Kyōka Izumi

Kyouka Izumi (泉 鏡花,) is the newest member of the Armed Detective Company after defecting from the Port Mafia.

Appearance
Kyouka is a girl short in stature, with a frail-looking slender body. Her long hair is shown to be black, (indigo in the anime), with a notable ahoge; she wears a white hairband, and two hair clips with the shape of a flower that separates her hair in two long twintails.

A notable trait of her (much like almost every member of the Mafia), is that before, her eyes used to be entirely black. But after meeting Atsushi and being together with the Company, those blue eyes have been shown to become clearer.

She always dons a red Kimono with pattern of what looks like sprouts, and its yellow Datejime neatly tied. She wears long white socks and sandals; while on her arms, she appears to wear yellow and red wrist pads.

Kyouka carries with herself a tiny rabbit doll, together with his cellphone in a necklace.

Personality
While with the Port Mafia, Kyouka Izumi's personality is similar to that of a doll. She lacks all emotions and is ruthless when she is ordered to perform a duty. After being exposed to Atsushi and the real world, Izumi reverts back to a young teenager. She is easily infatuated with the small things and has a need to see everything.

Much like Atsushi, she believed that she was worth very little and that she deserved to die for her crimes. Although unlike Atsushi,  once she joins the Armed Detective Company  she does not dwell on her mistakes. She is strong willed and even states that she wants to prove to Akutagawa that she is more than just a killer.

Ability
Kyouka's ability, Demon Snow (夜叉白雪,), allows her to materialize a sword-wielding phantom, known as Demon Snow, which only follows orders coming from the mobile phone and does not comply to Kyouka's own wishes.

Background
It is mentioned on Chapter 18 by Kouyou that, before being an orphan, she supposedly lived happily with her parents. But ultimately, it was the Demon itself who killed them.

Since then, Kouyou took her, and served under the Mafia, as her protegee.

Plot
Kyouka first appeared at chapter 7, where she waited for someone. It was Dazai whom she awaited for, and using her Demon Snow, she kidnapped Dazai.
