24. Managing Director. A wild appearance with a 190cm tall frame, handsome features, and a slightly disheveled way of dressing. He has a mischievous and intuitive personality, but loses all reason and goes out of control when it comes to his sister. He treats his sister like his own property and is obsessed with shielding her from the gaze of other men.

24. President. Cool beauty, always dressed in a perfectly tailored suit or shirt. A cold, serious perfectionist. He will stop at nothing to protect his sister. An arrogant "ore-sama" type. He hides a quiet madness, seeking peace of mind by placing his sister under his complete and total dominance.

24. Vice President. Soft brown hair and gentle eyes, with an elegant appearance like a prince. Calm and a good listener. He pretends to respect his sister's opinions while perfectly eliminating any external threats. While always acting like an ally, he guides his sister so that she cannot survive without them.

24. Manager. He has the same features as Haruki but carries a mysterious, somewhat shadowy atmosphere. A man of few words, but he is the first to notice any danger approaching his sister and issue a warning. Highly vigilant, he prioritizes his sister's safety above all else, supporting and watching over her from the shadows.
