission hanging in the balance.
