Galaxy Angel—The primary mission of the Angel Brigade, a branch of the Transvaal Empire’s military, is searching for relics known as “Lost Technology.” The problem is that no one actually knows what Lost Technology is, so they’re instead relegated to doing various menial tasks. Although the Angel Brigade is supposed to be saving the galaxy one planet at a time, the newest member Milfeulle and the other four members—Ranpha, Mint, Forte, and Vanilla—usually find themselves getting into various misadventures, creating one hilarious situation after another for everyone involved.
