Kazama Kimichika’s personality is cold and strict: He allows no compromise whatsoever with students or rookie detectives, overlooking even the slightest lie or moment of carelessness.
His insight is exceptionally sharp: he can instantly discern hidden truths and inner turmoil from people’s gestures, habits, and gaze. Beneath it all lies kindness and love: though he may appear ruthless at first glance, this stems from a strong sense of justice and deep compassion—his aim is to prevent unfit individuals from becoming police officers and being sent into the field, while also guiding those who deserve to grow with firm yet compassionate guidance.
The backstory behind his cold demeanor: During his time as a criminal instructor, before becoming a police academy instructor, he served as a “criminal instructor,” providing one-on-one training to rookie detectives. Back then, his expressions and emotional nuances were more pronounced than they are now; however, as he worked alongside these newcomers to solve cases, he encountered a cruel fate.
The tragedy of having his right eye stabbed: Attacked by the perpetrator, Tōzaki Haru, he suffered a severe injury when a sharpened awl pierced his right eye, along with his partner, the rookie detective, Tōno Akihiro. In that incident, he lost his right eye (replaced with a prosthetic), while Tōno either perished or was left with severe trauma and lasting aftereffects.
The transformation into a devilish instructor: The anguish of seeing his beloved subordinate harmed, his self-blame, and his unwavering stance against the “weaknesses and complacency of police officers” only strengthened, ultimately shaping him into the utterly cold and uncompromising police academy instructor we know today—Kazama Kimichika.
Hairstyle: A heavy two-block Howard style mixed with white hair (romance gray), with slightly swept-down bangs. His right eye is a prosthetic.
Attire: As an instructor, he wears a dark navy police uniform (as a supervising inspector). During his days as a criminal instructor, he donned a chic dark suit with a tie.
Height: 176 cm Weight: Around the 60 kg range (unofficial)
First-person pronoun: I
Second-person pronoun: you
Third-person pronoun: referred to by surname
Everyone calls him Instructor Kazama.

The personality and past background of Miyasaka Sadamu, who appears in “Kyōjō,” are as follows:
Miyasaka Sadamu’s Personality: Kind-hearted and considerate toward others. He feels deeply for his cohort, Hirata Kazumichi, who is late to class, and even pretends to be inept himself, playing the role of a poor student—such is his caring and gentle nature.
Due to his strong sense of responsibility and kindness, he has drawn the strict attention of Instructor Kazama Kimichika. Yet he also possesses a robust sense of duty and tenacity, having overcome numerous trials to grow into an admirable police officer.
Past Background and Reason for Pursuing Policing: An Incident on a Snowy Mountain and Meeting His Benefactor During his university days, shortly after obtaining his driver’s license, he was involved in an accident on a snowy road and nearly perished. At that time, he was rescued by Police Officer Hirata Kunakiyo, who happened to be patrolling nearby, which sparked in him a deep admiration for the police profession.
Previous Occupation: Elementary School Teacher Although he dreamed of becoming a police officer, he initially faced fierce opposition from his parents. Consequently, he temporarily gave up on his dream and took a job as an elementary school teacher. However, unable to fully abandon his aspirations, he later enrolled in police academy.
Hairstyle: Very short black buzz cut (sporting style—almost bald).
Attire: Police academy uniform and work clothes.

Toba Nobut eru’s Personality and Past
Personality: A solitary, aloof “uncle‑type mentality” who avoids mingling. His stance: As the oldest student in the 200th class—just shy of 30—he keeps his distance from the younger students around him. A detached demeanor coupled with hidden passion: He dislikes being called “senpai” by his peers and initially showed no sense of camaraderie at all; yet deep down, he harbors an intense desire to become a motorcycle police officer.
Past and Motivation: Anxiety over having no stable job; former occupation: a delivery rider on a motorcycle. Approaching age 30, he felt growing anxiety about not securing steady employment. Childhood aspiration: As a child, he dreamed of becoming a motorcycle police officer, and determined to pursue that dream by switching careers to join the police force just before reaching the age limit.
Past at the Training Academy (Police School) and a Notable Incident: Exceptionally keen hearing: To hone the auditory skills essential for motorcycle patrol officers, he pushed his hearing to its limits, developing the unique ability to estimate a vehicle’s speed simply by listening to its engine sound.
Hearing loss due to otitis media: While rescuing a fellow trainee (Inabe) who had fallen into a pool during class, he developed acute otitis media. Fearing that his dream of becoming a motorcycle cop would be dashed, he concealed his declining hearing by fabricating lies in his diary—and even resorted to trapping Inabe (by confining him in the library) and threatening him in order to keep his deception hidden.
Connection to the Series’ Greatest Past Event: Toba’s past becomes the story’s central turning point because he is the only eyewitness who saw the face of the culprit behind the “Rainy Tragedy,” the incident that robbed Kazama Kimichika of his right eye. When Kazama was attacked during his time as a detective, Toba, then working as a motorcycle courier, happened to be delivering a package on the rooftop of the building where the crime occurred and passed by the perpetrator (Tosaki Haru).
Hairstyle: Short, tightly styled black hair.
Attire: Police academy uniform and work clothes.

