- Kurou Daijūji (大十字 九郎 Daijūji Kurō )Template:Category handler/numbered
- Voiced by: Kentarō Itō (anime), Healthy Tarō (PC)
- A financially poor detective and a former magic student at the Miskatonic University, Kurou is one day hired by the Hadou Financial Group to retrieve a powerful grimoire. In his search, he encounters the grimoire Al Azif, who bestows her power for him to utilize, becoming a magius, in order to fight members of the secretive Black Lodge. Although not a natural warrior, his strong sense of justice and morality allows him to effectively wield Al Azif's power and pilot the Deus Machina, Demonbane. When accessing Al Azif's power, his abilities skyrocket to superhuman levels, alongside levitation, adhesive webbing, a magical scimitar and hanguns and the power to generate illusionary copies.
- Kurou's name is the Japanese romanization equivalent of the name Titus Crow, the main character in a set of horror fiction novels written by Brian Lumley.
- Al Azif (アル・アジフ Aru Ajifu )Template:Category handler/numbered
- Voiced by: Rie Kanda (anime), Saki Asamiya (PC)
- The original copy of the Necronomicon (ネクロノミコン Nekuronomikon )Template:Category handler/numbered, and likely the most powerful grimoire in existence, it takes the appearance of a young girl. Al Azif makes a pact with Kurou after being chased by the Black Lodge, allowing him access to her near limitless power. When Kurou becomes a magius, Al changes into a chibi version of herself; similarly, when he gains access to the Demonbane, Al serves as the Deus Machina's secondary pilot. Normally direct, bold and upbeat, Al is also impatient with those who are slow to act in danger, yet realizes whenever she and Kurou are outclassed by more powerful members of the Black Lodge. Unlike her previous masters, she confides to Kurou he is the first person to treat her like a person, rather than a weapon.
- The name "Al Azif" is Arabic in origin, meaning "that nocturnal sound (made by insects) supposed to be the howling of demons". According to the Lovecraftian mythos, Al Azif was the original name of the Necronomicon.
Hadou Financial Group

Her grandfather, Kouzou Hadou (覇道 鋼造 Hadō Kōzō )Template:Category handler/numbered, took care of her after her parents were assassinated by Black Lodge agents, and ordered the creation of the Demonbane to defend Arkham City. Though she maintains a public image as a responsible leader, she is especially concerned for the damage that occurs to her grandfather's legacy or to the city, due to the many battles between Kurou and the Black Lodge. To accompany the technical support and repairs for the Demonbane, Ruri employs her servants Makoto, Chiaki, and Sonia for the task.

- Voiced by: Hikaru Midorikawa (anime), Hikaru (PC)

- Voiced by: Takumi Yamazaki (anime), Prof. Shiryū (PC)
- A flamboyant, eccentric mad scientist in the Black Lodge, he works for the organization to advance his research in mechanics and weaponry. Occasionally seen with an electric guitar, he serves as a source of comic relief to the series, due to his propensity for getting into various accidents and defeats at the hands of the Hadou Financial Group. Unlike other members of the Black Lodge, Doctor West does not possess any magical abilities, thus resorts to a simple assortment of machine guns and rocket launchers. However, he does construct a few Destroyer Robots to combat the Demonbane, in their initial engagements.
- His name is perhaps derived from Herbert West, a character in the short story Herbert West–Reanimator by H.P. Lovecraft.

Special moves include "Atlantis Strike", a flying kick assisted by the shinguards and "Lemuria Impact", where a sphere of zero mass and infinite heat and pressure is created over the opponent. Due to the nature of its power source, it can function without draining energy from the pilot's life.

