Characters appearing/mentioned in the story

Misaki Uchida(内田 美咲) - Psychiatrist whose specialty is in criminal psychology. She worked with the Tokumeigakari pair in a previous episode to track down a serial killer, Naotarō Anzai(安斉 直太郎), who also happened to be her assistant at the time,

After that incident, she started treating a parent of one of the victims, Asao Suetsugu(末次 朝雄). She voluntarily submitted information about Mr. Suetsugu's treatment sessions to the doctor deciding whether Mr. Suetsugu should stand trial. She also guesses that doctors probably decided to release Naotarō Anzai(安斉 直太郎) back to the society because Anzai was a model patient who never caused problems during his involuntarily hospitalization and also because no one can honestly predict whether someone will commit a crime. She also had been told that Anzai was scheduled to take practice walks outside the hospital.

Naotarō Anzai(安斉 直太郎) - The serial killer from a previous episode with victims in Fukuoka, Kyoto, and Tokyo/Saitama. He was Dr. Uchida's former assistant and a graduate student at a medical university, but was locked away in a psychiatric ward after his arrest. While there, he went through psychiatric evaluation and was determined mentally unfit to stand trial. As a result, the prosecutor decided not to press charges. After outrage from the surviving family members and the public, the prosecutor decided to have Anzai hospitalized for another evaluation, and as a result, Anzai was involuntarily hospitalized. Recently, a newspaper somehow discovered that Anzai was considered for release back into the public. Anzai is killed at the start of the episode while he was taking a walk outside as a part of the training to go back into society.

Maho Horikiri(堀切 真帆) - The nurse who was with Naotarō Anzai(安斉 直太郎) when he was killed. She accompanied Anzai on these walks because she was scheduled to health visit Anzai after he was released from the hospital. She claims that she was pushed from behind and didn't see the attacker's face.

Her family home is in Kyoto, and while she was still working there, she health visited Yurie Maki(牧 百合江).

Asao Suetsugu(末次 朝雄) - Father of the victim from Fukuoka. After Naotarō Anzai(安斉 直太郎) is killed, he walks into the Tokyo Metropolitan Police Department building and claims that he killed Anzai. Once inside the interrogation room, he acts as if he were completely insane. Dr. Misaki Uchida(内田 美咲) had been treating him after Anzai's arrest. During those sessions, he asked the doctor if she could tell him everything she knew about Naotarō Anzai(安斉 直太郎).

Yurie Maki(牧 百合江) - Mother of the victim from Kyoto. After hearing that Naotarō Anzai(安斉 直太郎) won't be tried in the court of law, she tried to commit suicide as a sign of protest but was discovered soon afterwards and survived.

Shigeo Murai(村木重雄) - Original serial murderer who appears in a flashback scene.

Osamu Hidaka(日高 修) - Father of the victim from Tokyo. After hearing that Naotarō Anzai(安斉 直太郎) won't be tried in the court of law, he and his wife held a press conference to express their disbelief and anguish.

Noriko Hidaka(日高 紀子) - Mother of the victim from Tokyo.

Kazuma Inoue(井上 一馬) - Medical expert at Kantō Medical University(関東医科大学) who made the decision that Asao Suetsugu(末次 朝雄) was unfit to stand trial for the murder of Naotarō Anzai(安斉 直太郎). Although he didn't reveal the specific evaluation he made for Mr. Suetsugu since the Tokumeigakari pair visited without a warrant, he did explain the general procedure all doctors go through when evaluating a patient for pre-trial cases. According to him, the doctor making the evaluation would look at

1. The patient's face and eyes
2. The patient's hospital and doctor visitation records
3. The patient's hospitalization records
4. The patient's unusual experiences
5. The patient's intention to commit suicide
6. The patient's non-social tendencies
7. The patient's tendency to commit violence to other people

Out of these, the doctor making the evaluation will take a close look at unusual experiences and treatment records by a doctor. Having a daughter murdered is considered an unusual experience.

Hirai(平井) - A doctor who works at Kyoto Rakusei Hospital(京都洛西病院 Kyōto rakusei byōin). His name was called over the intercom while the Tokumeigakari pair were visiting the hospital.
