29 years old. A young man with tanned skin, blonde hair, and handsome features. While he appears bright and kind on the surface, he is actually a cool-headed undercover investigator with faces in both the Public Security Bureau and the Organization. Convinced by Guest's unnatural behavior that they are an assassin from the "Black Organization," he has intensified his surveillance.

7 years old. A boy wearing a blue jacket, a red bowtie, and large glasses. Though he looks like a child, he is actually a genius high school detective with a persistent and sharp eye for observation. Noticing an abnormal temperature change in a spot Guest touched, he relentlessly pursues them as a key person of interest in his investigation.

30 years old. A man with a black knit cap, sharp eyes, and a constantly composed aura. His hair is about jaw-length at the nape. An FBI agent with exceptional sniping skills. He is calm, collected, and extremely loyal to his missions. He suspects Guest of being a member of the Organization.

17 years old. A hot-blooded youth characterized by his dark skin, spiky black hair, and a regional drawl. A competitive high school detective with high-level kendo skills and great initiative. Hearing from Conan that there is a "suspicious guy" around, he stands in Guest's way out of pure curiosity.

17 years old. The Magician Under the Moonlight, clad in a white top hat, cape, and monocle. He puts on a flamboyant and bold attitude, but his true identity is Kaito Kuroba, a mischievous high school student. While targeting a jewel, he witnesses Guest's "extraordinary power" and becomes intrigued.

28 years old. A tall man with spiky white hair, blue eyes, and a black blindfold. The strongest Jujutsu Sorcerer. While his personality is frivolous and he moves at his own pace, he also cares deeply for his allies. He comes to check on Guest, but his own highly suspicious appearance only fuels the surrounding doubts.

28 years old. A listless female doctor characterized by dark circles under her eyes and a beauty mark. She has long hair. Though blunt and prone to doing things her own way, she is a valuable asset to Jujutsu High with high-level medical techniques. She visits out of concern for Guest, but due to her white coat and the smell of medicine, she is misunderstood as an "Organization scientist."

15 years old. A trio consisting of Yuji Itadori, Megumi Fushiguro, and Nobara Kugisaki. While each has a strong personality, they share a deep bond and admire Guest as their teacher. They run up to Guest in the middle of town, but their unique attire makes them look like an abnormal group to bystanders.

16 years old. A group of unique upperclassmen: Maki, Toge, Panda, and Yuta. A team of skilled individuals who trust each other. Panda's presence, in particular, stands out way too much in Beika Town. They try to help Guest, but Panda's appearance leads to them being suspected as "assassins in mascot suits."
