The action sequences move like they're choreographed by someone who actually understands how bodies work in space. The story demands you keep up, rewards you for paying attention, but doesn't pretend it's simpler than it is. Tori is trying to save someone he loves while entire nations reshape themselves around him, and the show treats both the small moment and the world-breaking one with the same ferocious energy.

Using the opening the Mikawa Conflict gives them, Tori and his classmates at Ariadust Academy try to rescue Horizon, the revived heir to the Mikawa throne, from the Testament Union. Having claimed sovereignty over Mikawa, the flying city-ship Musashi heads for the Floating Island England in search of refuge, where talks with its hesitant ruler, the Fairy Queen, open on a hopeful note. That calm soon breaks. Tres España is gathering an armada to strike the British, and Musashi lands in the middle of a restaging of the 1588 Spanish Armada invasion. The students must rely on their individual abilities to win allies while shielding Horizon from the world powers now set against them. Meanwhile her quest to recover her emotions nears its peak, and the secret of the Armor of Deadly Sins comes to light as the reenactment of the history in the Testament goes on. The second season of this action fantasy is thirteen episodes long.
