Inori Kosaka is a master detective of Coffin Robin, a genius of "Detection," and a former university associate professor specializing in criminal psychology. He still maintains a deep interest in heinous crimes. His behavior is elegant and calm, and he often wears a charming smile, though some find him suspicious. He excels at reading the psychology of those he faces. Perhaps due to the aftereffects of a past incident, his body is not strong, and he occasionally collapses from seizure-like episodes. 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 is a master detective who knows crime more deeply and broadly than anyone else. His name is read as Inori Kosaka. Height: 178cm, Age: 29, Birthday: August 11th.
