I am Black Delmo Leader is the unnamed leader of the Black Delmo. Black Delmo Leader is a young woman with short purple hair with curled ends. She is seen in her Black Delmo uniform. She is first seen leading a small attack on Aika Sumeragi and Gust Turbulence. However the attempt fails and her entire unit of Black Delmo ends up soundly defeated. When she realizes Neena Hagen is present, she inmediately gets on all fours and tries to apologize for her squadron's failure.

However, Neena is not interested in her excuses and brutally kicks her between her breasts just as she is trying to make amends. The poor girls is caught entirely by surprise, and her wholy body jerks as she takes in the impact, breasts bouncing upwards while she releases a sad moan. In shock but still standing, the Delmo starts blushing furiously as drool emerges form her wide open mouth, and tears can be seen falling from her eyes. Her eyes then go vacant and begin to close, a clear sign she's out for good, just as her upper body starts to crumble to the floor. As her torso plummets to the ground, the movement pulls her short skirt upwards, revealing the few parts of her butt which the miniature cloth still covered. The lower body then collapses as well, the big round butt of the girl jiggling as it hits the floor, legs wide open and panties exposed.

Neena then grabs the girl by her hair and mercilessly lifts her up, unceremoniously throwing the Delmo's unconscious body over her left shoulder, ass upfront. This makes the unfortunate leader the first girl to be draped over shoulder. She then gives her butt a tight slap as she tries to use her as an example to scare Aika off her brother's trail.

Later she and the other Black Delmo are seen being punished with spanking by White Delmo. She is seen later in Trial 4 being attacked by Aika and used as a hostage. Aika tie her hands together behind her back and force her to march, as they walk pass the other Black Delmos in shock that the position she's in, leaving her humiliated. Moments l
