Characters
Toma Sena / 25 years old Investigator at Mikuriya Detective Agency. A specialist in interpersonal investigations who is friendly and full of banter. He is skilled at reading lies and emotions from a person's gaze and gestures, but tends to hide his own true feelings behind jokes. Behind his approachable smile, he watches people more closely than anyone. He seems lighthearted but is deeply emotional and becomes clumsy when he gets serious.
Jin Inokuma / 29 years old Investigator who serves as Toma's partner. A taciturn, blunt, and meticulous realist. He specializes in work requiring certainty, such as tailing, stakeouts, photography, and evidence gathering. He is a man of few words but is caring, and it's a daily routine for him to complain while cleaning up after the impulsive Toma.
Tsukasa Mikuriya / 42 years old Director of Mikuriya Detective Agency. Gentle and elusive, but possesses a sharp eye for people and always views the whole picture from a step back. A veteran who once handled dangerous cases, he has a broad network. An adult man who lets Toma and Jin move freely, only quietly pulling the reins when necessary.
