They serve as an army for the show's main villain Rudolf Hagen, as well as his sister Neena Hagen. Their roles include battling the Hagen's enemies, whether that is via fist fighting or with guns, and they also operate different aspects of Rudolf's ship.
The Delmo army is made up of beautiful young women wearing incredibly short skirts and high heels that show off their long legs. There are 5 different ranks of Delmo, all of which have different roles and outfits, they are:
White Delmos (ホワイトデルモ)Edit
The highest ranking Delmos. Their uniforms consist of white tops, dark blue miniskirts and white high heels. They are the officers of the ship and ensure that the ship operates smoothly.
Their leader is an unnamed, green haired woman, she is the highest ranked member of the Delmo Army, and when both Rudolf and Neena die midway through the series she takes over as the boss, and authorises a revenge plot against Aika and her friends. She is a lesbian and is in a relationship with her second in command.
Golden Delmos (ゴールデンデルモ)Edit
The second highest ranking Delmos. Their uniforms consist of an all gold top and miniskirt combo as well as golden high heels. They are responsible for carrying out Special Ops missions.
Blue Delmos (青デルモ)Edit
The third highest ranking Delmos. Their uniforms consist of an all blue top and miniskirt combo as well as blue high heels. They are elite infantry class and carry assault rifles, their roles consist of protecting the ship from dangers as well as piloting.
Black Delmos (黒デルモ)Edit
The second lowest ranking Delmos. Their uniforms consist of an all black top and miniskirt combo, long white tights and black high heels. They are infantry class and carry out simple missions as well as ship administration. Unlike their senior blue class, they rely on battling with punches and kicks as opposed to using firearms. Most new recruits start out at this level. Failure doesn't seem to be tolerated well by their superiors, as Neena Hagen and the White Delmos are seen physically disciplining them if they fail.
Pink Delmos (ピンクデルモ)Edit
The lowest ranking Delmos. Their uniforms consist of an all pink top and miniskirt combo as well as pink high heels and a pink hat. These Delmos are never seen engaging in physical combat, they are the mechanics and engineers of the ship, and are also seen driving tanks.
