Nec

Nec (ネク, Neku) is a professional hacker employed by Izaya. She is his assistant and head of information. Her real name is Hisae Inari (井鳴寿枝, Inari Hisae); though due to the alternate pronunciation of Hisae she has the nickname Inarizushi (a kind of sushi). She appears to dislike her real name, however, which is made clear when she threatens to kill Izaya for using it.

As a hacker, she specializes in handling the articles of the deceased. She hacks into the recently deceased’s e-mail, credit card, and cloud service data and uses them from where they had left off or with activities, almost as if they came back to life and resumed activities on the internet. Thus fellow hackers have given her the nicknames “Necromancer” and “Necrophilia," out of fear and admiration for her abilities. However, she did not like those nicknames because “being long is not cute,” so she shortened it to Nec.

Appearance
She has long hair and wears gothic-lolita style black and red clothes along with glasses and cross-chain piercings on both ears. Due to her choice of apparel she appears to be younger, making it difficult for other characters to accurately pinpoint an age for her.

Personality
Nec is cheerful, childish, and teasing most of the time but becomes aggressive (usually toward Izaya) when someone mentions her real name, often hitting him in the neck and claiming she will kill him for revealing it.

She is usually relaxed even when the people around her are in danger, indifferent, and is very proud of her abilities as a hacker.

Background
Nec became involved with Izaya after hearing of his apparent death. This news led her to try and hack into his accounts and data. However, she attempted to hack into a server connected with Tsukumoya. He destroyed her computer as well her self-esteem. After months of grieving over her first failure, Izaya Orihara arrived at her door, having heard what had transpired, and sought to hire her for her skills. She became one of the top hackers and information processors in Candiru, working directly under Izaya and Isozaka shortly after that.

Izaya Orihara
She has stated that they have a more business relationship and does not see him as someone of the opposite sex when asked what her relationship to him was. She often states she would kill him for telling others her real name, but otherwise she doesn't display much hostile towards him and can be rather teasing with Izaya, having no issue to point out his shortcomings and errors. Nec also has stated that she is grateful to him for giving her a place to belong and a job.
