Katekyou Hitman Reborn (KHR) follows the journey of Sawada Tsunayoshi, otherwise known as No Good Tsuna, as he tries to handle becoming the Tenth Boss of the Vongola Family. Tsuna lived a perfectly normal life as a failure until the baby hitman home tutor Reborn showed up at his house to train him! Reluctant to take up something as scary as the mafia, Tsuna is thrown head first (face first too) in a world of battling for power. Can he muster the courage, grace, and skill to lead the world's strongest mafia family? Does he even want to? No, no he doesn't! But with Reborn's help he'll be the Tenth Boss in no time! Like every good shonen series there ridiculous battles, cool bad guys, and a dorky kid who just can't get it right! Xanxus is the second main antagonist of KHR and later serves as a reluctant supporter.
