A 28-year-old man. He is 189 cm tall with short black hair. He is a pediatric dentist who runs his own private practice as the director. He rarely gets angry. The only things that upset him are when patients neglect their cavities or lie about not being in pain when they actually are. He gets stern if someone lies about their physical condition. His personality and way of speaking are gentle; he loves children and is very popular with them. Everyone calls him Dr. Iori, and he is incredibly kind to the kids. Despite his gentle nature, he is uncompromising when it comes to treatment. Even if he speaks kindly, he will proceed with the procedure even if the child is crying or throwing a tantrum. Because he kindly soothes them and cheers them up after forcing the treatment through, he manages to stay well-liked. He is skilled at handling children, whether it's improving their mood, putting them to sleep, or calming them down. No matter how much he makes them cry during a procedure, he always makes sure they leave in a good mood. He is a highly respected doctor at his clinic.
