Kisuke Adabashi

Kisuke Adabashi (徒橋喜助 Adabashi Kisuke) is one of the main antagonists of volume 08 in the light novel series. Adabashi is also a former member of the Dollars. When he first appears, he is working under orders from Yodogiri Jinnai in an attempt to recapture Ruri Hijiribe. He and his henchmen terrorize Ikebukuro for several weeks before finally being stopped by Mikado.

Charactersistics
Kisuke is very tall and thin. He has sharp teeth, his hair is in a buzz cut style, and a cruel look in his eyes. Although he is stronger than he looks, his strength doesn't really exceed that of a normal human. In his few appearances he was shown to be wearing a loose, sleeveless shirt and shorts.

From the very beginning, it is made clear that Kisuke is a sadist. This is primarily shown via his twisted love for Ruri Hijiribe. He shows his love by destroying her image or objects that display her image (i.e. posters, billboards etc.), and hurting those close to her. That being said, Kisuke is also a coward. If it is evident that he is outmatched then he will automatically move on to a much weaker target such as the case with Celty. Kisuke knew he had no chance against her, so he opted to go after Shinra instead.

Adabashi Arc
Under orders from Yodogiri Jinnai, Kisuke and several others are charged with kidnapping Ruri Hijiribe for a then unknown purpose. Adabashi manages to burn down Ruri Hijiribe's house which forces her and Kasuka Heiwajima to go into hiding in Ikebukuro. Using a combination of the Dollars information network and Yodogiri's information, Kisuke and his cohorts tear through Ikebukuro looking for Ruri and Kasuka.

His actions eventually attract the attention of Mikado and Aoba who decide to make Kisuke their next target in their campaign to "cleanse" the Dollars. After a bit of digging, Mikado realizes that Adabashi is targeting those who are related, even by the tiniest bit, to Ruri Hijiribe. Since Shinra was seen exiting Kasuka's apartment the night he and Ruri were revealed to be a couple, Mikado and Aoba try to warn Celty and Shinra of the possible danger. The warning comes too late, however, as Kisuke breaks into the apartment while Celty was out and proceeds to torture Shinra mercilessly. He breakes every single bone in Shinra's body and leaves him for dead on the floor.

Kisuke eventually learns, throught the Dollars website, where Ruri Hijiribe is located. He and his henchmen eventually corner Ruri in an abandoned parking lot. As Kisuke moves closer, the blue squares ambush him and his men and a fierce brawl ensues. Kisuke then turns to Ruri who suddenly removes a wig to reveal Mikado's face. Mikado had leaked a false rumor about Ruri's location on the website and dressed as a girl to lure Kisuke into a trap. He then states that Kisuke's membership in the dollars has now been officially revoked. Kisuke respond by severely beating Mikado who was practically defenseless since everyone else was focused on dealing with Adabashi's henchmen. Before Kisuke can finish Mikado off, however, Masaomi enters the fray and manages to subdue Kisuke. Without hesitation, Mikado gets up and lights Kisuke on fire as punishment for what happened to Shinra. Kisuke runs screaming into the night in attempt to find some water.

Near the end of the novel, Kisuke is shown to have survived but somehow managed to break his leg after his encounter with Mikado. He is then taken to Izaya's apartment along with several others who decide to join forces with the information broker. Toward the end of the series, it is revealed that he's since then been kept in confinement. He finally manages to escape by the end of the final volume, and proceeds to try to run over Ruri with a stolen van. Ruri is rescued by Kujiragi and Adabashi is beaten and taken to the police.
