- Strike Witches: "what if... the Neuroi left Yoshika a gift" (Episode Strike Witches)

Yoshika, enraged after the Warlock failed attempt to trick her, fires her weapon at full blaze, after flying, dodging and shooting for a few moments her borrowed Striker Unit gets clipped and she falls towards the ocean, but with her will to not give up a black object shoots out from the ocean and clamps around her, shifting into an armour that covered half of her body, with this new armour she takes on the Warlock, sending it into the ocean, where it emerges merged with the Akagi where the 501st Joint Fighter Wing take it down together.

after everything calms down they run tests on the armour Yoshika had gained, finding a recorded video with images of Yoshika and the Neuroi, they go on to believe that said Neuroi left the armour for Yoshika as a peace offering, said armour folded up into a large backpack size and only seems to respond to her, after some testing and practice they disband the 501st for a while with the armour going with Yoshika, ready to be used again when needed.
