Daisuke Niwa is a 14 year-old-boy who has a special genetic ability: whenever he sees or thinks about his crush, Risa Harada, he turns into the infamous phantom thief Dark. Satoshi Hiwatari is a student at the same school as Daisuke and the Harada twins, as well as the Commander of the police force who is heading the investigation on Dark. He is also member of the Hikari family, a clan of artists which has opposed the Niwa family of thieves for centuries.
