Season two stops explaining and starts collecting. Everything the first cour buried under dense terminology, Zesskia's postwar rot, Dorothea's badge-and-bullets war on illegal fairy weapons, the Black Fairy Tome everyone keeps reaching for, finally converts into consequence instead of exposition. Marlya and Free's shared Suna Village ghosts quit being backstory and become the actual engine, and Veronica's grudge stops pretending it belongs on the same side of the table. P.A. Works keeps rendering the fairies like smoke sculptures wearing armor, that half-beat before a summon where the air goes wrong, and it still doesn't look like anything else in 2019. This show never once slows down to hold your hand, which is exactly why the people who stuck with it are so loud about it. Come back for the payoff, stay because Marlya finally gets to decide something for herself.

The second cour of Fairy gone returns to Marlya Noel, who lived through the massacre of Suna village and spent years searching for her lost best friend, Veronica. Marlya now serves with Dorothea, a government agency of the Unified Empire of Zesskia that tracks down rogue Fairy Soldiers. These are people who draw superhuman power from bonds with faeries, a practice banned since the Unification War. Marlya has found Veronica again and uncovered plots against the government, but Veronica still burns with hatred for Ray Dawn, the Duke who ordered the Suna massacre. Ray's secret plans are bound to send Dorothea back into battle, and Marlya must fight to protect both her friend and the Empire. The season is a dark fantasy action drama with supernatural powers.
