Kirihime Natsuno (夏野 霧姫 Natsuno Kirihime) is the main female protagonist, a best-selling author under the pen-name Shinobu Akiyama (秋山 忍 Akiyama Shinobu), and the owner of Kazuhito Harumi after he was reborn as a dachshund dog.
Kirihime is a young, slender woman with red eyes, long dark hair and a straight-cut fringe that frames her face. She dons a black formal shirt and short black skirt secured by a belt. Over this, she wears a black coat that has red strings looped at the neck, hips and bottom. Kirihime also wears thigh high black high heel boots under them she wears long black stockings that reach up to her mid-thighs her ear's are also peirced wearing red stud earrings.
She secures her silver scissors in a red holster-like pouch that is strapped onto her left thighs above the stocking.
Kirihime is also often teased about her near flat chestness.
A "scary sadistic-flat chested girl", as mentioned by Kazuhito. She comes off rather scary to other people. She can get jealous really quick when other women are around Kazuhito and petting him and revering to him as "cute". But, despite her scary and sadistic personalities, she can be very considerate and delicate. This is best shown when Kazuhito came closer to her causing her to feel a little "uncomfortable" or whenever he told her something nice. Kazuhito's death, which came from protecting her, made her feel extremely guilty to the point of breaking into tears at the mere mention of it.
She first met him when they where sitting in a café. During that time a robber pulled out his guns to threaten the waiter. As the robber proceeded to Natsuno to shoot her, Kazuhito stepped between them. Unfortunately, when he tried to save her, he died only for him to be born again as a dog. After that she took him to her house where he lives the rest of his life there as a dog. At first she was just interested in him as a tool. She fell in love with him during that time where she tried to make it up to him for getting him killed. But Kazuhito never said he'd wanted revenge on the man who killed him, since he is still alive. So that it doesn't matter anymore. Afterwards, she broke down in tears. Whenever Kazuhito says a compliment without even knowing like "You're more important than tests" to Kirihime, she looks away; bright red and talks back with a higher pitch voice.
Madoka first resented her since she thought Natsuno was the one who took her brother away from her. She hates it when anyone beside her brother calls her "Sister". Especially, when Natsuno called her by that name. But as the story progressed, their relationship became better, to the point where Natsuno asked her to come with her and Kazuhito to the hot-spring.
