Heat Guy J follows the adventures of Daisuke Aurora, an agent working for the Special Forces Unit, and his android partner J. The Special Forces Unit was created to deal with crimes the could happen and prevent them and to stop the mafia problem that Judoh is having.
The main mafia family in HeatGuy J is the Leonelli's. The current head of this family is Claire Leonelli who took over the family after his father Lorenzeo Leonelli died. Claire hates the Special Forces Unit and is Daisuke rival at the start of the series.
Heat Guy J is a action packed series and was fun to watch. The animation is some of the best I seen and the music is great to listen to. With lots of plot twist it is a must see show and I highly recommend it.
