The series tells the story of the main character Tsunayoshi Sawada - a very clumsy 7th grader who is often teased by his friends as the useless Tsuna. One day, his mother invited a tutor to help him with his studies and the story started to get interesting from there. This tutor is not an ordinary character but a famous assassin with the nickname Reborn. And it was thanks to Reborn that Tsuna knew he was the Tenth Vongola (Juudaime) - the heir to the Vongola mafia series in Italy. Although at first he refused to accept the truth, but later because he had to protect his friends and teammates, he didn't take on the responsibility and became a great leader.
