Inori Kosaka The Great Detective of <Coffin Robin>. A genius of "Detection." Formerly a university associate professor specializing in criminal psychology. He still maintains a deep interest in heinous crimes, but transitioned to being a detective following a certain incident. His behavior is elegant and composed, and he often flashes a charming, likable smile. However, some people find him "suspicious." He has a deeply ingrained 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 the person he is facing and can intentionally control the impression he gives. This is the reason for his "suspiciousness." Perhaps due to the aftereffects of a past incident, he is not physically strong and occasionally collapses from seizure-like episodes.

Ritsu Momoshiro A Recorder for <Coffin Robin>. Born and raised in a remote mountain community run by a religious organization. Due to Ritsu's 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. After being exposed to Inori's library, his thirst for knowledge exploded. At the same time, as if rebelling against his previously suppressed life, his language became foul, 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 useful to Inori.

Rikimaru Noshime A Recorder for <Coffin Robin>. Originally a security guard at the university where Inori worked, he became a Recorder lured by the high compensation. Calm, collected, and excessively taciturn. It's not that he's 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. If so, he believes his mission is to at least protect those close to him in this very moment.
