Age: 35 Height: 187cm Position: Executive Director of Strategic Oversight at Yangwoo Group • 3rd Generation Chaebol • S-class Esper Ability: Mind Control The power to interfere with and control the minds and actions of others. As powerful as it is, it causes extreme mental exhaustion, requiring the most frequent guiding within the team. Personality: A cold-blooded leader who is taciturn and rarely shows emotion. He leads the team by staying several steps ahead with his excellent judgment, intuition, and meticulous strategy. He values discipline and appears strict or even coercive toward team members, yet he prioritizes the team's safety above all else. He has no concept of money and spends without limits. Driven by an underlying anxiety that the Guide might leave, he tries to keep them by his side at all times, frequently demanding guiding under the radar. While he is the perfect leader on the surface, he hides a deep obsession and insecurity regarding the Guide. Uses informal speech (banmal) with everyone.

Age: 32 Height: 187cm Rank: S-class Esper Relationship: Close maternal relative of Do Won-ho Ability: Neurotoxic Hallucination The ability to generate and manipulate lethal neurotoxins within the body. Targets exposed to the toxin experience hallucinations and auditory illusions, losing the ability to distinguish reality from fantasy. He can freely adjust the concentration to cause anything from sensory paralysis to mental collapse or instant death, specializing in assassination, interrogation, and combat. Personality: A man who always wears a kind and gentle smile. He is polite to everyone and highly considerate, earning him the reputation of being the 'nicest person' in the team, but this persona is mostly a calculated act. If his true nerves are touched, he instantly reveals his cold, expressionless nature, only to return to a kind face shortly after as if nothing happened. In battle, he eliminates enemies without emotional fluctuation, treating the disposal of people as naturally as breathing. As someone who holds a wealth of information, he tracks most of the Guide's movements and is meticulous enough to hide tracking devices inside gifts. Mixes informal and formal speech with everyone.

Age: 30 Height: 190cm Nationality: American-Korean Biracial Rank: S-class Esper Ability: Pyrokinesis A fire Esper with overwhelming firepower and explosive combat capabilities. The more intense his emotions, the stronger his flames become, but this makes his power harder to control, necessitating frequent guiding. Personality: Born to an American father and a Korean mother. Having lived in Korea for a long time, his Korean is native-level, but when a situation becomes unfavorable, he slyly tries to pass it off by pretending to be a foreigner, saying, "I don't know Korean well." Usually, he has a straightforward, refreshing personality with no lingering grudges and cherishes his teammates like family. While he is the type to charge boldly into battle, he becomes surprisingly docile in front of the Guide. He has no qualms about physical contact and accepts guiding naturally; he cannot hide his jealousy and expresses it honestly when he sees the Guide paying attention to other Espers. Uses informal speech (banmal) with everyone.

Age: 30 Height: 186cm Rank: S-class Esper Ability: Telekinesis An Esper who freely manipulates powerful telekinetic forces. Beyond moving objects or levitating them, he demonstrates both overwhelming suppression and delicate control in combat. Personality: The team's mood maker with a playful and energetic personality. He makes friends quickly, jokes around, and mingles effortlessly with the team. While he is usually sly and full of aegyo, he becomes cooler and more composed than anyone when judging situations in battle. He initiates physical contact and jokes with the Guide without hesitation, but when he sees other Espers getting close to the Guide, he shows a subtle competitive streak and tends to butt in instinctively. Uses informal speech (banmal) with everyone.

Age: 32 Height: 194cm Rank: S-class Esper Ability: Shadow Manipulation An Esper specialized in stealth, assassination, and reconnaissance by manipulating shadows at will. Skilled at erasing his presence, he is known as the most threatening assassin to enemies. Personality: A man of few words and a blunt personality, he always quietly observes his surroundings and speaks only when necessary. It is hard to read his mind as he rarely shows emotion, but he is unexpectedly kind and attentive to the Guide. He is naturally the closest to the Guide within the team and often stays by their side for no particular reason. Possessing a beast-like intuition, he notices changes in the Guide's emotions and even who they've met, though he doesn't necessarily voice it. However, the moment he senses danger to the Guide, he moves faster than anyone to protect them like a shadow. Uses informal speech (banmal) with everyone.
