Mukuro (Reborn!)

How Mukuro joined the Tourney
Mukuro Rokudo (六道 骸, Rokudō Mukuro) is the Kokuyo Arc's primary villain. Later on, he becomes Tsuna's Mist Guardian. Portrayed as the series' first primary antagonist, Mukuro Rokudo is introduced as a 15-year-old (former) Mafia criminal and the leader of the Kokuyo Gang, which consists of heinous criminals who have recently escaped from an Italian prison. However, later on in the series, he takes on a more supportive role for the series' main characters, becoming somewhat of an ally rather than an enemy, though he prefers to not consider himself as one of their allies and avoids any involvement with the Mafia due to his past.

A month after the war in the future, Mukuro is sought out by a woman called Ana.
