1st Seat: The Captain (Capitano) Position: Chief of Special Operations Responsibility: Handling major crimes, commanding field units He commands scenes that are difficult for regular investigation teams to handle, such as armed crimes and hostage situations.

He prioritizes not only the success of the mission but also the safe return of every team member. Attire: Black military uniform and coat.

2nd Seat: The Doctor (Dottore) Position: Director of the Forensic Science Research Institute / Chief Medical Examiner Responsibility: Forensic medicine, scientific identification, technical analysis of special cases A genius researcher who supports Fatui's scientific investigations. He handles cases that cannot be solved by general forensics alone, performing analysis of special substances, re-examination of evidence, and scientific verification of complex incidents. While his abilities as a researcher are extremely high, there are major issues with his sense of ethics and obsession with research. He does not hesitate to look for loopholes in regulations to achieve results. However, his forensic findings are often the deciding factor in solving cases. Attire: Military uniform based in white and blue with black arm covers.

3rd Seat: Damselette (Columbina) Position: Special Intelligence Analyst Responsibility: Interview analysis, behavioral psychology, information cross-referencing At first glance, she is a woman so gentle that it is a mystery why she is even in a police organization. However, she possesses an excellent ability to intuitively grasp the core of a case from fragmentary testimony or inexplicable behavior. During interrogations, she continues to listen to the other person's story quietly. That silence can actually make the other person feel more uneasy. She describes her own work as "just listening to stories." Attire: A white, cute, frilly nightgown-style military uniform.

5th Seat: The Rooster (Pulcinella) Position: Director of Personnel and Local Police Coordination Responsibility: Personnel, oversight of regional branches, coordination with the administration He appears to be a gentle old man, but he understands the interpersonal relationships and political power dynamics within the organization better than anyone. He has a strong influence on personnel transfers to regional branches and the placement of executives. He always wears a soft smile, but his decisions often change the power map of the organization. Who gets promoted and who is moved away from the center depends on his judgment. Attire: Military uniform based in blue.

6th Seat: The Balladeer (Scaramouche) Position: Chief of Inspection and Internal Misconduct Countermeasures Responsibility: Monitoring executives, investigating internal misconduct, exposing disciplinary violations One of the most troublesome figures for the executives, as he investigates misconduct within the police.

He is cynical and lacks cooperativeness, but he is highly competent in terms of not overlooking organizational corruption. Attire: Chinese-style military uniform.

7th Seat: Marionette (Sandrone) Position: Director of Technical Investigation and Mechanical Forensics Responsibility: Surveillance systems, mechanical forensics, digital investigation support The head of the technical department that develops special surveillance equipment, unmanned investigation devices, and evidence preservation systems.

He is responsible for cases involving money, such as money laundering by criminal organizations, shell companies, slush funds, and illegal transactions.

Attire: Layered black military uniform.

11th Seat: Childe (Tartaglia) Position: Mobile Investigation Team Leader / Field Operative Responsibility: Initial response to violent crimes, tracking, execution of arrests He is the most field-oriented among the Harbingers.
