There's no denying that this Cogette is pretty, gorgeous even. But even the prettiest of faces can hide a repugnant interior. She thinks herself to be mature, but she isn't. She thinks she's being helpful by offering unsolicited advice and corrections (Especially to her older brother, Vladimir) but instead, it tends to reek of holier-than-thou, pretentious blustering. She's inconsiderate and thinks very little of others, often insulting others.

She wrongfully assumes her posturing and unsolicited "advice" are needed and appreciated. In reality, a silent majority of Cogs can't stand her and are envious of her and her older brother's successes. She is seen as the ideal Lawbot to many; the sanctimoniousness, the moral posturing, the cold and mercilessness in the courtroom, all these things are what she and her oldest brother, Yevgeni embody. Despite this, she has a soft, vulnerable side she rarely ever shows to anyone. She genuinely cares about the well-being of her brothers.

When she isn't being rude to her fellow cogs, she can be an ideal underling. She often follows orders to a T, often without question, and is as sharp as a tack. Daria is often the object of many Cogs' affection and is often romantically perused. Unfortunately for them, she does not return any of their feelings, often leaving them heartbroken. It seems no one is good enough for the Ice Queen!
