A friend of Walker Yumasaki and Erika Karisawa. He is a member of the gang Dollars.
Kadota and his friends admire his work
Kyohei Kadota is a relatively well-adjusted person compared to the rest of the cast. He says that the only reason he joined the Dollars was that one day he got a text message through his cell phone asking if he wanted to join. On an impulse, he decided to accept the text message, getting a link to a website and a password that opened up the "official" Dollars message board. He also likes that the only real rule of the gang is that if someone asks if you are a member of the Dollars, you have to say yes. Kadota is shown to have a job in construction as he works in interior design. He is usually seen hanging out with Walker Yumasaki, Saburo Togusa, and Erika Karisawa in their van.
It is also shown that Kadota and his friends were members of the Blue Squares until their leader Izumii was arrested for aggravated assault.
Kyohei Kadota was created by Ryohgo Narita for the light novel series Durarara!! His name refers to the light novelist Kadono Kohei. He made his first appearance in Volume 1, Chapter 1 in both the light novel and the manga. He appears in episode one of the anime. His anime counterpart was created by Takahiro Omori. He is voiced by Yuuichi Nakamura in the Japanese version and Steve Blum in the English version.
Kadota does not change too much over the course of the series. He is usually seen being more reserved than his friends and tends to be more level headed than others. People usually turn to Kadota for help with various problems and guidance since he is more mature than the friends he hangs out with. Despite being in multiple gangs, Kadota has a firm code of ethics and left the Blue Sqaures for the Dollars for that reason. He is also shown to do whatever it takes to help a friend in need no matter what the circumstance. Even though he is uptight and serious, he has a lighter side that Walker and Erika try to bring it out with their antics. The one thing people agree on is not to get on his bad side.

With Saburo's help, he remembers that Horada was Izumii's right hand man in the Blue Squares and is trying to take over the Scarves since the he recalls that defeated Squares were allowed to join the Scarves if they dropped their flags.
