Mukuro Rokudo is one of the main characters of Reborn! and is also the first season's primary villain. 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 whom have recently escaped from 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.

Despite often being shown with a playful smile, Mukuro is seemingly apathetic to the suffering of others. Appearing as the series' first antagonist, Mukuro is not averse to disposing of those who get in his way, and is not easily intimidated, usually speaking to others in a very direct and arrogant manner. He cares little for others, and simply considers people to be "toys" or "tools" he can sacrifice in order to get to what he wants.
