Vongola GP is a Spin-off of the Manga Series, Katekyō Hitman Reborn! Unlike the original series which is written by Akira Amano, the Spin off series is written by Takayama Toshinori. The Spin off takes place in a very different setting, where instead of the Mafia, Racers exist. Racers use go-karts, and during a race anything goes, including any type of interference to prevent your opponent from winning. Tsuna is the descendant of the person know as the greatest racer in history, Primo but is absolutely horrible in the sport himself and has lost 999 races in a row. Tsuna races for Team Vongola, and is known as the disgrace of Nammimori town.
