Former chief at Yagiri Pharmaceuticals, currently secretary for Izaya.
Namie Yagiri (矢霧 波江, Yagiri Namie) is the Chief of Yagiri Pharmaceuticals and sister of Seiji Yagiri. She harbors somewhat incestuous feelings for her brother. She is behind the recent human hunting in Ikebukuro which involves kidnapping people whose disappearances would not be noticed for unknown experiments. She seems to rely on Shinra for some tasks, including keeping their secret. She doesn't like the fact that Seiji is in love with Celty's head. She wants to get rid of what she calls "that thing." After Yagiri Pharmaceuticals ends up merging with another company, she makes a deal with Izaya and becomes his secretary.
Namie is a young woman aged in her early to mid twenties. She has dark brown hair which she wears down that sweeps all the way to the small of her back and has a fringe swept to one side of her face. Her expression is usually stoic or angry, and she has pale skin and brown eyes. She wears a typical long white lab coat and a light green turtleneck shirt that changes to a darker shade of green at the bust and down. For her bottom garment she wears a dark red mini skirt and black leggings.
Namie Yagiri is portrayed throughout the show and manga as a very direct and strong woman - she works hard to get what she wants, and no matter what, she will get it. Her personality is seen as very demanding, only ever showing kindness and sweetness to her little brother (due to her having a complex for him). She outwardly displays her disdain for her boss Izaya, constantly insulting him and even appears to have a slight fear of him.
Dollars/ Mika Harima ArcEdit
Namie complains to her men that Seiji still hasn't been found. He escaped the men following him and can't be contacted by cell phone. Namie insists he cannot be found by the police. She thinks about the past, when she thought showing him 'it' would be harmless. She goes to Izaya's apartment where tells her quite a bit about herself, such as her name and that she is the chief of the 6th lab at Yagiri Pharmaceuticals, despite this being their first meeting. He hopes the list of illegal aliens he gave Namie was helpful, but she interrupts him demanding that he help her find Seiji.
She insists she is trying to help him, only to have Izaya say the stalker always thinks they're helping the stalker. Namie is furious at being compare to a stalker. He decides to help, but only in the way he sees fit. Upon seeing a mix of chess, shogi and othello pieces with a go board on Izaya's table, she asks what he's playing, but he ignores her and asks if she's jealous of the scarred girl. She denies this. In the past, Namie's uncle used to send her dolls, which she didn't like.
She wondered if he sent her the ones he liked without any regard for her, but she gave the dolls to Seiji anyway. The house was always big and often Seiji and Namie were the only ones in it. She often went into the study where she found a beautiful head in a jar and thought it was complete as just a head. Her uncle would talk to it, completely in love, but it was never more than a doll to Namie, who didn't think twice about letting Seiji into the study one day. To keep him from it, Namie relocated it to the Pharmaceuticals for research purposes and thought that would be the end. Then her security card was stolen and the head was gone.
A little while later, Seiji called his sister and thought he might have killed someone. Namie was overjoyed that Seiji needed help and called her. When she arrived at his apartment, Seiji was eating ramen on the floor with some girl's bloodied feet next to him. Namie saw the head on his desk and knew he must have taken it, but said she would take care of everything. The next day Mikado Ryugime calls her and tells her to meet on the street.
She meets Mikado and they talk. Mikado asks her about Seiji and Mika Harima. Namie gets angry and yells at Mikado that this isn't a TV show. Then she calls out her men to finish Mikado. Mikado then does the Dollars meeting. Namie flees from it when Celty jumps in and starts knocking out her men. The next day she gives Izaya the head and hears Izaya and his plans of what he is going to do in Ikebukuro and how he is going to Valhalla.
She starts assisting Izaya.
Yellow Turban ArcEdit
She goes to Izaya's place but when she reaches the door a gun was pointed at her back. Shingen Kisintani held the gun. Izaya comes in and talks to Shingen. Then the gun turns out to be a toy gun. Namie threatens to sue Shingen however she would get arrested if she did. A couple nights later Izaya comes back with a black eye and Namie was amused by it.
She and Izaya simply serve the purpose of introducing Mairu and Kururi . They also discuss the consequence of having a dangerous assassin like Igor running amok through town. Shortly after everyone in the chatroom announces that they were all having a hotpot party, Izaya asked Namie if she wanted to have a hotpot party of their own. She simply brushes him off, telling Izaya not use her to heal his wounded ego because he didn't have any real friends to have a party with. In the end, however, it seems Namie caved in to Izaya's prodding and ended up cooking for the both of them. She also contemplates the idea of poisoning the food, but decides against it. The color illustrations rate the cooking skills of some of the girls and Namie is ranked at a 95 just barely below Mika (100).
Through a flashback from Akane, the details on how Izaya manipulated her were revealed. When Izaya agreed to meet Akane as "Nakura" he had Namie appear at the meeting in his place. Namie then introduced an impostor as Izaya and her colleague and they proceeded to gain Akane's trust over the next several days. Namie, the imposter, and Akane would usually spend these days at Manga Cafe's or at family resturaunts (almost like actual parents) with Akane staying at Namie's place when she had to rest. Eventually, Izaya put his actual plan into motion and manipulated Akane into attacking Shizuo.
