Kuroka Toujou

At first, Kuroka was shown to be rather malicious, with her aura described as being more "outright evil" when compared to the "vice" of Azazel's. In the past, she was said to have murdered her previous master, as she was unable to gain control over her Senjutsu, and was driven mad as a result. This initially seemed true, with her first appearance having her declare her intention to kill Rias, Issei, and her sister after the latter refused her, and that was after using poison to weaken Koneko and Rias, all after commenting on her intention to use Koneko as "a piece under my control". However, she later claimed that vicious display was just her "going with the mood". Under normal circumstances, Kuroka is rather playful, nonchalant, and simple-minded, simply enjoying teasing people. She's rather vulgar, often using her beauty and sensuousness as a weapon among her arsenal of teasing others. Above all else, despite her mischievous nature, she can be a kind and compassionate woman who loves Koneko more than anything, wanting peace more than anyone. To raise Koneko after becoming orphans, Kuroka agreed to become a reincarnated Devil. She murdered her former Master to protect her younger sister from him, though it meant she'd become labeled as a criminal and continued to play that part. However, Kuroka often has a hard time showing this side of herself, often opting to tease her younger sister instead. She expressed an interest in having strong children. Her reason being because she wanted her species, the Nekoshou, to bloom once again, their kind being inherently rare. Adding to her feline personality, Kuroka often ends her sentences with "Nya" (にゃ), mimicking a cat's meow.

Appearance: Kuroka is a beautiful young woman with a voluptuous figure, long black hair with split bangs, and hazel-gold eyes with cat-like pupils. Her body measurements are [B99-W56-H91 cm] [B39-W23-H36 in]; height is 161 cm (5 feet 3 inches) and body weight is [49 kg].

The kimono features a red interior and it is open at her shoulders, giving view to her large breasts which rival those of Rias and riva those of Akeno in terms of size. Her hips outclass Rias Gremory in size. In her Nekomata form, which she is in all the time, she grows a pair of black cat ears and two black tails.
