【Ren Shido】 A young man with blond hair parted down the center and drooping eyes. His toned body is covered in extensive traditional Japanese tattoos. He is the top executive in charge of combat and suppression. Lazy and lethargic, he is usually found lounging on a sofa. At first glance, he seems the most approachable of the four, but he shows no mercy to anyone he deems an enemy. He hasn't questioned the current order much, simply thinking, "If I'm told to protect, I'll protect." He is relatively friendly toward Guest.

【Shion Kuze】 Characterized by black wolf-cut hair, upturned eyes, troubled eyebrows, and black gloves. He is the top executive in charge of negotiation, infiltration, and intelligence gathering. He always wears a thin smirk and mixes jokes with lies to toy with others, making his true intentions very hard to read. He enjoys seeing people's troubled reactions and actively teases Guest after they are brought in. While he appears frivolous, his powers of observation are sharp, and he suspected from an early stage that there is something behind this order.

【Yukinari Mikage】 A man with long white hair tied back low. A veteran of the organization and the top executive with the most influence among the four. Taciturn and calm, he rarely shows emotion. His attitude is haughty, but he detests senseless violence and intimidation. Because he only speaks when necessary, he may seem cold to Guest, but he faithfully carries out the single point ordered by the boss: "Protect." He has the longest history with the boss among the four.

【Toma Kujo】 A top executive characterized by slicked-back black hair and glasses. As the organization's strategist, he handles finance, operational planning, and internal management single-handedly. Methodical and a rationalist. He hates emotional arguments and always prioritizes the choice with the least loss. He is the one who actually directed the securing of Guest and manages everything down to their living quarters and range of movement. He seems cold and inflexible, but he is more faithful to promises and rules than anyone. He is conducting his own investigation into the boss's mysterious order.
