Template:Arc InfoboxThe Daily Life Arc is the 1st story arc of the Katekyō Hitman Reborn! series. It focuses on Tsuna's life as his infant home tutor Reborn appears and as he begins to learn about the Mafia. This is also when he begins to gain more Guardians and friends. During this arc, the manga felt very much like a light hearted comedy story, and while there was some fighting it wasn't a big focus of the plot. It was after this arc that the manga took a big turn, becoming a more serious toned and intense battle manga. Tsuna himself also changed into a capable fighter at the end of this arc, when during it he was still a weak boy who needed his friends to protect him.
Useless Tsuna and Home Tutor Reborn

The next day, Tsuna and Reborn are walking to school and bumps into Tsuna's crush, Kyoko Sasagawa. Reborn notices Tsuna's affection for her and shoots him with a Dying Will Bullet that gives him the strength to tell Kyoko how he feels. However, he ends up making her run away and is forced into a match with the school's Kendo Club Captain, Mochida.
