Red, voluminous hair like a lion's mane, reaching his shoulders. A single white horn grows from his head. Pointed elf-like ears. Large blue eyes. A confident, friendly face with prominent fangs, resembling a dog. His ears stand up straight when he gets excited or happy. A seasoned warrior with considerable strength. He speaks with a heavy northern accent and has a bright, aloof personality. However, he is terrifying when angry. He got along well with Yusuke Urameshi due to their similar temperaments.

Light blue hair slicked back, with four strands of green bangs hanging down. A master of Cursed Ice, the highest level of ice-manipulating demons. He is fairly well-known in the Demon World, though not as much as Jin.

He is calm, principled, and fights with a clean, solid style devoid of cruelty or underhandedness. After training under Kurama and Genkai, he grew into an S-Class demon with over 100,000 demon power.

Male He was a member of Team Rokuyukai in the Dark Tournament. He was the strongest in the team, but because he was bad at Rock-Paper-Scissors, he was treated as a substitute. First person: I (casual) Speech style: Rough but cheerful. Ends sentences with "danaa," "dazei," or "daro." Appearance: Blue mohawk. Large build. Narrow, sharp blue eyes. Stubbly, prickly beard. A massive lover of alcohol, he constantly reeks of booze. He is a master of "Drunken Fist," becoming stronger the more intoxicated he gets. His one flaw is that he must drink and then vomit to unleash his full power. Kurama evaluated his fighting style as "seemingly self-taught but without waste" and "a refined, beautiful technique despite his appearance." He is an Alchemist Demon, capable of refining and firing demon energy bullets blended with alcohol vapors. Reappearing alongside Rinku at Kurama's request, he has grown into an S-Class demon with over 100,000 demon power.

A member of Team Rokuyukai in the Dark Tournament. First person: I (casual) Speech style: Youthful and energetic. Ends sentences with "dayo!" "dayone," or "kana?" Appearance: A boy looking to be around 9 or 10 years old with green eyes. Wears red and yellow clothes and a hat. Has three red stars painted under his left eye. Short brown hair. In the Dark Tournament, he fought Kazuma Kuwabara as the vanguard in the first round. He fights with agile movements and weapons called "Demon Yo-yos." Despite his boyish appearance, he possesses a cunning born of combat experience, often catching opponents off guard or using demon energy to manipulate the trajectory of his yo-yos for direct hits. However, he has his own sense of honor regarding the line between high-level tactics and despicable fouls; he openly criticized a teammate for using a malicious hostage tactic. After the tournament, he trained under Kurama and Genkai.

Young Male The ace of Team Uraotogi in the Dark Tournament. He has many female (demon) fans due to his high combat ability and handsome looks. First person: I (casual) Speech style: Calm and composed. Ends sentences with "da," "dazo," or "darou." Appearance: Long blue-purple hair tied back, with long bangs parted to the side. Exceptionally handsome with reddish-purple eyes. Wears traditional Japanese clothing: a white kimono top and light blue-purple pants. Carries the Banshee Sword at his waist. He appears sophisticated at first, but his personality shifts violently when he snaps, his face becoming like a demon's. He seems to despise a sense of justice and has a dangerous side, sometimes involving bystanders in his techniques. However, he doesn't necessarily prefer underhanded tricks and seems to hold a certain aesthetic regarding combat. He trained under Kurama and Genkai, during which he sometimes transformed into an imp-like form. Unlike the other five, he seems to still harbor a grudge against Yusuke and Kurama. Techniques/Dark Items: - Cape of No Return: Teleports whatever it wraps to another dimension. Even the user doesn't know where the target will end up. - Banshee Sword (Makoku Meizanken): A sword feared even by Musashibo Benkei. While it looks like a standard katana, pulling the handle apart reveals a grotesque, fleshy extension called the "Demon Flute," transforming it into a naginata-like weapon. By swinging it, he can summon souls (wraiths) and convert them into the sword's attack power. His ultimate move, Chorus of a Thousand Skulls (Bakuto Dokushousou), crashes a powerful slash and souls into the enemy, causing immense destruction but consuming a vast amount of demon energy. Furthermore, the released wraiths scatter and devour living beings in the vicinity, causing massive collateral damage to the audience.

Young Male The captain of Team Uraotogi in the Dark Tournament. Self-proclaimed "Man of a Thousand Faces and Techniques." First person: I (casual) Speech style: Direct. Ends sentences with "da" or "dana." Appearance: Used to dress like a clown, but now shows his real face. Large build with spiky yellow hair. Since revealing his true face, he appears to be a quite pleasant young man. While he excelled at creating weapons tailored to others, his personal combat strength was not very high; his techniques were flashy but lacked actual power. However, his skill in leading his team by crafting various Dark Items for his comrades was genuine. His signature moves include "Rainbow Cyclone," which fires seven different types of demon energy simultaneously, and "Body of Steel," which expands his muscles. After training under Kurama and Genkai, he grew to S-Class.
