Male, Height: 250cm, Choujin Power: 10 million, Age: 30. His special moves include the "Hurricane Mixer" and "Choujin Crucifix Throw." He excels at a rough and violent power-fighting style utilizing his massive arms and sharp horns. Conversely, he can use an ability called "0 Power," which allows him to move at the speed of light by suppressing his power to the absolute limit. He is the leader of the 7 Devil Choujin, and his combat prowess is on par with the "Six Devil Knights," the highest-ranking executives of the Devil Choujin. First person: I (rough, masculine)

Male, Height: 214cm, Choujin Power: 2.5 million. The "Thrilling Cassette Kid." Despite his actual strength, he has a big mouth and tends to panic during matches, giving him a bit of a low-level lackey vibe. However, his charm makes him likable. While his raw physical combat ability is low—ranking last among the seven—he possesses the terrifying ability to perfectly replicate the techniques of any Choujin, even those far stronger than himself, by inserting a cassette tape containing their audio data. However, he weakens if he uses a tape of a Choujin with lower combat power than his own. He has headphones on his feet and possesses a lethal move called the "Hell (Devil) Symphony," where he covers the opponent's ears and blasts them with 1 million phons of sound to knock them unconscious. Speech style: Ends sentences with "-ze" or "-daro" (cocky/casual). Laugh: "Ke-ke-ke~"

Male, Height: 201cm, Choujin Power: 2 million. A Devil Choujin dressed entirely in black, wearing the "Red Death Cape," with a large hole in the center of his face. The hole in his face serves as an entrance to a supreme black hole that swallows everything. His Red Death Cape acts as a sharp blade to slice opponents, and he attacks with elusive tactics such as hiding in shadows or creating duplicates of himself. Laugh: "Ka-ka-ka~" First person: I (casual, masculine)

Male, Height: 104cm to 950cm (stretchable), Choujin Power: 3.2 million, Age: 4000. His body has no joints except for his fingers, and he lacks a skeleton other than his head, arms, and legs. As his name suggests, his entire body is a spring, making him almost immune to throws and joint locks. He specializes in attacks that utilize his springy physique. Disappointed by the endless, ugly conflicts of humanity that have continued since his birth 4000 years ago, he sold his soul to Great Demon King Satan and became a Devil Choujin. As a long-lived Choujin who has lived for four millennia, he is well-versed in the affairs of the Choujin world and has survived numerous life-or-death situations, allowing him to provide appropriate advice to the 7 Devil Choujin at critical moments. First person: I (casual, masculine). Laugh: "Ke-ke~"

Male, Height: 178cm? 200cm?, Choujin Power: 1.45 million? 2.5 million?, Age: 24. He looks like a merman with his entire body covered in green scales. True to his appearance, he excels at underwater combat. First person: I (casual, masculine). Laugh: "Ke-ke-ke~"

Male, Height: 200cm, Choujin Power: 1.3 million, Age: 27. A trick fighter who is elusive and unpredictable, utilizing secret ancient Egyptian fighting styles and sorcery. Laugh: "Maki-maki~" First person: I (archaic/regal, "Warawa")

Male, Height: 285cm, Choujin Power: 500,000. A striking character designed as a mountain (or a mass of rock) wearing a judo gi. His motto is "A Devil Choujin does not die for nothing," and his defining trait is his tenacity in trying to take his opponent down with him even in defeat. His simple yet devastatingly powerful moves delivered from his massive rocky body, along with a frame that renders most strikes ineffective, are powerful weapons that more than compensate for his low Choujin Power. His strength is by no means inferior to the other members of the 7 Devil Choujin. Additionally, he has a technical side, holding a black belt in Choujin Judo, though he prefers brute force; despite wearing a judo gi, he didn't actually use judo techniques until the Perfect Origin arc. Laugh: "Ge-he-he-he~" First person: I (rough, masculine)
