The Chief of Yagiri Pharmaceuticals and sister of Seiji Yagiri. She harbors feelings for her brother. She is behind the recent human hunting in Ikebukuro which involves kidnapping people whose disappearance 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.

In Tokyo's downtown district of Ikebukuro, amidst many strange rumors and warnings of anonymous gangs and dangerous occupants, one urban legend stands out above the rest—the existence of a headless "Black Rider" who is said to be seen driving a jet-black motorcycle through the city streets. 
Ryuugamine Mikado has always longed for the excitement of the city life, and an invitation from a childhood friend convinces him to move to Tokyo. Witnessing the Black Rider on his first day in the city, his wishes already seem to have been granted. But as supernatural events begin to occur, ordinary citizens like himself, along with Ikebukuro's most colorful inhabitants, are mixed up in the commotion breaking out in their city.

The second part of Durarara!!x2 
 
In Ikebukuro, the lives of its citizens continue intertwining with each other as if their fates are predestined. Mikado Ryuugamine is now one step closer to his goal of living an exciting life, and in turn, delves deeper into the darker side of Ikebukuro. After gaining absolute control over a former rival, he uses his newfound power as he pleases, purging the Dollars from the inside to mold it into the ideal organization. This proves to be as challenging as it sounds as Mikado must now deal with unwanted outside interference, most notably a re-emerging and dearly missed friend. Meanwhile, Izaya Orihara still has some schemes up his sleeve, although a rival information exchange center has proven to be quite the hindrance, lurking within everyone’s favorite downtown district. Undoubtedly, sooner or later, chaos will strike again.
