The Golden Knight, and successor to the title and armour of GARO. Unlike his predecessor, he roams freely without jurisdiction over any region of Japan. His habit of dressing in black exudes a wild and imposing personality even though he is actually quite kind and positive. He possesses the ability to sense the feelings of others by touching their belongings.
Badass: As expected of a successor of GARO, his fighting skill is amazing.
Handicapped Badass: Loses his eyesight in episode 18. What does he do immediately afterwards? Train himself to compensate, then escapes from prison without the Garo armor.
Telepathy: Can determine people's feelings by touching their belonging as shown when he can feel the thought of the people in Vol City when touching a statue inside the city.
Aguri Kusugami (GAI)
Known as the "Sky Bow Knight", Aguri is the latest in a line of Makai Knights of the Kusugami clan. He approaches his responsibilities with a cold and analytical view bordering on heartless, but secretly worries that he cannot live up to the prestige his name carries.
Expy: Uses bow and arrow, wears glasses, stoic personality, look down on the main protagonist for his lack of skill, highly intelligent, and comes from a noble family in his profession. He's pretty much Uryu Ishida.
Insufferable Genius: He's kinda of a jerk, but without his planning they would never never have defeated the Horror in episode 3, Ryuga himself admitted this.
Jerkass: He doesn't show any concern about his teammates and didn't even tell them about his plan to fight a Horror despite using his teammates as pawns so the plan can work.
Jerk with a Heart of Gold: Turns out he's not so bad after all. He's the one who shed the most tears after knowing what the Madou Horror does to their victims souls. And as #19 shows, he will go through hell and back for his fellow comrades.
Stoic Spectacles: Aguri is the first Makai Knight to wear glasses. He's also pretty much like Kouga in term of temperament.
The Stoic: Hardly shows any emotion throughout his appearance so far.
Not So Stoic: As #13 shows, Aguri is not without emotion or sympathy. He even cries after finding out what the Madou Horrors does to the victims. And again in #20, at Ryuuga's reunion with his mother.
Takeru Jakuzure (ZEN)
Known as the "Flame Sword Knight", Takeru is a self-styled playboy who would rather find a lady friend than battle Horrors. He is the most extroverted of the three Makai Knights, but also the one least in control of his emotions.
Badass: Takeru may be a lecherous womanizer, but don't underestimate his ability in battle.
A Makai Priest based in Vol City. He acts as the commander of the Makai Knights cell within Vol City, and fights alongside an Makai Beast named Rago. He has a history with Ryuga, being the one who trained him in the past.
Big Good: Pretty much this in the Volt City conflict. Sonshi seems reluctant to take him on, and when you consider Sonshi's talent...
Worf Had The Flu: Despite the aforementioned reluctance, Sonshi was able to beat him when they fought offscreen. He said that he was too weakened from sending Lago after Tousei and Sonshi.
A beautiful and flashy Makai Priestess who is Priest Burai's only disciple. Intelligent and seductive, she supports the Makai Knights both behind the scenes, and in battle using a pistol armed with magical bullets.
Hair Decs: Looks like a woolly diamond-shaped ornament. It belonged to her father.
Hooker with a Heart of Gold: "Hooker" would be too much and thus downplayed but she dates rich men to obtain diamonds for her Madou tools. She was really concerned with a man she was dating after he was tempted by a Horror.
Ironic Echo: She told Enhou and Ryuga that she wants to bear their children. She is kidnapped by Tousei to make her give birth to madou plants.
Last Name Basis: Strangely, she calls Aguri by his family name, despite calling Ryuga by his first name in the previous episode.
The female commander of SG-1, the private security group in charge of imposing order within Vol City. Although she constantly clashes with Ryuga, she has a virtuous heart and wishes to gain enough power to protect the innocent within the city. She is turned into a Magic Horror by Tousei against her will, becoming a puppet under his control.
Action Girl: The commander of SG-1 and a skillful combatant.
Go Out with a Smile: How Ryuga and Rian knew that everything she did as a Madou Horror was not done willingly.
A news reporter known as the "Goddess of Justice". She delivers the daily "News Time" reports in Vol City and is absolutely trusted by the public. She is actually a Magic Horror and a high-ranking member of the conspiracy.
Weirdness Censor: Her "news" reports usually consist of "nothing bad happened today". This is because she is part of the conspiracy covering up the Horrors.
The mysterious head of the prestigious Kaneshiro Group that controls Vol City. He is actually a Puppet King controlled by Tousei Kaneshiro, who secretly seized control of Vol City through his Magic Horrors and used Kensui as a figurehead to deflect suspicion from himself.
A mysterious man who acts as the secretary to Kensui Kaneshiro, and seems to be linked to the Magic Horror conspiracy. He is a Magic Horror himself, and serves Tousei as his right-hand man. However before all those happened, he was also a former Makai Knight.
Badass Grandpa: A meta example too, being played by veteran martial arts actor, Yasuaki Kurata. Just to put this in perspective, he takes on Aguri, Takeru and Ryuga all at once and he barely seems to be having any problem.
One-Man Army: When you can take on three Makai Knights at once you earn the title.
Sai Guy: His other weapon other than his sword. Possibly an Actor Allusion due to the actor being known for using them in his movies.
Shadow Archetype: Not only is his full Horror form very Garo-like, its weapon is a sword, the most often seen Makai Knight weapon before Aguri came along.. Turns out, it's because he was formerly a Makai Knight.
An estranged son of Kensui Kaneshiro who owns and operates a steakhouse in Vol City. After encountering a Horror in his shop, he approaches Ryuga and attempts to provide him with assistance in his battle against the Horrors. He is actually the one behind the Magic Horror conspiracy, having created the Magic Horrors to seize control of Vol City from the shadows. After his true significance is revealed, he steps out of the shadows and becomes the public ruler of Vol City by assassinating the rest of the Kaneshiro Group.
Abusive Parents: Abandoned by his father for being a bastard. While turning her mother into an Inga Horror justifies calling him a monster, she also neglected him.
Bastard Bastard: He's Kensui Kaneshiro's son from a different mother, and thus the black sheep of his family. Apparently, his mother was raped by Kensui.
The Corrupter: He turned Enhou into a Madou Horror, and plans to turn Ryuuga into a Madou Horror as well. And before that, the first Madou Horror he made was his mother. All the Madou Horrors in Vol City were made by him.
Karmic Death He rubbed his status as a human in the faces of the Makai Knights, knowing quite well that they are forbidden to kill a single human. He then got turned into an Inga Horror, making him fair game.
Manipulative Bastard: He's very good at manipulating people, and even the Makai Knights have been dancing to his tune for most of the series - they just didn't know it.
Non-Action Big Bad: As expected from a regular human being, he's physically weak as shown as he was knocked unconscious when Takeru smacked him with his remaining hand. This is the guy that played the knights and priests for fools as far as 15 years back when it all started.
Psychopathic Manchild: His Evil Gloating can be likened to a child taunting a playmate, even with gleeful pointing and laughing, and he even threw a tantrum when he failed to stab Ryuga with a madou plant.
