In the city of Judoh, Claire Leonelli inherits the leadership of the Mafia group “Vampire” following the death of his father. To keep Claire’s and other criminal activities in check, the city’s Bureau of Urban Safety assigns Special Services Division operative Daisuke Aurora and a super android codenamed “J,” whose identity remains secret because androids are banned in the city. With both of them around, crime now has little room to breathe in Judoh.
