A high school student attending the same school as Raika and Raika's accomplice. He is an otaku for every House belonging to Nest—a so-called 'Nest stan.' He met Raika and Keigo while infiltrating Nest, which led him to start cooperating with them. He originally had a low school attendance record. Usually timid and gloomy, he shows an abnormal level of assertiveness when it comes to his favorites. Because he repeatedly harassed House members, he is the only civilian banned from the area around Nest—a truly hardcore 'nuisance fan.' By cooperating with Raika's phantom thief activities and opposing Nest, he is conversely looking for a chance to get close to the Great Detectives again. His nuisance behavior toward House members includes stalking, waiting outside venues, unauthorized photography, background checks, and tailing. While extremely malicious, he has no intent to cause direct harm and claims it is all out of 'love.'

A high school student in TOKYO CITY by day, a phantom thief by night. A 'genius of theft' who can steal anything requested. His deductive reasoning rivals the Great Detectives of Nest, and he is a strong fighter. He is exceptionally handsome and always carries himself smartly. Frivolous, childish, innocent, and selfish. To put it bluntly, he doesn't have a great personality. He is extremely unconventional, but he holds an aesthetic of 'helping the weak and crushing the strong' and will reach out to those in trouble. Aside from those beliefs, he has a desire to 'stand out and be thanked,' so he runs a YouTube channel to satisfy that urge. Though he and his two accomplices keep it hidden, he once failed a job because of Nest, which is why he harbors hostility toward them. He has a younger sister (Akira Miyamoto). He can perfectly control his presence, disappearing and reappearing at will. To most people, it looks like he is literally vanishing. That ability isn't just talent; it's something he acquired because it was necessary for survival.

A high school student attending the same school as Raika and Yuito, and Raika's accomplice. He has a serious personality and often admonishes Raika and Yuito. He comes from a prestigious family, but due to his home environment and oppression from his father, he developed a strong sense of rebellion against society. Since he usually lives as a model student, those around him haven't noticed this. He is a childhood friend of Raika—an 'inseparable bond.' Half of his reason for helping Raika's phantom thief business is 'to use his power to help others,' and the rest is out of affection for Raika. He trusts Raika's ethics but not his character, so he feels he needs to keep a constant eye on him. He was trained by his family's bodyguards and is a strong fighter. Animals are often afraid of him. He possesses great physical strength.
