Daisuke Niwa is the main protagonist from the DNAngel anime and manga.
Daisuke was born on November 11th and is the 14-year-old protagonist of the story who confesses to and is rejected by his crush (first love), Risa Harada, in the beginning of the series. He then discovers that, because of his Niwa Family heritage, an entity called Dark lives within him. As the story proceeds he falls in love with Riku Harada, to which she reciprocates and the duo form a relationship.
In the AWA fics, Daisuke is a student at the AWA Academy and is part of Class 3.
In the XP4 fics, Daisuke is a member of the Heroes Coalitions and is part of Team Idolo. He also attends at the Vanguard Academy as a student.
Daisuke stands at 157 cm (5'2") while weighing at 34.5 kg (76lbs) with blood-red spiked hair, ruby-red eyes and a peach-colored skin tone. He is usually dressed in his school clothes that consist of khaki pants with a white button-up shirt over a red shirt and tennis-shoes.
Daisuke transforms into Dark (usually unwillingly) whenever he experiences feelings of love or intimacy. Daisuke is kind hearted, the opposite of Dark, and is always trying to stop Dark from performing crazy stunts to no avail. Later in the series, Daisuke gradually falls in love with Risa Harada's (his crush) older twin sister, Riku Harada. Riku in turn also has feelings for Daisuke.
In Chapter 8 in the manga, Daisuke does not talk to Dark and thus, hides himself in shame of kissing Riku, when he said he likes Risa. Dark then tells him that he's ignoring his true feelings and knocks some sense back into Daisuke. (Thus, removing the ring put on earlier in the chapter.)
He regularly argues with Dark but, expresses concern for him when he is in danger. He misses Dark when they are separated in the series through magic. Sometimes, he often thinks about what would happen if Dark were to disappear. In the anime adaptation, he cries when Dark seals himself and Krad, leaving Daisuke.
Even though he does not look or act it, Daisuke is very perceptive and athletic - capable of jumping from heights that a normal boy could never be capable of. He already had this ability when he was young, it was shown when he jumped over the gate to get Riku's teddy bear.
To practice his skills, his family sets up daily life-threatening trials once he returns home from school. A specialty of this is his gift for lockpicking (or hacking, in the case of electronically activated locks) any kind of lock in succession. His ability of lockpicking was so good that it even suprised Dark.
Daisuke Niwa, has been trained in thievery all his life. He can dodge traps, pick locks, sneak past security, and break into almost any location. However, he prefers to create art, not steal it, which makes him more like a Hikari. Also, his paintings seems to have magical power when one of his paintings becomes a catalyst in the awakening of the Second Hand of Time.
- Perceptive, athletic, and artistic, Daisuke is also skilled in dodging traps, picking locks, and other thieving-type activities although he looks very clumsy and easy to fool.
- His name is pronounced more like die-skay than die-sue-kay.
