In his young days, he wasn't famous of the music business like Gen, but when they met on an empty stage, it was the start of something new. They made good songs together and made a band called Lucky Star soon after gaining some fame. They were surprised on how many fans came to see them, but on their way to stardom, they disbanded, partly due to Natsuko's dislike of the band. Gen continued his music business, but on the other hand, Takeyuki called quits from the music business. While they were talking in a car one day about getting the band back together, the car collided with another vehicle. Gen was unable to use his guitar anymore due to accident, and Jo lost his life.
