It puts you on latrine duty at the end of the world. The 108th Guard Squad in Aomori is where the army files the kids who couldn't cut it for the elite units up in Hokkaido, and the show is honest enough to let that sting sit for whole episodes at a time. You get rusted-out walking tanks, supply lines that barely exist, and an enemy closing on the empire while these teenagers argue about chores, crushes and who's cooking. That slow rural drift is the point: the war shows up on someone else's schedule, and the drama is whether anyone here still believes they're going home. Fans who came in expecting the 5121st and Gunparade March's cast to walk back on screen had to make peace with a whole new set of strangers. Stay for the ones who stop calling this place a punishment.

The 108th Guard Squad is stationed in Aomori, a poorly equipped unit with little military standing that many regard as a place for pilots who fell short of the elite units in Hokkaido. Ishida Sara, fresh from the Toshitake staff training school in Tokyo, arrives to lead the flight troop of its 4th division. None of her troops has ever faced the enemy in real combat, and at least one of them does not want her there. The setting is an alternate history in which an alien race called the Genju descended on Earth at the close of World War II and has been pushing humanity back ever since. When the Genju appear again, the 4th division is ordered to sortie, and young pilots who dreamed of returning home are dragged into a war they never wanted. The show is a mecha drama with romance and slice-of-life elements.
