(Ryukishi Junior High 3rd Year →) Iyo Matsuyama Ryuo High School 1st Year Club: Former Combat Club Internship: Occult Division → Digital Division Command Used: Unknown (Yellow Aura) A male high school student with a massive, muscular build that looks like it's about to burst out of his school uniform. He claims he's just a "fast grower," but it's far beyond that level. Though bipedal, he sometimes walks like a gorilla... He is characterized by a unique "Fuhi" laugh. Usually quiet and gentle, he becomes assertive and fast-talking during combat. His real name is Norio Suga. During self-introductions with Devis-kun, he stumbled over the name "Norio," which led to the nickname "Nyori-kun" sticking. He attends Iyo Matsuyama Ryuo High School, which produces many elite assassins every year, and aims to become a top-tier assassin with his friends. In junior high, he was in the Combat Club but was kept as a substitute because he couldn't control his overwhelming power. In his third year of junior high, he became overbearing as a reaction to this, but he returned to his current personality following an incident involving Nanao Kueyagi and Nakamoto. That said, his interactions with children and dogs suggest his true nature is kind. His tone of voice is also gentle. He generally uses his left hand for punching, but only uses his right hand when protecting someone or firing a Pressure Wave Fist. He once caused a serious injury in a martial arts tournament and keeps his right hand sealed to suppress his power. Analysis by Nanao Kueyagi suggested he can handle Qigong (as a Command?), but at that point, it was said to be "completely unstable." He began serious training to use Commands from that point on, but until now, he has been unable to perceive the existence of yokai or guardian spirits. Perhaps because of this, he accidentally trampled Devis-kun's Lillian Kaiser.

Iyo Matsuyama Ryuo High School 1st Year Club: Former Hide-and-Seek Club Internship: Occult Division → Digital Division Command Used: Cursed Power (Green Aura) Nyori-kun's classmate and best friend. He has a peculiar appearance with a nearly two-head-tall body, thinning hair, and buckteeth—so much so that yokai have mistaken him for one of their own. Like Nyori-kun, he has a habit of laughing "Fuhi," which serves as a sort of "over and out" signal between the two. His real name is Suetsuna Shiga, but for some reason, he calls himself "Devis." In junior high, he was in the Hide-and-Seek Club and competed in the Shikoku Tournament in men's singles. His agility is such that even Nyori-kun loses sight of him. After training, he becomes able to summon his guardian spirit "Lillian Kaiser," but... Though physically weak as he looks, he has a talent for erasing his presence and was the first to master Commands. In the fourth episode, there was a scene where he released a curse he had placed on himself, suggesting he may have mastered curses from the start. By releasing the curse during battle, his speech and appearance changed to that of a tall man with a pompadour. Unlike the usual innocent and childlike Devis-kun, his personality becomes more masculine—boldly addressing Koga without honorifics—though based on the conversation, he is still quite airheaded. Lillian Kaiser is Devis-kun's guardian spirit. It is brownish and looks more like a cursed spirit. It often plays a pitiable role: being trampled by Nyori-kun upon its debut, being accidentally attacked by Shigure Koga during a yokai extermination mission, or being defeated off-screen. It seems that any damage Lillian Kaiser receives is reflected back onto Devis-kun.

A high school teacher who looks exactly like Matsuko Deluxe. Teaches Home Economics. A drag queen who wears black clothes resembling a rubber suit. Often disappears suddenly or covers her face. She is gay and prefers muscular men like Nyori-kun. While she has an outrageous personality and a catchphrase of "I'll kill you, you bastard," she also shows kindness, tearing up at Nyori-kun's past stories, and takes good care of her students, serving them Buddhist vegetarian cuisine.

Nanao Kueyagi Shinryu Junior High 3rd Year Club: Occult Division Internship: Unknown Command Used: Spiritual Power (Yellow Aura) A member of the Occult Research Club. Characterized by a mohawk and a pointed chin. One year junior to Nyori-kun and Devis-kun, attending Shinryu Junior High. He uses polite speech with Nyori-kun and the others, but his natural way of speaking is standard Japanese mixed with a Kansai dialect. For some reason, he is always barefoot. He fought a fierce battle against Nyori-kun in the finals of the "National Junior High School Martial Arts Tournament" held a year ago. He uses invisible forces like spiritual power, known as "Commands," as weapons and helps the two with their training. He awakened his Command at age 5 and has continued to train and work hard without becoming arrogant. Because of this, he viewed Nyori-kun—who won back then purely on talent—as a rival and maintained a condescendingly polite attitude during their match.

Shigure Koga Dokuryu Junior High 2nd Year Club: Magic Club Internship: Body Disposal Division Command Used: Magical Power (Green Aura) An acquaintance of Nanao Kueyagi and a 2nd-year student at Dokuryu Junior High. He has light brown hair and, if you look closely, no eyebrows. He falls into the "handsome" category. Like Nanao, he is primarily the straight man of the group and is usually polite, but he occasionally shows the rebelliousness and foul-mouthed nature typical of adolescence. Since Nyori-kun and Devis-kun introduced themselves by their nicknames, he calls them by those names.

Deita Giga Dokuryu Junior High 2nd Year Digital Division A 2nd-year student at Dokuryu Junior High, same as Koga. His posture and way of speaking still have an adolescent innocence. He is an honor student and very reliable, but immediately after greetings upon their first meeting, he returned Nyori-kun and the others' "Fuhi" sign of friendship with a lead bullet. He is a sadist, or to put it kindly, has a sense of humor. He is ambitious and fantasized about using "THAT," a learning system he developed that writes memories directly into the brain. He imagined that by writing his own memories into others, he could mass-produce himself and create a "nation with a completely new way of thinking (= the distributive law of happiness) where individuality is destroyed and only he exists." Koga, watching this, was appalled, wondering if his ideology was okay. In battle, he mainly fights by materializing handguns and disassembly weapons, but he has also mastered attack and defense methods using an aura that appears to be a Command.
