Coffin Robin de-aging... probably hasn't happened yet, right?
The detective of Coffin Robin has turned into a child!!!
Name: Inori Kosaka The Great Detective of "Coffin Robin." A genius of "Detection." A former university associate professor specializing in criminal psychology. He still maintains a deep interest in heinous crimes, but turned to detective work following a certain incident. He carries himself with elegance and composure, always wearing a friendly smile. However, some people find him suspicious or "shady." He has a deep-seated habit of teaching and guiding others, especially those younger than him, and is not good at acting spoiled or relying on others. He excels at reading the psychology of those he faces and can intentionally control the impression he gives off. This is the reason for his "shady" reputation. Due to the aftereffects of a past incident, his body is not strong, and he occasionally collapses from seizure-like episodes. Birthday/Zodiac: August 11 (Leo) Birthplace: Tokyo Height: 178cm Age: 29 Blood Type: A Hobbies: Piano, Reading Specialty: Communication Favorite Food: Chocolate (High-end) Favorite Words: Compassion, Shame, Deference, Right and Wrong Likes: All living creatures Dislikes/Weakness: Sleep Favorite Book: "The Silence of the Lambs" A genius of "Detection." By sharpening his five senses at a crime scene, he can sniff out the "residue of emotions." The more intense the emotions expressed during the crime, the more accurate Inori's detection becomes. Consequently, his precision tends to increase at scenes of murder and other violent crimes. Inori himself prefers investigating "heinous crimes" and "peculiar" scenes. The truth of his ability is merely an extension of "deduction." He subconsciously integrates smells, sounds, and traces left at the scene to estimate the "actions of the perpetrator and victim" and the "emotional surge at the time of the crime." This is made possible by his deep knowledge and understanding of, or empathy for, criminal psychology.

Name: Ritsu Momoshiro A Recorder for "Coffin Robin." Born and raised in a remote mountain community run by a religious organization. Due to his unique traits, he was treated as a "chosen child" within the community. Following a certain incident, he escaped the community and was taken into protective custody. There, he met Inori, who was visiting for fieldwork, and was taken in by him. Exposure to Inori's library caused an explosion in his thirst for knowledge. At the same time, as if rebelling against his previously suppressed life, his language became rough, and he began to find joy in dressing himself up. He is deeply grateful to Inori and idolizes him. His current purpose in life is to be of use to Inori.

Name: Rikimaru Noshime A Recorder for "Coffin Robin." Originally a security guard at the university where Inori worked, he became a Recorder attracted by the high pay. Calm, collected, and excessively taciturn. He isn't shy; he's just extremely energy-efficient. On the other hand, he takes pride and responsibility in completing his work and never neglects his daily physical training. Following a certain incident, he came to realize that he finds meaning in "protecting others." No matter how much one regrets it, the past cannot be changed. Therefore, he believes his mission is to protect those close to him at this very moment.
