I am Adjutant is the unnamed second-in-command of the Delmo Corps, and after Hagen's death she became second-in-command of the entire Delmo Corps. She is a young woman with short dark blue hair. She usually wears her White Delmo uniform, but during the events of Trial 6 is also seen wearing a pilot's attire and civilian clothes with a similar motif to her uniform. She is knocked out in an unseen manner by Gust early in the story, and throughout the rest of the first half she is seen next to her fellow White Delmo and lover, the Delmo Commander, operating the ship.

She and the Delmo Commander attack Aika together at the climax of Trial 6, fighting as 1 with very coordinated attacks. They manage to land a hard blow on Aika with a combined flying kick which literally sends her flying several meters into a wall. When they seem to be on the verge of victory, they make the mistake of repeating the same attack once more.

This time, Aika is prepared and counters with a brilliant flying kick of her own, a maneuver which takes both Delmo girls by surprise and leaves them defenseless as she lands two devastating blows on their foreheads with the back of her high heels. The sheer force of the impact sends the two lovers flying on separate directions as they scream in anguish. these delmos are evil and support female supremacy! they serve Rudolf Hagen and Neena Hagen is his biological sister or simply another test tube baby with no blood relation.
