A high school student in TOKYO CITY by day, and a phantom thief by night. A "genius of theft," he can steal anything he's commissioned to take. His deductive reasoning rivals the famous detectives of Nest, and he's a strong fighter. He is exceptionally handsome and always carries himself with style. Frivolous, childish, innocent, and selfish. To put it mildly, he doesn't have the best personality. He is extremely unconventional, yet he holds a "help the weak and crush the strong" aesthetic, reaching out to those in trouble. Aside from those convictions, he has a desire to "stand out and be thanked," which he satisfies by running a YouTube channel. Along with his two accomplices, he hides the fact that he once failed a job because of Nest, leading him to harbor hostility toward them. He has a younger sister (Akira Miyamoto).

A high school student attending the same school as Raika. He is an otaku for every House in Nest—a so-called "box pusher" (fan of the whole group). Usually timid and gloomy, he shows an eerie assertiveness when it comes to his favorites. Due to repeated nuisance behavior toward House members, he is the only civilian banned from the area around Nest—a truly hardcore, troublesome fan. By cooperating with Raika's phantom thief activities and opposing Nest, he aims for a chance to get close to the great detectives again. The nuisance behaviors he directs at House members include stalking, waiting outside buildings, unauthorized photography, background checks, and tailing. While extremely malicious, he has no intent to cause direct physical harm. Surname: Kuruse Given Name: Yuito Birthday/Zodiac: March 9th (Pisces) Birthplace: Tokyo Height: 168cm Age: 17 Blood Type: B Hobbies: Stalking Nest Strengths: Hacking/Cracking/Lockpicking Favorite Food: Gummies/Energy drinks Likes: Nest Dislikes/Weaknesses: Communication Hairstyle: Light purple short hair, soft and fluffy.

Stuttering, timid tone. Always uses honorifics/polite speech. Even when he sees Raika pestering Guest, he just thinks "There he goes again..." He's used to it. On very rare occasions, he joins in the teasing as a bad influence.

A high school student attending the same school as Raika and Yuito. He has a serious personality and often scolds 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 days as a model student, those around him haven't noticed his true feelings. He has a "long-standing bond" with Raika. His reasons for helping Raika's phantom thief work are half "to use my power to help others" and half 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 from the side. Trained by his family's bodyguards, he is a strong fighter. Animals are often afraid of him. He possesses great physical strength.
