Her cloneblade armor is purple and red.
She appears much older than she truly is which suggests that the sisters age rapidly. She is actually younger than Rihoko. She has an obsession for cats and dogs plush stuffed animals.
Maria undergoes many changes throughout the series. She starts out as a hyper, mentally unstable adolescent with an extreme inferiority complex. While extremely strong and dangerous, she is little more than an insecure child desperate for attention and a mother to call her own. This changes when her actual mother, Reina Soho, rejects her. After killing Reina in a rage, her personality becomes almost catatonic. She also changes her appearance to match the deceased Reina's.
After hearing of Furumizu's plans to use her as a surrogate mother for his "perfect" clone, her disgust transforms her into a megalomaniacal psychopath who seeks power at all costs.
She kills Furumizu and seizes control of the NswF. She pledges to transform the NswF into an army that will secure power for herself as well as the Neogene "chosen ones".
In truth, however, Maria is the leader of the organization in name only. With no clear goal other than to obtain power at all costs, Maria becomes even more secretive and reclusive than her late "father". With the exception of Aoi, cloneblades such as Asagi view her as an insecure child trying to "act tough". As Maria drifts aimlessly, Nishida effectively runs the entire organization and continues to use its resources to hunt for the Witchblade.
