Biography
IZAYA'S BIGGEST RIVAL

Shizuo stated that he grew up within a perfectly normal family and suffered no significant traumas during his childhood. His superhuman strength first surfaced when he got mad at Kasuka for eating the last cup of pudding. He managed to pick up the fridge but the strain was too much for him and he ended up in the hospital. As the years passed, Shizuo's body, after years of abuse, managed to build up enough strength to withstand Shizuo's outbursts and effectively give him unlimited strength with no negative consequences to his well-being.

Once Shizuo entered middle school, he quickly became friends with Tom Tanaka after saving him from some bullies. Tom gave Shizuo a lot of helpful advice on how to keep others from starting trouble with him such as bleaching his hair blonde so that he would be easy to recognize and earn a reputation. It manages to work until Shizuo entered high school and encountered Izaya Orihara for the first time. Shizuo and Izaya hated each other almost instantly and have developed a fierce rivalry. Their battles would frequently cause thousands of dollars in collateral damage requiring the frequent intervention of the police, as well as fellow classmate Hajime Shishizaki who was one of the only ones capable of standing up to Shizuo's immense strength.

Around his second or third year of high school, Izaya became wanted for a crime and he framed Shizuo as being his accomplice. Shizuo, who was under 18 at that time, flung a vending machine at the cops who tried to arrest him. The policemen investigated more and Shizuo was cleared of all charges. However, this incident caused his hatred of Izaya to escalate.

After graduating, Shizuo drifted from job to job constantly getting fired from each one due to his temper or because of Izaya's plotting. He was also approached by a talent scout and instead nearly beat him to death for annoying him. Kasuka intervened and the talent scout approached him instead. After that, Kasuka visited him and gave Shizuo the bartender uniforms that he wears so frequently and asked him to settle down a bit. However, thanks to Izaya, he also got fired from that job. Eventually, Shizuo found a job working for Tom's debt collectors agency as a bodyguard. However, Shizuo usually went overboard when shaking down a client which would usually end with the company having to pay for any collateral damage
