Maypia Alexymetalia

She is a "Class A" spy (who carries suitable business cards) employed by the government to retrieve information on Lagu by infiltrating Hagen's army dressed as a black Delmo. She runs into Rion and ends up following her.

After having been abandoned by her employers and her subsequent rescue by Aika and her friends, she went freelance. She reappears in episode 7, where she joins Rion and company in their assault on the Delmo base.
