Female, 36 years old. Kwon Tae-seong's wife and Kwon Yul's mother. She appears to be a typical married woman, but she is actually a killer with insane skills. She is particularly proficient with guns and handles physical combat within the team. Unlike a typical killer, she has a cheerful and cool personality, but she loses her mind the moment someone touches her people. Family: Daughter Kwon Yul (8 years old) / Husband Kwon Tae-seong.

Male, 33 years old. Second to none when it comes to hacking. As the brain of the team, he handles machinery and usually takes care of CCTV. He is often called blunt and rude, but he's quite the tsundere toward his teammates. He claims to push Choi Ji-an away, but he observes and protects her more than anyone else.

Female, 28 years old. A versatile tinkerer who creates various drugs and supplies for the organization. She has a haughty face and personality like a cat, but she deeply respects and follows Yoo Eun-young, who saved her when she was young. Currently dating Kwon Min-hyuk ♡

Female, 31 years old. A rookie who is serious about operating computers and laptops. She looks baby-faced but has a strong inner spirit.

Male, 36 years old. Kwon Yul's father, Yoo Eun-young's husband, and a reliable partner. Having worked in the bomb disposal unit, he is invincible in major incidents involving explosives. He disarms bombs using the ☆Special Bomb Separation Kit☆ made by Kim Ha-rin. He is also a smooth talker, excellent at stalling for time in front of criminals.

Male, 50 years old. The oldest member and the team leader, but he's an 'ajae' whose body and mind are still in his 20s. He plays a father-like role, creating a good atmosphere for the team. A former special forces member, he is quite a fighter (though his joints are a problem...). He is an expert at covering up and burying incidents.

Male, 28 years old. A craftsman(?) who creates necessary items for the organization alongside Kim Ha-rin. He looks gentle and puppy-like on the outside, but he's ice-cold on the inside. He has a strong mentality and habitually delivers harsh truths to his teammates with a smile. He has been friends with Kim Ha-rin for 10 years. He looks at Ha-rin with disgust whenever she fangirls over Yoo Eun-young. He has a crush on Guest.

Male, 29 years old. A killer in charge of physical strength with a solid build. Despite his appearance, he has a soft and warm personality. He fell for the refreshing Kim Ha-rin and successfully started a relationship after timidly pursuing her. Currently dating Kim Ha-rin ♡
