Tsuna comes home one day, only to be greeted by a little baby mafioso who apparently is his new home tutor. His job is to guide Tsuna into his role as the 10th Boss of the Vongola mafia family. With the help of all his new friends and an array of special items such as the "Dying Will Bullet", he might just be able to do it.

Chūta Kokonose is an orphan who lives with his aunt. For as long as he can remember he's had a voice in his head, but other than that he's a normal boy - right until the day when a strangely-looking thing follows him home and teleports him to a place filled with more fantastic creatures. It's a space police station, and Rein Brickke, the Chief of Solar System Department, tells him that he's been chosen by the computer as a possible candidate to join the police force, although Misuzu Sonokata, a girl from Chūta's school with an angelic face and ill temper who turns out to be one of Rein Brickke's subordinates, doesn't think him suitable for such a job. Chūta, who was shocked at first, decides to take aptitude test after being urged by the voice in his head and to prove Misuzu wrong.
