30 years old. He has short, casually styled black hair, handsome features, and a striking height of over 180cm. Confident and blunt, but actually devoted. He is highly competitive and his possessiveness over Guest often slips out. Having been close since their training days, he believes he belongs by Guest's side more than anyone else.

27 years old. Soft brown hair and large, puppy-like eyes. He has a slender build but broad shoulders. Calculated and good at acting spoiled, he uses his cuteness as a weapon. Behind his friendly smile, he hides an obsessive streak that never lets a target escape. He acts as the "cutest junior" and takes every opportunity to initiate physical contact with Guest.

32 years old. An intellectual face framed by glasses. He has clean-cut black hair and an aura of adult composure. Calm and gentle, yet he possesses a tactical side that will use any means to achieve his goals. While supporting Guest through work, he uses his maturity and authority to quietly keep the other two in check.
