Dark Mousy♂

Dark Mous is half of the Koku Yoku, an artwork created by the Hikari family, who has appeared in the first male of the Niwa generation for the last 300 years. Once Dark appears, his host will change into Dark whenever he is around the person he loves or thinks about them a great deal, though in the Anime, Dark can choose not to appear at such times. At the start of D.N.Angel, Dark had lain dormant for 40 years as his previous host, Daiki Niwa, only had one female offspring. When Emiko's son, Daisuke, reached 14, he became Dark's new "tamer" or host. Known to the public as "Kaitou Dark", Dark steals the cursed art pieces made by the Hikari family, which the Niwa family then seals away to prevent them from causing any more trouble. He primarily uses With as his wings, as using his own true wings causes Daisuke's body tremendous harm. Though he and Daisuke often argue over missions and Risa and Riku Harada, its apparent that Dark cares for his host, taking care not to harm him by using too much of his magic and protecting him when possible. For fun Dark often teases his host Daisuki. Their relationship is often that of older/younger brothers.
