Kotone Kotomine

"The nature is one. Everything is nature, all is nature... The animals, the green, the peak of the tallest mountain, the depths of the unknown abyss... Humans, Devils, Angels, fallen angels. From ash thy come, to ash thy shall return. All it's a circle, all ends, and from there it begins, to end again, to be born again, indefinitely, infinitely. The one rule of nature, the absolute comprehension of nature... That Kotomine Kotone has. She has total comprehension of nature thanks to her senjutsu, and that's why she can't tell the difference between anything. All is all, all is one for her, this nightmare of non-individuality and mixes. There's no names, faces, forms, colors, shapes, only nature, only nature. And from this world without individuality or segregations... She finds herself complete and utterly alone. And the boy who continue to speaks to the nekomata, who presented himself while she couldn't tell him apart from anything else in her eyes... Please answer this: do you really want to help the girl that with thou speak? If thy answer is yes, then... Please, kill me."

- Kotone to Ryuusei Kotone Kotomine(言峰琴音; Kotomine Kotone), also known as January 30(ジャニュリー・サーティー; Janyurī sātī) is a senior student in Kuoh academy and one of the remaining Nekoshous in the world, her real name being Byakuran(白蘭). She's one of the female protagonists and the first youkai Ryuusei Amano encountered in the DxD: Haremonogatari continuity.

A powerful nekoshou with unparalel talent, Kotone reached a level of control over senjutsu so absurd she no longer can't distinguish anything from anything, yearning for death of her hopeless situation before finding Ryuusei.

Appearance
Kotone is described by Ryuusei as a pretty girl with silver eyes, which he describes in being always with a distant stare, silver smooth hair and pale skin tone, with soft and stoic face structure and a pretty figure, curvilious with big breasts which Ryuusei always molests.

From her introduction, she's always wearing Kuoh's uniform of white lined shirt, magenta skirts and black corset-cape. According to Ryuusei, she's always wearing light blue panties. Due to her senjutsu, she also has no weight, being light as air according to him.

Personality
"Maybe this whole senjutsu is not exactly out of control, maybe I am really that aloof to the world."

- Kotone's conclusion

Kotone is a stoic and usually emotionless young woman. Having her senjutsu out of control ever since she can remember, Kotone developed an uncanny aloofness to the world around her since she can't distinguish between people, flavours, voices or even sensations, describing her world as a blank reality with no individuality, so much her sentences are described in either second or third person by yours truly. Despite this, she yearns for either contact with other living beings or death, since she's secretly desperate and paranoid, not trusting anyone and losing touch with even herself as a individual being. She initially fears that she might dissapear in case she ever lose her sense of self.

However, by the end of her arc, Kotone realizes that her vision of the world is not linked to her unpparallel power and senjutsu at all, and that she's simply extremely aloof to the world around her, not bothering to know new people or even taste anything different from her usual meals, living like this for so long she actually forgot about it. After falling in love with Ryuusei, Kotone begins to open herself more for him, while also teasing and questioning the affection other girls have for him as well. Ryuusei is the only person she calls by name.

Strangely enough, despite losing her sense for flavours, apparently Kotone's favorite drink is mocha fraps.

History
Not much is known about Kotone's past, only that she's one of the few nekoshous left in the world, who was adopted by a human couple and raised as her daughter. Having an extreme control over sage arts since birth, she started to see the world as blank and boring, in which in some part during her grown, she thought it was due to her sage arts, which almost drove her to suicide.

Powers & Abilities
Senjutsu - Senjutsu is the power to control the flow of life. By controlling the flow of ki, a person could strengthen physical bodies or cause vegetation around them to bloom or to wither. Knowing Senjutsu allows the reading of ki and auras and to spy on the target's state from afar. Kotone's control over her sage arts is so vast she apparently can easily control the weather around her, change her position much more like teleportation and even pass through solid matter. Moreover, her death might cause several natural disasters to occur due to her strong link with nature itself, much more like leylines from the kitsunes.

Stealth - Due to her control over her sage arts, Kotone is a master in hiding her presence altogether since she can simply blend her own existence within the nature itself.

Claws - Apparently, Kotone has retractable claws which can be used to scratch her enemies.
