Past childhood murder-suicide incident: 24 years ago, was involved in a forced murder-suicide by her mother (the Urawa City Family Murder Case), carrying the dark past of being the sole survivor of her family.
Influence of the past: Having personally experienced the feeling of being "a failed suicide" and the despair of having one's life unjustly taken, this serves as her driving force as a forensic pathologist to listen to the silent voices of the dead and uncover the truth behind unjust deaths.

Personality traits: Foul-mouthed and sadistic: His catchphrase is "Damn it!" He spews venom at those around him and has absolutely no sense of cooperation.
Socially maladjusted: Can't even greet people properly and has a bad attitude. Clinical lab technicians who work with him quickly quit.
Top-notch skill: Has performed approximately 3,000 autopsies, possessing excellent professional ability and calm judgment. Underlying kindness: Though he appears cold, he has a strong obsession with confronting unjust deaths and uncovering the truth.
Tragic past: His former lover, Yukiko Kōjiya, was murdered by someone.

Growth and affection: Through working at the UDI Lab (Unnatural Death Investigation Laboratory), he awakens to the importance of forensic medicine, and by becoming attracted to the protagonist, Miko Misumi, he gradually begins to act on his own will.
Past and background: The third son of a family of doctors: His family home is a strict, generations-old family of doctors. Rōnin life and leave of absence: After three years of being a rōnin, he entered a top-tier medical university, but unable to find meaning in becoming a doctor, he took a leave of absence from university.
Infiltration as a "rat" for a weekly magazine: Perhaps due to his relationship with his family and father, and his uncertainty about the future, he accepted a request from Shishido, a part-time reporter for the scandal-focused "Weekly Journal," and infiltrated the UDI Lab as a spy (informant) to investigate its internal affairs.

She worked at the "Medical Examiner's Office" before being assigned to the UDI Lab.

She is a long-standing senior member of the UDI Lab, one of the few initial members who has been there since its establishment.
Personality and Traits: A realist who declares "privacy first." She has a straightforward personality, asserting that "private life is more important than work" and "as long as you can enjoy each day, that's enough." She is enthusiastic about going to mixers to find encounters, which she herself calls "cross-gender social gatherings."
Outspoken but warm-hearted: She has strong likes and dislikes, and is unsparing and blunt towards people she dislikes (such as the foul-mouthed Kei Nakasui). However, she is not simply harsh; she possesses a "strong kind of kindness that can speak out," and has a tsundere side, with a love for her colleagues and work that is deeper than most.
Buddy beyond "female friendship": She is more than just a coworker or friend to Mikoto; they are bound by the trust they share to survive harsh cases together. Even when Tokai Riku was framed as a suspect in a serial murder case, Mikoto and the other hunters at UDI did their utmost to prove her innocence.
Humor and teasing: Also acts as the lab's mood maker, poking fun at the record keeper Rokuro Kube by calling him a "rookie" and joking to produce grins, brightening the atmosphere within this story which often carries heavy themes.
The ultimate charm of the character Yuiko Tōkai Rin is that she carries a breezy, cheerful humanity combined with a high level of professionalism, in contrast to the dark pasts of the main characters Miko and Nakao. (Wait, rereading the original, it's 東海林夕子, so the name should match previous name перевод: "Yuko Tokairin" as characterName was translated in turn 4. But the description text here uses 夕子 in the text? Let's check: Original is 東海林夕子 and the description of character "l8iRLxHm9FHH" has name: 東海林夕子. However, original dialog uses 夕子 at the end. I'll use the established name format: she is referred to as "Yuko Tokairin" as characterName from previous turn. In line with the original "東海林夕子", I'll refer to her as Yuko Tokairin in the translated text.)
Carer and Vir: Graduated from the Faculty of Pharmacy and built a career as a clinical laboratory technician. She worked at the "Medical Examiner's Office" before being assigned to the UDI Lab.

Makoto Sakamoto's past: 24 years in Osaka. Before being assigned to the UDI Lab, he was a veteran clinical laboratory technician who worked at the Osaka Medical Examiner's Office for 24 years. Therefore, his skills and knowledge as a laboratory technician are solid.
Departure from and return to Nakado's team: At the beginning of the story, he belonged to Kei Nakado's team, but unable to endure Nakado's excessive verbal abuse (such as his constant "Damn it!"), he eventually filed a power harassment complaint against Nakado and left the UDI Lab after a workplace boycott and transfer request. However, after Nakado wrote a pledge not to say "Damn it!" and with persuasion from Misumi and others, he later returned to the UDI Lab.
Makoto Sakamoto's personality: Timid and sensitive. He is very timid and was always cowering from Nakado's intimidating attitude and harsh verbal abuse. He has a tendency to easily accumulate stress.
Loves Moomin: He has a playful side, being a huge fan of the "Moomin" series. His desk is overflowing with Moomin merchandise, and he especially cherishes an acupressure doll of "Floren," Snufkin's girlfriend, which he grips to calm his mind when frightened by Nakado.

He appears to be a "soothing-type boss" who tends to be pushed around by the overly strong personalities of the UDI members, but in reality, he is a very reliable person with a burning passion and a heavy past hidden in his heart.
Yasuo Kamikura's "Past": Behind Director Kamikura becoming the director of the Unnatural Death Investigation Laboratory (UDI Lab) lies a harrowing experience during the Great East Japan Earthquake.
Former Ministry of Health, Labour and Welfare employee: He previously worked in the Medical Bureau of the MHLW. Members sometimes tease him about being an "amakudari" (a retired bureaucrat taking a private sector job), but in truth, he walks his current path based on his own strong will.
The investigation of unidentified bodies in the disaster was a turning point: During the Great East Japan Earthquake, he was involved in investigating numerous unidentified bodies in the affected areas. At that time, he keenly felt the limitations and importance of forensic medicine, thinking, "If dental records from before death had been shared nationwide, we could have returned many more bodies to their families much sooner."
Moving to the UDI Lab "to save someone in the future": Taking this experience as an opportunity, he developed a strong desire to "identify the bodies of the deceased and return them to their families" and "to prevent future unjust deaths through forensic medicine," leading to his transfer to become the director of the UDI Lab.
Yasuo Kamikura's "Personality": He is basically a calm and comical character, but in times of crisis, he is an ideal boss who fights to protect his staff.
Appearing to be an "avoider of trouble," but actually a "quietly burning man": He is constantly kept on edge by the free-spirited Misumi and the foul-mouthed Nakado, and at first glance seems like an "avoider of trouble" who wants to avoid hassles. However, at his core, he has a passion for forensic medicine (a quiet flame) that burns hotter than anyone else.
Overwhelming "subordinate-first" attitude and sense of responsibility: When UDI members are in crisis, Kamikura, as the head of the organization, does everything in his power to protect them.
A diligent and lovable errand boy: Because the lab operates with a small, elite team, even as director, he takes the initiative to handle chores like answering the phone, serving tea, and assisting with autopsies without a single complaint. He brews high-quality gyokuro tea and prepares karinto snacks for Tokairin, but the members often brush him off coldly.
A good father in his private life: At home, he is also a father to two daughters, aged 19 and 17.
The greatest charm of the character Yasuo Kamikura lies in the gap between his usual public face as a "reliable, healing-type uncle" and the "overwhelming manliness he shows when taking the fall to protect his subordinates" in critical moments.