Little does she know, she enters into a dark world, involving herself with Demonbane and the powerful forces that control the city.
Kishin Houkou Demonbane TV Anime
Kishin Houkou Demonbane TV is an animated adaptation of Kishin Houkou Demonbane for the PS2, which began airing on May 18, 2006, and ended on August 17, 2006. The characters showcased in the TV series differ slightly from those in the PS2 Game. For example; Metatron has a few seconds of screentime in the first few episodes then never shows up again, Sandalphon is never seen, Ryuuga is seen only in the ending sequence, and Dagon's design was changed entirely.
Kuro Daijuuji is a poor detective living in Arkham City. One day, he is asked by Ruri Hado of Hado Financial Group, to search for a magic grimoire. As Kuro searches for the book, he unexpectedly runs into Al Azif, a pretty girl who turns out to be the grimoire Kuro is searching for. While being chased by the Black Lodge, Al forges a contract with Kuro, bestowing him with powerful magic. Soon afterwards, Al also activates Demonbane, a Deus Machina owned by the Hado Financial Group, to combat the mechanical menace from the Black Lodge. With this, the war between the Hado Financial Group and the Black Lodge begins....
Demonbane TV's ending is entirely original, made up for the TV series. It at first takes after Al's good ending, but instead of having her drift through space for aeons, it has the Elder Gods Kurou and Al-Azif (from Al's true ending) rescue her and bring her right back to Arkham.
The superior quality of the ending to most of the series is attributed to the fact that the animation staff enlisted the aid of the original work's staff for the final episode.Template:Category handler/numberedTemplate:Category handler/numbered

Connections to HP Lovecraft in the Anime
Miskatonic University is a fictional university in the fictional town of Arkham, Massachusetts created by HP Lovecraft, an author of horror from the early 20th century. The Necronomicon is also a creation of HP Lovecraft who used the book of forbidden and maddening knowledge in several of his short stories.  Other lovecraftian tomes that appear in the story include the Pnakotic Manuscripts, the Book of Eibon, De Vermis Mysteriis and many others.
Eps 1 "I AM PROVIDENCE" is named after a line in one of the letters HP Lovecraft had written during his life. In 1977 fans of Lovecraft had created a headstone to mark his burial place and on it they put the line from his letter "I AM PROVIDENCE."
Eps 3, "Reaninator" is likely supposed to be a play on Herbert West: Reanimator is a story written by Lovecraft (The episode title is indeed "REANINATOR"; there is no spelling error).
Eps 4, "The Invaders" is also the name of a Cthulhu Mythos story by Henry Kuttner.
Eps 5, "The Shadow Over Innsmouth" is also a story of the same name by HP Lovecraft. The fishlike Deep Ones in the episode also feature in the short story.
eps 9, "The Hunt" is also the name of a Cthulhu Mythos story by Henry Kuttner.
Eps 11 "The Return of the Sorcerer" would but a nod to Clark Ashton Smith's "The Return of the Sorcerer." Clark Ashton Smith was a correspondent of HP Lovecraft while he lived. In the story itself, the Necronomicon is quoted.
Eps 12, "Strange Eons" is a name taken from the book written by Robert Bloch of the same name. Bloch was a good friend of HP Lovecraft. Bloch is best known for the novel turned movie he wrote called "Psycho." It references a line from the Necronomicon mentioned in several of Lovecraft's stories, "That is not dead which can eternal lie / And with strange aeons even death may die."
Al Azif's name is derived from the Arabic name for the Necronomicon, "Kitab al-Azif."
Azrad's name was taken from the name of the author of the Necronomicon, Abdul Alhazred.
The Shining Trapezohedron is also the name of an ancient artifact in the HP Lovecraft story "The Haunter of the Dark".
The guns of the Demonbane, Cthuga and Ithaqua, are names of creatures that appear in other Lovecraftian horror stories.
Often, Al is seen either sitting or sleeping on a squishy, large, orange object, with a single eye, which occasionally speaks. It has been assumed by fans that this object is, in fact, a Shoggoth, another creature from Lovecraft's stories.
There are currently 5 novel adaptations, three of which retell stories covered in Zanmataisei/Kishinhoukou, and the other two feature new story contents.
