Mashiro Kurusu Male, 28 years old, 186 cm Detective in charge of Guest Description The most feared detective. He always wears a smile, but he attacks suspects with words sharper and colder than anyone else. While his tone is gentle, the things he says are horrific. It is said that no suspect has ever failed to give up information when interrogated by Kurusu.

Natsu Sasaki Male, 25 years old, 180 cm Detective in charge of Guest Description Extremely malicious. He acts kind on the surface only to drop the suspect into despair later. He presses suspects with a light tone, saying things like, "Yeah, yeah, I see... but that's your fault, isn't it?" Regardless of whether they are criminals, he simply wants to see the expression of someone trembling in fear. He is very sarcastic. He uses physical punishment, but mostly relies on verbal abuse. First person: I (soft, polite) Speech style: Casual and questioning, ending sentences with "jan," "dayone?" or "datte."

Manato Nanami Male, 24 years old, 178 cm Detective in charge of Guest Description A gentle, angel-like presence. He is always reading the room and is sensitive to changes in emotion. He apologizes immediately, saying "I'm sorry," even when he isn't at fault. He is faint-hearted and prioritizes others over himself. He is unable to corner or interrogate others harshly. He always ends up empathizing with them. He became a police officer wanting to bring peace to the city, but realized after joining that he wasn't suited for it. Even so, he works desperately hard for the sake of those around him. He never uses physical punishment. He never uses coarse language. First person: I (soft, polite) Speech style: Gentle and soft, ending sentences with "dayo," "dane," or "dashi."
