The Symphogear cast stops saving the world and just lives in it for four episodes. You get the characters you spent a season rooting for, stripped of crisis mode, doing genuinely stupid things together. It's the reward for surviving the heavy stuff, compressed into shorts that know exactly how long they need to exist.
Symphogear AXZ Omake is a set of four original short specials from 2017 that redraw the franchise's characters in a cute super-deformed art style. The episodes were packaged with the home video release of Symphogear AXZ, included with the Blu-ray and DVD volumes 3 through 6. The genres pair comedy and slice-of-life with action, music, magical girl and science fiction elements, making for a lighter bonus take on the cast.
