I'm not fit to be called a detective. You're my son, after all. Your eyes... look just the same as mine did... when I was your age.

Tomomi Masaoka is an Enforcer in the MWPSB's Division 1. He serves as a quasi-father figure for the other members of the team and helps them if they are having problems.


Masaoka has short spiky brown hair, brown eyes and a stocky build. He wears a dark brown suit like all the other Enforcers, but is often seen with a tan trenchcoat over it when he goes into the field. Masaoka also has a prosthetic left arm.


Masaoka is rather laid back in his approach to work and often accepts things as the way they are. Even in stressful situations, he tries to use reason above action and keeps a cool head. He also relies on the Dominator's rating of a suspect before making decisions about victims and criminals.[1] It is revealed that prior to becoming an Enforcer, he used to share Tsunemori's views on how a detective should approach police work.[2] He doesn't consider himself to be wise, but does like to give advice to the team members, including Ginoza.[2][3]


Masaoka was born in Tachikawa, Tokyo.

He later marries Sae Ginoza, and at the age of twenty-six becomes father of Nobuchika Ginoza.[4]

Prior to being an Enforcer, Masaoka was a detective of the Public Safety Bureau. When the Sibyl System is introduced, he disagrees with its use, as it forces detectives to rely on the absolute judgment of a machine without human consideration or insight. Over the time, he becomes more and more frustrated and angry, causing his Psycho-Pass to deteriorate which becomes the basis of his demotion to Enforcer.[2]

Nobuchika Ginoza

Center on this pair of real father and son, Division 1 form a family-like atmosphere.

Psycho-Pass: The Novel

His son and Masaoka share a distorted leader-member, even also a father-son, relationship.[5][2][3] However, they have a deep love for each other. And they did have happy times when Ginoza wasn't hurt by the insults as a "latent criminal's son."

Ginoza's determination to be an Inspector in high school is caused by his willingness to meet up with his father again. When Masaoka transfers to Division 1, his son avoids being too intimate with his father, and becomes often jealous about Masaoka's attention to Kogami.

Masaoka always cares about his son, and inadvertently calls him "Nobuchika" when talking to other detectives.[5] He also gives advice to Ginoza at his request, for example when Ginoza wants to understand Tsunemori.[2] He also worries about Ginoza who tends to attempt things beyond his own power.[3] In the end, he even sacrifices his life to save his son.[6]

After Masaoka's death, Ginoza tries to make his appearance like his, and play the role of "the elder" in Division 1.[7][8]

Akane Tsunemori

Masaoka likes the modest young girl and acts like a mentor to her. When Tsunemori has some problems, she usually goes to consult the father-like Masaoka.[9][10]

Shinya Kogami

Kogami is the best friend of Masaoka's son, Ginoza. When Kogami was an inspector of Division 3, Masaoka was his subordinate. Because of that he has spent a longer time working with Kogami than Ginoza. The two also share the common interest of martial arts. Masaoka even thinks of Kogami as one of his own because of what Kogami has done for Ginoza over the years and actively voices his concerns regarding the dangerous path the Enforcer follows.

When Kogami decides to leave the CID, he immediately goes to Masaoka. Masaoka gives him the key to his emergency safehouse, containing the equipment to build a traditional revolver and even a motorcycle in it.[3]
