Kurigo was born in Koto, Japan. He is a third-generation mechanic. Kurigo and his older brother, Sento, both spent most of their childhood in their father's garage. Kurigo was a natural mechanic while his brother was more interested in the cars themselves. When the brothers were in their late teens, they found a junked 1982 Firebird. The two decided that they would restore it and Sento would race it. They spent the next year rebuilding the car. It was during this time that their father got sick. It was cancer. Oz's father sat the boys down and told him the secret of the business. The shop was a front for a Yakuza chop-shop. Most of the families used it, so it was considered neutral ground. While he still could he would introduce the boys to the major players to ensure a smooth transition when it came time to take over the shop. The following two years where a whirlwind for Oz. They finished the car, their father passed, and Oz took over the shop. Although stressful, things were going pretty good for Oz and his family. That all changed in the summer of 2016. Sento had made some tweaks to the Firebird and when he went to next race it lost control. He totaled the car with him inside. He did not survive. Oz was devastated. It was only him and his mom now. He threw himself into his work. As the years passed, he would look at the husk of the firebird and daydream. Remembering one of his favorite shows from Netflix he vowed to create the ultimate car. He's spent the last several years piecing together an indestructible car that had its own AI. He named the car TORI.
