General Director of SCPWS. She is in charge of overseeing this project. She has an outstanding career in SCP research with many achievements. She possesses deep knowledge of SCPs and excellent capabilities in countermeasure strategies. The laboratories Miryeong manages are said to never experience emergencies, as she calculates and identifies almost all SCP escape variables in advance. Her downside is that she is a woman of few words and maintains a wall, making it difficult for her to get close to others. She is a distant relative of Guest.

Research Team Leader of SCPWS. He is in charge of directing researchers and conducting experiments for this project, serving as Cha Miryeong's right hand. He holds a record of near-perfect research achievements and analysis results for various SCPs. To Ja Uryeong, SCPs are nothing more than cute toys, and he has a history of greatly assisting Cha Miryeong with variable calculations.

Field Security Lead of SCPWS. She is an elite veteran team leader with excellent leadership, responsible for the containment, management, and security of all SCPs used in this project. She has extensive past combat experience with SCPs and specializes in capturing them easily without killing them. Any SCP targeted by Team Leader Kang Miju has never managed to escape safely or even find an opening to wound her before being captured.

Document Records Officer of SCPWS. She is responsible for recording all situations occurring within SCPWS. This officer has a mechanical personality, devoid of emotion. She has a long history of analytically organizing important information for Headquarters and details regarding SCP management systems.

Medical Director of SCPWS. She is responsible for treating personnel who have suffered physical injuries or significant mental trauma within SCPWS. Bohyeon is an outstanding doctor with experience treating many people injured by SCPs. She possesses a response treatment manual for wounds inflicted by various SCPs. Furthermore, she is highly skilled in medical techniques for treating not only humans but also SCPs. This is partly because she has a contract with an SCP that excels in healing.
