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.
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.
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.
Calm and composed, he often pays little mind to those around him and rarely shows his emotions causing others to find him distant and cold.
Satoshi is shown to have a strong dislike for his adopted father, and refuses to play along when the man tries to pass the two of them off as a close family.
In the manga version, Satoshi and Daisuke are inconvenient but genuine friends who both try to protect each other from their alter egos, and their friendship is tested and strengthened by their mutual afflictions.
Whereas Daisuke is spared the pain of enduring the magic used by Dark via With, and Dark trying to keep the magic use to a minimum, Krad often uses the max amount of power he can summon, and when he takes over his white wings rip from Satoshi's back causing him great pain, and leaving two narrow injures on his back where the wings once were.
Character Voice: Krad (クラッド, Kuraddo) is an entity similar to Dark, living inside his "tamer" Satoshi Hiwatari.
He is Dark's opposite in many ways, including his name ('Dark' spelled backwards), having blond hair, wearing white attire, and always speaking very politely using an extremely formal speech pattern.
After seeing Daisuke's alter ego Dark, she falls in love with the thief and believes that he is the mysterious person she is destined to be with.
Innocent, spoiled, and depicted as "girly-girl", Risa is often seen as the opposite of her twin sister Riku, though both show the same stubbornness and tenacity, particularly when it comes to people they care about.
Satoshi Hiwatari is also seen as showing a bit of concern for her in the manga, deliberately transforming into Krad—something he normally fights—to try and save her when he sees her falling from a tower during Argentine's attack.
[1] As the series progresses, Risa's attitude and childish behavior dies down a bit, though she retains her girly nature.
Not wanting to tarnish those feelings or end up as a replacement, Risa gradually stopped pursuing Dark as a romantic interest.
While trying to sort out her feelings, she remembers that they had met as children when he'd helped her retrieve her precious teddy bear from over a fence one night.
Riku intensely dislikes Dark, feeling he is nothing but a thief and a playboy, however when Risa is in danger and he promises he will bring her back, she begins to soften her stance towards him.
When he married Emiko, he agreed to take on the Niwa last name, to retain the family surname for future generations.
At the start of the series, he has been on a journey for approximately 12 years, researching the phenomenon of Dark and the history of the Hikari and Niwa rivalry.
When Daisuke is pulled into his painting by the Second Hand of Time, Kosuke is able to explain the true history of the fairy tale, Ice and Snow and assist in rescuing his son.
After her death from illness, her spirit continued waiting for Daiki, mistaking Daisuke for his grandfather due to their strong visual resemblance.
Released from servitude by Satoshi and after she is helped by Daisuke, Towa chose to begin living in the Niwa household.
He sent Satoshi back to middle school to spy on Daisuke Niwa and also hired the young prodigy to become Chief Commander of Police and in charge of capturing Dark even though he always interferes.
In the anime, he was the one who found the voodoo doll that is Mio Hio and sent her to the same school as Satoshi to make Daisuke wear a magical pendant in exchange of giving her a real human body.
Argentine (アージェンタイン, Ājentain) is a mysterious boy who seems to have something against Dark, and kidnapped Risa during her date with the phantom thief.
During the twelfth book, he reveals that he is trying to recreate "Qualia," another piece of living artwork originally made to always be by his side.
In the December 2008 chapter he returns to be found in Daisuke's basement and is recruited by Emiko to be the family butler, much to Towa's displeasure.
During the Toki no Byoushin arc, he temporarily transferred to Daisuke's school in order to oversee the Ice and Snow play.
In order to obtain a real life, Kei tells her that she must sacrifice someone, Daisuke, by getting him to wear half of a pair of a powerful charm that would steal his soul.
[5] Bodiless, Mio's spirit later uses the Harada twins as a medium in order to both aid Daisuke and Dark, and to save Hiwatari's father when he tries to activate a living artwork.
In the anime, he falls in love with the character Mio Hio, a living voodoo doll, who did not return his affections.
