Ep. 99: Asta and Zora rescue Mereoleona from Rhya’s attack while Mimosa faces capture.

Rhya reveals Asta’s Grimoire belonged to Licht, prompting Mereoleona to engage him. Asta attempts to assist but is intercepted by Zora. Mereoleona suffers severe injuries from Rhya and unleashes Purgatory, a spell causing blue flames that incapacitates her while failing to defeat the elves. As the elves prepare a team spell to kill her, Asta and Zora arrive. Asta had devised a plan where Zora traps five spells, doubling their power, shoots them at Asta, and deflects them back to quadruple the force. This explosion enables their escape, though Rhya uses a portal to seize Asta. Meanwhile, Mimosa remains the only unpossessed human after Yuno, Klaus, and Hamon are taken over. She is captured just as Rhya drops Asta into the room, where he discovers Yuno has become an enemy.
