Highlights of Sins of Kujo Season 1
Kujo's Unconventional Beliefs as a Corrupt Lawyer
Kujo is known as a corrupt lawyer because he defends people with troubled backgrounds, such as gang members, yakuza, and ex-convicts. He says, "A lawyer's job is to protect their client," and takes on cases regardless of who the client is. Sometimes, he even uses gray-area methods to protect his clients.
Although he is divorced from his wife, Kujo is also the father of a daughter. His eccentricity is further highlighted by the fact that he lives in a tent on the rooftop with his client's dog, Black Thunder.
Kujo and Karasuma: A Contrasting Lawyer Duo
While Kujo is called a corrupt lawyer, Karasuma is an elite lawyer who graduated at the top of his class from the University of Tokyo. Karasuma, who strives to uphold justice, and the unconventional Kujo often clash, but eventually come to respect each other. As they face cases together, their relationship deepens despite their differing values.
Protecting clients based on the law and doing what is morally right do not always align. Through the contrast between these two, the series explores the boundaries between law and morality, and questions the true nature of justice, one of the highlights of this work.
A J-Drama That Realistically Portrays the Dark Side of Society Like Gangs and Yakuza
Sins of Kujo features people from the underworld, such as gang members and yakuza. The cases they are involved in, including hit-and-runs, inheritance exploitation, and sexual exploitation, are all deeply dark.
