Voice Actress: Julie Ann Taylor (https://www.youtube.com/watch?v=SjBFrvSTZ4c)

Kokonoe is Tager's superior at Sector Seven, Roy (who became Arakune) and Litchi's former employer and Jubei and Nine's daughter. She is a half-beastkin, a child of two of the Six Heroes, though she shows unexplained disdain for this fact, supposedly "staying angry for weeks" when Jubei is mentioned. 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's displayed and perceived as cranky most of the time, though she harbors much sadness and rage beneath her usual facade. Her true mission is to kill Terumi whom she held a grudge against due to him supposedly killing her mother which somehow led her mother's downfall as well. Due to the fact that Terumi grows stronger the more one hates him, however, she has learned to temper her hatred enough that during one of her arcade scenarios, Terumi is utterly powerless against her. Kokonoe is a powerful magic user herself, but dislikes using it and prefers to use her inventions in combat. After assisting Ragna from Continuum Shift and onwards, she would later seal away Azrael thanks Jin and Kagura at the end of the series and still acts as Tager's superior, then now also Bullet's too after the mercenary was ready to learn the truth and reconcile with his cybernized captain. With her Drive, Graviton, Kokonoe uses a small machine that pulls her opponent towards it.

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-beastman; 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 BlazBlue: Chrono Phantasma.

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. She was also willing to use an alternative method to activating the Lynchpin where Celica wasn’t sacrificed despite her being merely a clone and even took the initiative to create the Ex Machina: Minerva so she could defend herself. 

Tager has described Kokonoe as being selfish, foul-mouthed, having an addiction to Silvervine candy and having the belief that the entire world focuses on her and her alone. Overall, Tager gives a very negative outlook on her when first describing Kokonoe to Noel Vermillion; however, at the end of his “frank opinions” on his superior, he states that she is actually a very kind and good person, something that Makoto Nanaya immediately calls out on, calling it contradictory to his previous sentiments. Her anti-social behavior and lack of outdoor activity implies that Kokonoe is a Hikikomori.

Lotte Carmine also introduces his opinions about Kokonoe to Litchi Faye Ling when they first met. Despite his numerous complaints about her lack of ability to congratulate people, he points out how she possesses the trait of not paying much attention to detail; but compliments her abilities as a scientist.
