Ap﻿pearance
Dark looks like a seventeen year old with long, violet hair, including bangs that cover a small portion of the center of his face. His eye are either purple or red, depending on the illustration.

His clothing is designed by Emiko Niwa, who ensures each one is unique and practical. His shirts, trousers, shoes, and optional capes and gloves are always black, though they may have silver or white accents.

If Daisuke transforms into him unwillingly, or unexpectedly, he dons Daisuke's school uniform. He also has black feathered wings, normally provided by his friend and pet With.

In the anime
Dark is usually seen wearing a high-collared black sleeveless shirt, with ivory stripes lining the zipper and the sleeves. His eyes are always purple.

Personality
Dark is an extremely skilled and confident thief; he enjoys heists almost as much as he enjoys taunting the police officers and Hikari that hunt him.

He is playful and flirtatious, easily talking with girls wearing his own face or the face of his tamer, and making Daisuke as flustered and frustrated as possible for his own enjoyment. Flirting with women is fun for him and he is not embarrassed when tackled by them or kissing them.

Dark is often impatient and very expressive, speaking loudly and bluntly or showing his emotions on his face. When enraged, he will mercilessly attack artworks who kidnap humans who "belong to him". Artworks calling him "Kokuyoku" rather than "Dark" will also anger him. Though Dark teases Daisuke for needing to be rescued often, he is genuinely worried when his tamer is in danger and secretly impressed when Daisuke displays his own thieving skills. Due to the nature of the Niwa curse, as long as Daisuke does not retreat into his own mind, Dark knows and experiences the teen's thoughts, feelings, and sensations. However, Dark does not share his own feelings or memories so easily and thus hides parts of his true nature from his other half.

Dark is opportunistic enough to prey on his tamers' insecurities and offer to become one with them. He does not hesitate to attempt to seize full control of Daisuke's body when the boy is distressed after they both kiss Riku. However, he also knows how to comfort his tamer and return him to his senses.

As time passes, Dark sacrifices more of his chances for winning both his lover and Daisuke's body in order to protect them. He vehemently rejects living as an "infection" like Krad. Though Dark does not acknowledge it, other characters believe that Dark's heart is changing, becoming more open to both the possibilities of being loved by Risa and of living in coexistence with the Niwas. He sometimes becomes frustrated with Daisuke's inability to "make a move" with Riku and encourages his tamer to act more like a boyfriend even as he thwarts these very attempts.

Dark speaks informally with everyone, including his loves and "elders", and never uses honorifics except mockingly.

In the anime, Dark is more silent, rarely talking to Daisuke internally except to warn him of dangers or tease the boy. For example, he once leaves his partner a written note laying out the terms of a bet. Despite his seductive side, he can show coldness toward women (like suggesting to a mourning girl that she kills herself). He will also let Daisuke solve problems on his own without much guidance.

Later on, he becomes more interested in helping Daisuke understand his own feelings towards Riku while at the same time Dark realizes he had been using Risa as a replacement for his true lover, Rika Harada.

He never apologizes for any of his actions, but is still capable of showing compassion for others, such as: giving Adonis another day with his lover, giving Menou another day to wait for Daiki, cheering up Emiko on her birthday, pulling Satoshi out of the ocean after a battle with Krad, and worrying for Daiki when his back is injured.

Past
Dark was created centuries prior to the events in the manga by the artist Hikari. He was intended to be a large painting called The Black Wings, but Hikari's ritual for injecting life into the artwork was interrupted by the phantom thief Niwa, who used the alias "Dark" at the time. As a result, half of Black Wings attached itself to the Niwa genes in the form of Dark's curse.

He has been hunted by the descendants of Hikari, who inherited his separated other half and arch nemesis, Krad. Though he and Krad "call out" to each other as halves of the same artwork, Krad cannot transform through Hikari females; this does not prevent the females from hunting Dark.

Over the centuries, the main branch of the Niwa family cooperated with Dark to steal Hikari artworks. Dark consciously mitigated the effects of his unintentional curse to ensure neither he nor his hosts suffered unnecessarily: he continued to make it difficult for the Niwas to fulfill their love (and pass on their cursed genes), but he only transformed their bodies through powerful feelings of love, which greatly reduced the pain and physical strain. Ninety-nine years prior to the present setting, the Niwas acquired a demon rabbit named With, whom Dark uses as his wings rather than generating his own.

Daiki Niwa was his 18th tamer, and Dark considers him to be very skilled. Before his 40-year disappearance, Dark casually suggested that Daiki "become one" with him. However, their lover had chosen Daiki over Dark at the time, so Dark smiled sadly and was not heard within Daiki again.

When Emiko Niwa was a small child, she cried out to Dark to let her become a phantom thief. He heard her but could do nothing.

Daisuke's First Heists
On November 11th, the day that Daisuke Niwa turns 14 years old, Dark emerges. He does not take control of Daisuke's transformed body until the boy is nearly captured by Satoshi Hiwatari during a heist for the Saint Tears. He praises Daisuke for making it so far on his own and uses With as a distraction to escape with his first stolen artwork in 40 years.

In the anime
Forty years before the main events, with Daiki Niwa as his host, Dark starts sealing the dangerous Adonis of the Promise Garden statue. However, the statue is swept away by the ocean before the ritual’s completion. Dark also falls in love with Rika Harada but doesn’t continue the relationship as his fate lies elsewhere.

Relationships
Daisuke Niwa: Though he and Daisuke often argue over missions and Risa and Riku, it's 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.

Riku Harada: Dark falls in love with Riku Harada, who is his initial Sacred Maiden.

In the anime, Dark calls Riku boring and doesn't pay her attention. He however later concedes that she can be cute when she’s asleep.

Risa Harada: Dark is pursued by Risa, who fell for him when she first saw him on the news. While he does not seem to reciprocate her feelings, he is moved by how dedicated she is towards him and even kisses her. Realising how serious her feelings are, he asks her on a date to Azumano Joyland... where he clearly rejects her for her sake. However, during the date, Risa is kidnapped by Argentine, and Dark rescues her, angry his date was stolen from him. He later dances with her at the school's dance party, reaffirming that he only thinks of her.

In the anime, despite having no feelings for her, Dark tries to kiss Risa and is only stopped by Daisuke. He finally manages to bring her to a date and kiss her. He however later informs the girl that he has no feelings for her and she only reminds him of her late grandmother. He later seems happy for her that she stops pursuing him.

Clarice Ng:
He was her half-blood brother though she sometimes doesn't remember her childhood. He let her be until the time comes he confess the truth during the Vampire parallel world. Like the rest of the other charters Dark really adores Clarice a lot that he vows to take care of her for Milizabeth and Orin. When Dark told Clarice to let go of the regret that she put Zero into she start to leave the past behind and on to the next challenge. Another time when Clarice's memory tape got stolen she can't hardly remember Licht and Dark when he first kissed her and Kateria knock her out unconscious leaving Dark in shock so he escape from the Dark Planet. Clarice finally got her memory back and told Dark to stay with her and the team and joined the Saber-Sword team including Licht too and to corroborate with the Team Tag Force.

Licht Bach:
Despite that Licht always the pervert looking at girls underwear Dark gets super angry. While Licht first met Clarice Dark never allows him to look at her underwear.
