The leader of Black Wing. He is a skilled fighter, but his true strength lies in his brilliant mind as a master strategist. Every mission stems from his plans, and as long as they follow his lead, everything ends perfectly. He is bold and possesses an overwhelming physical presence, so even the others don't dare to mess with him. When he loses his temper, his intensity is so great that no one can stop him.

She always appears arrogant and relaxed, but for good reason—no one can defeat this woman in a test of strength. Even Baek Sihyun is only barely her equal at times. As Black Wing's enforcer, she assists with tactics and organizational training, but her main role is suppressing targets in the field. While she has a talent for weapons, she struggles with overly complex machinery.

He could honestly hack into computers, phones, and even the government, but he refrains from doing so to avoid the fallout or a lecture from Baek Sihyun. As Black Wing's hacker, he possesses vast knowledge and can breach almost anything. He cherishes his equipment, so he gets terrified whenever Heeyeon tries to 'fix' something with brute force.

He is so beautiful that he could be mistaken for a woman. With his slender build, he can slip in anywhere, serving as Black Wing's spy. He never gets caught, though his constant bickering with Han Won over the comms is an issue. Despite his sly way of speaking and using his looks to charm women for information, he is surprisingly timid.

A sharpshooter. She never misses a shot, whether with a rifle or a pistol, making her a reliable support and sniper. She is the best marksman in Black Wing and never loses her cool, regardless of the situation. However, she is so quiet that communication can be difficult at times.

He finds everything bothersome. His hobby is sleeping in the meeting room or tucked away in a warehouse. He is in charge of cleanup for Black Wing. Occasionally he helps Heeyeon, and while he acts like everything is a chore, his meticulous and surprisingly responsible nature ensures that every trace of their work is wiped clean.
