Kanna is the first detachment of Naraku. She appears to be a ten-year-old girl with white hair and clothing. As a "concealed incarnation" of Naraku, Kanna has no scent and no demonic aura, making her undetectable to InuYasha's senses and immune to demonic aura-related effects such as the Hakurei-zan barrier. Kanna is the only incarnation that Naraku trusts with important information about his actions, allowing her to give orders in his place. Kanna carries a demonic mirror that can steal the souls of those reflected in it. Once a soul is trapped by her mirror, Kanna can control that person's body to carry out her bidding; however, the mirror can be overwhelmed by an especially powerful soul such as Kagome's, forcing Kanna to release all of the trapped souls before the glass shatters. The mirror can also create a glass demon to copy the abilities of whatever it reflects, though Kanna herself suffers damage when the glass demon is wounded. In her last battle, Kanna is ordered by Naraku to commit suicide, shattering herself and her glass demon into thousands of tiny shards. Driven by Kanna's final thought, one of the shards hits Kagome's right eye and gives her the knowledge of how to destroy Naraku.
The Crimson Lord to whom Margery Daw is bound. He expresses his will through the divine vessel Grimoire, which takes the form of a book. He talks wildly, makes comments without remorse, and often teases Margery, often earning a retaliatory punch. He does genuinely care about her, however, perhaps not in the form of friendship but as a companion in battle.
The stereotypical mad scientist, Dantalion is not liked by most Denizens, even in the Bal Masque, because he would do research on their own people. Among the Trinity, Bel Peol doesn't like him and Sydonay hates him, but somehow Hecate seems close to him, even calling him "ojii-sama" (the greeting toward grandfathers or respectable seniors) and protects him most of the time from getting into trouble with the higher-ups. Often says "-domino" at the end of his sentences.
A gadget Dantalion created.
Khamsin is the Flame Haze contracted to Behemoth. While he is one of the oldest Flame Haze in history, perhaps even thousands of years old, he bears the appearance like a ten-year-old boy. Khamsin has the ability to create and move stone golem-like creatures and control stones. Khamsin comes to playing a major role in Shakugan no Shana III (Final) than in the seasons before. He helps Shana and Wilhelmina in order to stop the Snake of the Festival from creating Xanadu. In the end, Khamsin dies due to being hit in a battle right before the end of the fight. He says farewell to Wilhelmina, Margery Daw, Shana and Yoshida Kazumi, to whom he had plays a great role.
An elderly blacksmith and a friend of Inu-no-Taishou (InuYasha and Sesshoumaru's father) who forged the Tessaiga and the Tenseiga. He rarely appears unless to repair the damaged swords or instruct InuYasha in hidden powers within the Tessaiga. Toutousai can breathe fire and wields a giant forging hammer. He also is transported by a three eyed ox which can fly. ("Totosai" means "sword purification.")
One of Naraku's incarnations, he is a pale child who appears much later in the series. He was initially a part of Akago, or the infant, but was cut from him by a monk. Unlike Naraku, he will fight in hand to hand combat, as even Kagura mentions that he is not afraid to get his hands dirty. Like Naraku, he is also able to erect an extremely powerful barrier at will. His main task after being unleashed is to find a way to the border of the afterlife so that Naraku can obtain the final Shikon Jewel shard. For a while he rode the demon horse Entei, until Inuyasha defeated it. He often orders around Kagura and taunts her. Much later in the series, he created Moryomaru as protection for Akago.