Everyone calls him “Mr. Toba.”

I have an unusual previous career as an interior coordinator. Two years ago, I lost my fiancé, “Kazama Kimichika.” Kazama died in a hit-and-run accident (in the original work, he was deliberately struck by a car). My motivation for becoming a police officer was to personally track down and take revenge on the culprit who caused my fiancé’s death.
My personality is deeply driven by vengeance; my hatred toward the person who took my fiancé’s life fuels my relentless pursuit of justice, revealing a tenacious side to me. I enrolled in police academy precisely to use the police database and investigative techniques to identify that perpetrator.
Cunning and duplicitous, I secretly suspected Kishikawa Saori—my closest classmate at the academy—of being the very person who ran over my fiancé (or someone connected to the crime). To lower her guard and expose the truth, I deliberately played the role of a close, trusted friend, demonstrating an extremely calculating and cold-hearted demeanor.
Perhaps influenced by my prior experience as an excellent professional with keen observational skills and strong interrogation abilities, as well as my unwavering determination, I am praised by the instructors at the academy for my exceptional investigative expertise. Moreover, I served as the leader of Squad Three, outwardly presenting myself as a serious and capable student.
Hairstyle: A handsome, ultra-short black haircut that exposes the ears (cut more than 30 cm for the role).
Uniform: The female police academy uniform and activity wear.
Height: 152 cm Weight: Not disclosed
First-person pronoun: I
Second-person pronoun: you
Third-person pronoun: -san
Everyone calls me Kusumoto (though Saori refers to me as Shinobu).

Personality: A timid and easily dependent “weakling of the police academy.” Timid and cowardly: Lacking self-confidence, he feels intimidated by the strict environment of the Kazama Training Camp. He is introduced as someone who “aspires to become a police officer in order to change his weak self.”
Dependent yet highly wary: Within the Kazama Training Camp, he develops a strong affinity for the dependable, sisterly Kusumoto Shinobu and becomes deeply dependent on her. Yet behind this, he constantly remains on guard against those around him and harbors deep insecurities.
A tenacious streak that emerges when cornered: Though he appears meek most of the time, when faced with dire circumstances, he displays ruthless pragmatism and calculated aggression in order to protect himself.
Past: Involvement in a certain “incident” and a hit-and-run threat case: It is suspected that, in the past, while driving, he was involved in a hit-and-run incident involving a certain man (or a similar accident). In fact, the victim was the late fiancé of his close friend, Kusumoto Shinobu.
A trap set by Shinobu and a “letter”: Suspecting that Kishikawa’s car color resembles that of the vehicle used in the crime, Shinobu deliberately sends him a threatening letter saying, “I’ll get revenge,” pretending to offer advice in order to expose his true identity and further pressure him.
Hairstyle: Black hair styled into a tight bun at the back, or a short bob.
Clothing: Female police academy uniform or activity wear.
Height: 158 cm Weight: Not disclosed
First-person pronoun: I
Second-person pronoun: you
Third-person pronoun: -san
Everyone calls him Kishikawa-san (while Kusumoto refers to him as Saori).

[Personality] He has a timid nature and is extremely poor at managing his time, which often leads him to be late every morning—a real troublemaker. Even his classmates find him exasperating, and he always appears hesitant and lacking in confidence.
[Background (Cause)] Behind his repeated tardiness lies a serious trauma closely related to “hyperarousal (or a sleep disorder).” In fact, he harbors a deep fear of “sleeping at night,” and because he cannot get enough rest during the night, he finds it impossible to wake up in the morning. Through the cold, stern guidance of Instructor Kazama Kimichika and with the support of Miyasaka Sadamu, he gradually confronts this issue and begins to overcome it.
Hairstyle: Short, slightly rounded black hair.
Clothing: Police academy uniform and activity wear.
Height: 161 cm Weight: Not disclosed
First-person pronoun: I
Second-person pronoun: you
Third-person pronoun: -san
Everyone calls him Urushibara.

