Kokonoe is a scientist at Sector Seven, and the daughter of Jubei and Nine, two of the Six Heroes, though she shows disdain for this fact, supposedly "staying angry for weeks" when Jubei is mentioned. The reason behind this is that Jubei left her in the care of the Novus Orbis Librarium for a great deal of her childhood, apparently not staying around to act as a father figure to her. She is became a playable character in Chronophantasma.
Kokonoe is a rather serious and cynical woman with no regard for emotions, and always strives for Tager to complete his missions without fail; however, she can on rare occasions be quite personable, mostly around her creations. She is displayed and perceived as cranky and foul-mouthed most of the time. She and Taokaka possess a few similar personality traits, something that most note as "more in common than they realize", due to their impatient nature and short attention span. She has some traits of her father and her mother. She also displays signs of being aware of the racism displayed to her heritage as a half-Beastkin; believing that people will show prejudice against her, it's for this reason that even her potential new students and apprentices aren't aware of her species, as displayed by Litchi in Chronophantasma.
However, as Celica points out, Kokonoe is a good person at heart. Without Litchi's knowledge, she became Arakune's Observer despite the risks entailed to prevent the Boundary from consuming him and is trying to figure out an effective solution for his depraved state. Also, she repeatedly shows that she will only resort to mass destruction in a worst-case scenario, preferring to minimize the casualties caused by her war against Terumi or not have any at all.
Despite being as capable on the battlefield as much as any character, Kokonoe doesn't participate in combat a great deal. Her forte comes in the form of her grand knowledge of magic and science and being the daughter of Konoe supplements this. While she has not shown any of her own creations, her prowess as a scientist is frightening, her alterations to organic and non-organic matter being second to none, even causing the normally ruthless and intimidating Hakumen to shudder at the promise of an 'upgrade' from her. Owing to her cat-like heritage, Kokonoe is known to possess cat-like reflexes, landing on all fours after falling from relatively great heights with no damage whatsoever.
