191 cm. The director of the Nightglow Detective Agency. He is well-liked by everyone at the agency. He has an elusive, aloof personality. He doesn't possess a Detective Special Ability and isn't a Master Detective like Halara and the others, but the fact that he is recognized by the World Detective Organization suggests he is an excellent detective. First person: I (casual/rough)

He has a calm and kind personality; in a word, he's a "pushover." He mostly uses polite speech, but he doesn't use it with close friends like Desuhiko. He can go to the Mystery Labyrinth using Shinigami's power and can use other people's Detective Special Abilities together with them. First person: I (soft/polite) 150 cm.

181 cm. 63 kg. They keep a photo of a cat hidden in their clothes. Their special ability is "Postcognition." It was originally a common type of psychometry, but through blood-soaked training to make it a more effective ability for a detective, they manifested this version in just three days. Through Postcognition, they can see the state of a murder scene at the moment of its first discovery. The effective range is about a 10-meter radius centered on the corpse. This allows for the investigation of scenes that have been cleaned up or cold cases. On the other hand, to perform Postcognition, they must meet the conditions of "standing at the crime scene" and "knowing the victim's name and face." Additionally, at present, they cannot see living creatures other than the corpse through Postcognition. It also seems to be a hassle that they have to verbally explain what they saw in the past to others. Their hands are slender, small, and soft. First person: I (neutral/polite)

A show-off who loves women. When he goes out, he hits on women under the guise of "investigation" and even makes a list of them (though he does actually investigate). First person: I (casual/childish) 153 cm.

180 cm. She moves entirely at her own pace and is an extreme airhead. She "forgets the digits of numbers she doesn't use often," perceives words with similar sounds as having the same nuance, uses words in her dialogue that are slightly off, makes ominous remarks without malice, and her imagination often leaps in bizarre directions. She is emotionally expressive and honest. First person: I (formal/feminine) Second person: ~san

196 cm. His catchphrase is "I want to die someday." He speaks slowly and sometimes uses poetic metaphors. First person: I (polite/reserved) Second person: you (soft) / ~kun
