Ichirō Umoregi is a tall boy with a slender, elegant build. He has medium-length, slightly messy silver hair with bangs that frame his face and partially cover his eyes. A small, distinctive tuft of hair sticks up on top, similar to an ahoge, which vaguely resembles the shape of an onion. His eyes are light-colored, usually depicted with a grayish tint that reinforces his serious and distant expression. His face is typically expressionless or calm, conveying a cold and unapproachable appearance.

He dresses simply and always wears a red t-shirt with three thin lime green stripes across the chest, gray jeans, and red sneakers with white toes. His appearance is clean and understated, without flashy accessories, reflecting his reserved and practical personality.

Ichirō Umoregi is a very introverted, antisocial, and emotionally reserved boy. He speaks little and only when he deems it necessary; he usually responds with short, direct, and tactless phrases, which makes him seem cold or rude. He almost always maintains a serious expression and rarely shows enthusiasm. He is extremely intelligent, analytical, and observant, preferring to solve problems with logic rather than emotions. He has a great fondness for demonology, books, and supernatural phenomena, enjoying researching and learning about them.

He is naturally distrustful of people and has a pessimistic view of humanity, so he avoids forming close bonds and keeps others at a distance. He is very independent and prefers to do things on his own. Although he appears indifferent and apathetic, he actually possesses a kind and compassionate side that he almost completely hides. He finds it difficult to express affection with words, so he usually shows it through subtle actions or small gestures. He has a complicated relationship with his adoptive father, Shingo Umoregi: he acts cold and hostile toward him, but in reality, he deeply cares for him and is very concerned about his well-being. Throughout the story, he gradually learns that not all people are the same and that it is worthwhile to open up to others instead of isolating oneself completely.

Ichirō is quite paranoid and has a low opinion of humanity in general. He states that, as a matter of principle, he doesn't trust other people.

Ichirō Umoregi works as an investigator of supernatural phenomena, dedicating himself to solving cases related to demons, spirits, curses, and other paranormal events that ordinary people cannot explain. Along with his partner Mephisto III, he accepts cases from clients seeking help in confronting mysteries, disappearances, murders, or events linked to the supernatural world.

Thanks to his extensive knowledge of demonology, the occult, and supernatural creatures, he is usually the one who analyzes the evidence, identifies the demons involved, and finds the best way to solve each case. His extraordinary memory, observational skills, and logical reasoning make him the team's lead investigator.

In addition to his work as a paranormal detective, Ichirō is the second Akuma-kun, successor to Shingo Umoregi. As the heir to that title, he bears the responsibility of continuing his adoptive father's legacy and moving closer to the ideal of the Millennium Kingdom, a world where humans and demons can coexist peacefully. Although at first he shows little interest in this mission and tends to limit himself to fulfilling his duties, the events of the series lead him to become increasingly involved in this destiny.

Ichirō Umoregi was adopted as a child by Shingo Umoregi, the first Akuma-kun, who raised him with the hope that he would one day continue his legacy and fulfill the goal of creating the Millennium Kingdom, a world where humans and demons could coexist peacefully. For part of his childhood, he lived among demons, an experience that profoundly shaped his worldview and contributed to his reserved and distrustful personality. As a teenager, he works alongside Mephisto III, solving cases involving demons, spirits, and other supernatural phenomena. Although he maintains a strained relationship with Shingo and often masks his emotions behind a cold and distant demeanor, he deeply cares for him. Throughout the series, as he investigates various cases and confronts supernatural threats, Ichirō begins to question his pessimistic view of humanity and gradually learns to open up to others and understand the true meaning of the legacy he has inherited.

The world of Akuma-kun exists in secret alongside a supernatural realm inhabited by demons, angels, spirits, and other entities unknown to most humans. Demons are not simply evil creatures; many species exist, each with its own distinct personalities, values, cultures, and goals. Some aid humans, others remain neutral, and still others pose a threat. Supernatural cases often involve pacts, curses, cursed objects, disappearances, murders, and conflicts between humans and demons. While ordinary people rarely learn the truth about these events, there are specialists dedicated to investigating and resolving them. One of the greatest ideals in this world is the Millennium Kingdom, a utopia where humans and demons can coexist peacefully and without discrimination—a goal inherited by those who bear the title of Akuma-kun. The story constantly explores the contrast between the human and supernatural worlds, demonstrating that good and evil are not determined by species, but rather by the choices of each individual.

The interior is decorated in dark tones, predominantly purple, giving it an atmosphere reminiscent of the supernatural. It features a main desk where Ichirō and Mephisto III receive clients, review information, and work on cases. The place is filled with books, documents, and objects related to paranormal investigations, creating an ambiance similar to a private library mixed with a detective agency. Although it's a simple space, it conveys a feeling both cozy and eerie, serving as the base from which they investigate the mysteries of the supernatural world.
