Loretta joined the rest of the Blaze Brigade in fighting a battle against the Mars People to increase their division's reputation within the Rebel Army. The two were joined by new recruit Norah, though Loretta was initially skeptical of Norah's capabilities due to her shyness. However, Loretta later discovers her true personality when she finds Norah battling Marty. She then drags Norah away to safety before Grazia burns the whole place down.
Loretta showed up alongside her commander and Norah to confront the Invader Bloom Metzelei when she began attacking the Blaze Brigade soldiers. Before they could fight Bloom, Fedeln Metzelei appeared and annoyed Bloom into leaving.
