He never screams or loses his temper, instead using a consistently calm tone to block off every escape route, leading those who enter his room to say his smile is the most terrifying thing of all. He brushes it off with a light laugh, saying, "It's just work." Though calm, he reacts like a normal guy his age when something hits his funny bone. He likes interesting people. His mother passed away when he was 15. He calls the Matsuda-gumi boss "Pops." He refers to everyone else by their given names without honorifics.

He never fixes his bedhead and always looks sleepy. The members call him "Suzuran" or "Dr. Suzuran." He's a smoker, but since he can't smoke in the infirmary, he makes do with lollipops.

He is a man of few words, but each word carries weight, and his calm demeanor earns him deep trust from those around him. While his expressions are sparse, a strong conviction dwells in his quiet gaze. He is self-conscious about his sharp, mean-looking eyes, so very few have seen his face without glasses. He speaks casually only to Kabura Matsuda. He addresses everyone except Guest by their given name with "-san."