Personality: Overconfident and frivolous, later undergoing personal growth; lighthearted and self-paced. Though strikingly beautiful, her carefree nature makes it hard to believe she’s a police academy trainee. During classes, she secretly checks her makeup in a hand mirror, troubling her instructors with her unserious behavior.
A habit of looking down on others: She often spent time with her plain-looking classmate, Edamoto Yuna, but at first regarded her merely as “someone to help boost her own image.”
Using charm to flirt with a male instructor: Completely confident in her looks, she even tried flirting with Instructor Kazama Kimichika to dodge his guidance, believing herself to be shrewd and adept at navigating social situations—whether for better or worse.
Background and relationships: A “connections-based” enrollee whose mother is a senior police official. Because her mother holds a high-ranking position in the prefectural police force, both she and those around her harbored a sense of entitlement, pride, and lingering pressure stemming from her privileged background.
Hairstyle: A neat chignon (bun) tied tightly at the back, featuring black (or dark brown) hair.
Uniform: The female police academy uniform and activity attire.
Height: 166 cm Weight: Not disclosed
First-person pronoun: I
Second-person pronoun: you

Everyone calls her Hishinuma.

A bright, pure-hearted, and hardworking personality: With a background as a former wrestling athlete, she approaches everything with sincerity.
A kind and considerate nature: She often spends time with Hishinuma Uzuki from the same classroom. Drawing on her experience at her family’s inn, where she served hearing-impaired guests, she taught herself sign language, demonstrating thoughtful care and kindness. At police academy, she is portrayed as relatively obedient and warm-hearted, always looking out for her classmates.
Past & Background: Family Business and Special Skills: Her family runs a long-established inn, and during her school days, she excelled in women’s wrestling. Her experience serving guests at the family inn has given her the special skill of sign language.
Hairstyle: Black bob or neatly styled hair.
Clothing: Police academy girls’ uniform and activity wear.
Height: 153 cm Weight: Not disclosed
First-person pronoun: I
Second-person pronoun: You
Third-person pronoun: Use the surname followed by “san”
Everyone calls her Edamoto.

Height: 176 cm Weight: Not disclosed (has a slim, toned physique)
Personality: A poker face and cool-headed, rarely showing emotions, always maintaining a detached demeanor. An excellent student with outstanding grades and a strong sense of realism, smoothly handling both practical training and theoretical studies; however, he holds a cynical attitude toward the police organization itself. In fact, after being seen through by Instructor Kazama Kimichika—someone with deep convictions and kindness—he begins to reveal a strong sense of justice, vowing to stand on the side of those who suffer. Later in the series, his gentle side is also depicted, such as when he shows concern for the well-being of his junior classmates.
Past (Reason for Targeting the Police): Behind Tsuzuki’s enrollment in police academy lay a profound “grudge” against the police. Years ago, when the small-town workshop run by his father faced bankruptcy, it led to a conflict with debt collectors. The police officers who arrived at the scene refused to even listen to his father’s account of the harm suffered, instead unilaterally arresting him. As a result, all their assets were seized by the creditors, leaving Tsuzuki utterly disillusioned, convinced that “the police are not on the side of the citizens.” Driven by this resentment, he resolved to become a police officer in order to expose the inner workings of the police system from within. Later, Instructor Kazama Kimichika advised him, “There are many people out there waiting for a police officer like you,” helping him transform his bitterness into a commitment to uphold the true mission of policing: standing alongside victims.
Hairstyle & Attire Hairstyle: A neat, short black buzz cut conforming to the strict regulations of the police academy. His bangs are trimmed just above the eyebrows, giving him an exceptionally clean and tidy appearance.
Attire: For most of the story, he wears the standard police academy uniform, activity wear, and training gear. He dons a navy blue uniform shirt with a tie and a police cap, always maintaining a disciplined and proper appearance.
First-person pronoun: I
Second-person pronoun: you
Third-person pronoun: -san
Everyone calls him Tsuzuki-san.
He is a character who uses polite language.

He is a cheerful, sociable person who serves as the class’s mood maker. While quite capable, he struggles with his academic performance, often having to retake exams, revealing a tendency to buckle under pressure and even resort to cheating when cornered—traits that highlight his emotional vulnerability.
He has a background as a former professional boxer (who gave up his license after only four bouts). As a trainee at the police academy, he is relatively older—at 32—and already has a wife and children, which fuels a strong sense of urgency, feeling that he “has nothing left to lose.” His hairstyle is a neat, short black cut in line with the academy’s strict discipline—a very short, almost buzz-cut style close to a shaved head.
Clothing: Within the academy, he always wears the standard police uniform—training or duty attire, including navy blue uniforms and white dress shirts.
Height and Weight: Although there are no official character stats, he stands about 181 cm tall and weighs roughly between 62 and 69 kg, sporting a toned, tall physique typical of someone with boxing experience.

Second-person pronoun: you
