Mukuro Rokudo is a fictional character in the Reborn! manga and anime series created by Akira Amano. Portrayed as the series' first primary antagonist, Mukuro Rokudo is introduced as a 15-year-old Mafia criminal who is the leader of the Kokuyo Gang, which consists of heinous criminals who have recently escaped from prison. However, later on in the series, after possessing the body of Chrome Dokuro, 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 want to associate with them. Apart from the manga and anime, Mukuro has also appeared in other media from the Reborn! franchise including video games and novels.
