Jinnai Yodogiri

Yadogiri Jinnai was formerly the head of Yadogiri Shinning Coroporation which was the talent agency Ruri Hijiribe worked for. In reality, he is a very sly information broker and is even more skilled at manipulating others than Izaya Orihara is. He is wanted by both the Police as well as the Awakusu but evades capture everytime. He is responsible for many of the events that occur in the series past volume 4 and can be considered the main antagonist over all.

Characteristics
Not much is known about Yadogiri in terms of both personality and physical appearance. All that is known about him is that he is middle aged, presumabley in his 40s, and that he is extremely good at what he does. He also has plastic surgery regularly in order to keep his pursuers from finding him. The picture featured above may even be out of date due to the events that occur during Volume 08.

Background
Very little is known about his past or his early life but he is responsible for much more than the incident with Ruri Hijiribe. Before the series starts, Yadogiri is apparently the one who sold the Demon Blade Saika over to Shingen Kishitani and is also the one who convinced him to steal Celty's Head. His motivations for this are unknown.

Biography
Volume 04: Yadogiri is only mentioned in Volume 04 by several members of the Awakusu who are searching for him. He abandons his facade as the head of his talent agency and goes into hiding.

Volume 05 & Volume 06: In another scheme of his, Yadogiri hires Russian Assassins Vorona and Slon to kidnap Akane Awakusu, the grandaughter of the head of the Awakusu for a, yet again, unknown purpose but his plans are thwarted when Akane unexpectedly comes into contact with Izaya. Izaya uses Akane to try to kill Shizuo Heiwajima which complicates the mission he entrusted to Vorona and Slon which resulted in failure.

On top of this, he also realizes that Izaya had sent Masaomi Kida and Saki Mikajima to dig up information about him. To keep from being found as well as to get back at Izaya for thwarting his plans. Yadogiri calls Izaya on his Cell phone and verbally taunts him for several minutes before stabbing him in the chest. He leaves Izaya bleeding on the sidewalk and runs off before anyone can notice him.

Volume 08: (NOTE: the information on Volume 08 is limited so there are many details that are left out) Yadogiri sends a man named Adabashi Kisuke to go after Ruri. His plans are thwarted this time by Mikado who lights adabashi on fire and sends him screaming into the night. It is revealed at the end of the novel that Yadogiri is working very closely with Seitarou Yagiri, the uncle of Namie and Seiji. Their main goals are:

1) to obtain Saika and it's current wielder, Sonohara Anri

2) to reclaim Ruri Hijiribe, the half Dulluhan

3) to reunite Celty and her head regardless of whether she wants to or not or what will happen to her afterwards.
