Raika Miyamoto A high school student in TOKYO CITY by day, and a phantom thief by night. A "genius of theft," he can steal anything he is commissioned to take. His deductive reasoning is on par with the master detectives of Nest, and he is a strong fighter. He is exceptionally handsome and always behaves smartly. Frivolous, childish, innocent, and selfish. To put it bluntly, he doesn't have a great personality. Furthermore, he is extremely unconventional, but he holds an aesthetic of "helping the weak and crushing the strong," reaching out to those in trouble. Aside from those beliefs, he also has a desire to "stand out and be thanked." Although he and his two accomplices keep it hidden, he once failed a job because of Nest, and thus harbors hostility toward them. He has one younger sister whom he cherishes deeply. Yuito calls him a "normie," and he seems to be popular with girls. His only known family member is his sister; the existence of his father, mother, or grandparents is completely unknown. While he is a phantom thief, he isn't indiscriminate; he mostly operates in a way that punishes evildoers. To ensure no harm comes to his sister, he keeps his identity as a phantom thief a secret from her. His sister's name is Akura Miyamoto.

Yuito Kuruse A high school student attending the same school as Raika. An otaku for every house belonging to Nest—a so-called "Nest stan." Usually timid and gloomy, he shows an abnormal level of assertiveness when it comes to his favorites. Having repeatedly harassed house members, he is the only civilian banned from the area around Nest, making him a truly hardcore, troublesome fan. By cooperating with Raika's phantom thief activities and opposing Nest, he is looking for a chance to get close to the master detectives again. His harassment of house members includes stalking, waiting outside for them, unauthorized photography, behavioral surveillance, and tailing; while extremely malicious, he has no intention of causing direct physical harm. A timid and gloomy, troublesome otaku. On the other hand, he has a sharp-tongued side toward those he trusts. As a fan of all the houses, he has memorized almost everything there is to know about Nest. He eats very little and loves gummies, often leaving some in a small zip-lock bag or having them for breakfast. He is an accomplice in Raika's phantom thief business, but he aims for a chance to approach the detectives by opposing Nest. He is skilled at hacking and usually serves as the technical support rather than the muscle during heists. He is timid and has low self-esteem, but he is secretly quite admired.

Keigo Yoroizuka A high school student attending the same school as Raika and Yuito. He has a serious personality and often admonishes Raika and Yuito. Born into a prestigious family, he developed a strong sense of rebellion against society due to his home environment and oppression from his father. Since he spends his time as a model student, those around him haven't noticed his true feelings. He has an "inseparable bond" with Raika. 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 the need to keep a constant eye on him. He was trained by his family's bodyguards and is a strong fighter. A high school student in TOKYO CITY like Raika and Yuito. He has been an acquaintance of Raika since they were toddlers, forming an inseparable bond. Due to his serious nature, he often plays the role of the one scolding the other two. He has short gray hair and black eyes, and wears black-rimmed glasses at school (which are actually non-prescription). Perhaps because of the glasses, he is often feared by children. His family is quite wealthy, but he harbors strong resentment toward society due to his upbringing and his father's pressure. Because he acts as a model student at school, no one around him suspects his double life. He is an accomplice in Raika's phantom thief activities. He has a very solid build and is often teased by Yuito with nicknames like "Gorilla." Despite his appearance, he likes sweet things.

Muzen Jinryuji J.M. He hates lies and secrets. A member of the organization "Reichenbach," the Waterfall of the End. He is supposed to be only two years apart from Sakaki, but he looks extremely young and has pale skin. He tries to pull Madoka into Reichenbach but fails. He is a childhood friend of Jin's father, Rei, as well as Mr. Sakaki and Hajime Tenmei. He reportedly used to play pranks on Sakaki often. However, he suddenly vanished from the three of them without a word of goodbye (he claims that if he had said goodbye, one or two of them would have died). The following year, Hajime suddenly announced he would become a detective, and the year after that, Nest was established. The details are unknown. During the bombing incident at Tokyo Basement Wonder Park, he acted alongside Swallowtail while pretending to be the murdered Sanga Munekatsu. Also, an oden shop owner described him as "someone not registered in this fleeting world." (This likely has some significance, but the details are unknown.) He makes jokes in poor taste.
