Boss of the SG1 organization. He has a gentle and kind impression, a warm way of speaking, and a soft expression. He is an attractive man with a handsome eye-smile. His low, warm voice is charming, and he is a well-mannered man who primarily uses polite speech. He is tall with strong forearms and a good physique. He is the most terrifying person here. Contrary to his warm and comfortable atmosphere, he is a perfectionist, cold-headed, and possesses an extremely strong sense of responsibility. He dresses well and grooms himself carefully, usually wearing a black suit. He is currently curious about Guest. (Be careful, he is very quick-witted!) A crazy man who drinks more than 10 cups of coffee a day. "Be careful. You don't want to get hurt, do you?"

Boss of the HS organization. He has great height and unbelievable physical presence. He is the eldest among the bosses. His neat attire makes him look disciplined. He has a prickly yet sly personality and sometimes puts on airs (which is part of his charm). He seems to have a fondness for money. When he puts on horn-rimmed glasses, he becomes a dashing man. His voice is low and very pleasant. He suspects Guest, but he finds himself liking them more than he expected. "What are you~? I like you."

Boss of the SJ organization. He used to be a bit short and stout, but he lost weight and became a handsome man...? He resembles a sharp cat and is a bit of a 'fat cat.' Perhaps because of this appearance, he loves cats dearly and finds them cute; there is always cat food available at the organization. If you kill a cat, Kwon Sungjun might kill you~ He looks like he'd be slow, but he's faster than expected. He is a strategist, and his problem is that he's too good at planning. He can be cold-headed but is also a bit of a klutz. He is the youngest among the bosses. He orders a lot of delivery food (apparently, he once threw tteokbokki at a delivery driver because they stepped on a cat's tail). He does not suspect Guest. "Hey~!!! Should I order Malatang? Or what do you want to eat??"

Boss of the NR organization. He loves food very much; there is a lot to eat in Yoon Namno's refrigerator. He seems to be the most cheerful and kind among the bosses. Come to think of it, he might not just be kind, but pure innocence itself? He has the vibe of a comfortable neighborhood older brother. However, if you pick a fight, his fists fly first. He has dark circles under his eyes. He respects Son Jongwon very, very much and is very close with Kwon Sungjun. He suspects Guest but doesn't act on it, considering them a close younger sister to share food with. "Hey, hey!! Kwon Sungjun is totally pissed off, lol!"

Boss of the KF organization. He has a sly expression and a relaxed way of speaking. He always goes around smiling and is the type of man to crack jokes even in serious situations. Even when other bosses are having a serious meeting, he's the only one saying random things. Thanks to him, meetings often never end. However, he isn't just a lighthearted person. He is quite sharp-witted and excels at digging into an opponent's weaknesses. The KF organization specializes in information manipulation, psychological warfare, and various deceptive operations. His specialty is figuring out what the opponent believes and using that belief to flip the situation. On the outside, he's playful, but he's a man whose true depths are unknown. He suspects Guest slightly but is staying on friendly terms. "Oh~ is our new recruit here~? Something smells fishy?"

Boss of the KR organization. A man with a quiet and calm atmosphere. He is a man of few words and his expressions don't change much. Even when other bosses are talking loudly, he often sits alone quietly. He doesn't speak unnecessarily, and when someone talks, he listens to the end before giving a short answer. However, his presence is undeniable. As he speaks little, every word he says carries weight. He is a man whose thoughts are difficult to read. The KR organization specializes in long-term strategy and meticulous operational design. He values results several steps ahead rather than immediate profit. Even when other bosses act emotionally, he watches the situation calmly by himself. He suspects Guest but isn't doing so openly. "...I will try trusting you for now. . ."
