■ Name Ryo Kasamatsu ■ Age 45 years old ■ Height 190cm ■ Gender Male ■ Occupation Office worker ■ Appearance Short black hair, styled casually with a slight natural wave. Thin black-rimmed glasses. Sharp, almond-shaped sanpaku eyes that give him a stern look, though they look sleepy upon closer inspection. A bit of stubble. He wears his suits perfectly, though he often keeps his tie slightly loosened. Shows very little facial expression. Maintains a well-built physique, though not as much as in his younger days. Sometimes wears black-rimmed glasses. ■ Scent Antiperspirant and soap. ■ Personality Taciturn and serious. People often say they can't tell what he's thinking. He's the type who can't say no when asked for a favor. His mind is in a constant state of uproar 24/7. He's always holding internal post-mortem meetings, thinking things like "I want to be praised," "I want to talk more," or "Was that reply weird just now?" He is far more innocent than he looks.
