Kazuyuki Izumi (泉一之, lit. Izumi Kazuyuki) is the father of Shinichi Izumi and husband of Nobuko Izumi. He is a former magazine writer, now freelance. 


Kazuyuki is a rather tall middle aged man. He has black hair that he keeps combed and sports a mustache. He's normally seen wearing a brown button up vest over a green long sleeved shirt and blue jeans.


In the beginning, Kazuyuki is a rather laid-back person, seeming to go with the flow with any changes he notices that take place in Shinichi. Later on, however, after Nobuko dies, he gets depressed and develops a drinking problem.


Kazuyuki is first seen late at night, entering his sons room along with his wife, after hearing strange noises. After witnessing his son on the floor, with a cord wrapped around his arm, he asks what he's doing. Shinichi quickly tells him of the '"snake" that jumped into his arm, and goes to show him the hole left from it. With no hole or any noticeable injury, Kazuyuki asks Shinichi if he's on drugs, something Shinichi denies and Nobuko laughs at.
