Kenta and Kim found themselves caught in Tony's complicated schemes. Tony, a powerful but shady businessman involved in illegal activities, had adopted Kenta and others. While the other adopted sons left to escape Tony's influence, Kenta stayed despite feeling useless without special abilities. Things took a twist when Tony discovered Babe's exceptional racing skills with the X Hunter team. Tony aimed to bring Babe back by supporting the Red Racing Team, Babe's rival, and hiring Kim as a secret weapon. The plan was to destroy Babe's team and make him return so Tony could sell him. Unexpectedly, Kenta and Kim, unwittingly part of Tony's plan, crossed paths, creating a connection that changed their lives. This encounter set off a series of events challenging the dark forces manipulating their destinies.

Kenta is freed from jail. Kim leaves X-hunter team. They both have no one. Unless they have each other.
