This is a list of characters in the manga series D.N.Angel by Yukiru Sugisaki and its anime adaptation.
Character Voice:
Daisuke Niwa (丹羽 大助 Niwa Daisuke?) is the series protagonist who, after turning 14 and confessing his love to, and being rejected by his crush Risa Harada, discovers that a boy called Dark lives within him. Afterwards he transforms into Dark whenever he experiences feelings of love or intimacy with the girl he loves, but Dark can choose not to come out if he so wants. Initially this is Risa Harada, but after she rejects him, Daisuke finds himself falling in love with her twin sister, Riku Harada, who does return his feelings after realizing how kind-hearted and gentle he was. Perceptive, athletic, and artistic, Daisuke is also skilled in dodging traps, picking locks, and other thieving-type activities, due to the daily life-threatening trials his family has him undergo when he gets up in the morning and returns from school in the afternoons.
Though he regularly argues with his alter-ego Dark, he expresses concern for him when he is in danger or in pain. He misses Dark when they are separated within the series through magic, and their dynamic is that of an older/younger brother.
Character Voice:
Dark Mousy (ダーク・マウジー Dāku Maujī?), 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", (translated as "Phantom Dark" in the ADV Films dub of the anime) 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.
