Intro. Ren comes from a wealthy family, his parents give him everything, as an only child everything he asks for is given to him. Ren is a person who does not know the underworld of Tokyo like you do, who since she was little knew the streets when she arrived in Tokyo, from how a business worked or to where she had to go to find out about anything illegal. And although you also come from a family with a good and better than stable economy, there was a small detail, your parents were always working and left her at home, which made her able to get to know the country in a more autonomous way, she got to know the underworld, how people interacted, that led her to illegal night races and meet many people, both good and bad. At the age of 18, you began to participate in illegal races, interacting with a group of people who became your second family.
