He is described as a tall boy, with being as tall as Ken Sudō. He is good-looking and described by Chie Hoshinomiya as a "cool guy" at first glance.

Personality
Kyō is a mysterious person. He appears like he wants to help Kiyotaka Ayanokōji through calling him and even appearing at the door of his dorm. It is unclear what he actually wants or what is his background, but he is described as king figure of his class, much like a controller. He is self-serving and categorizes people as friends and foes by judging them through their activities. He shows no mercy to his foes. According to Ryūji Kanzaki, he has a deep respect for Professor Ayanokōji and has talked with him multiple times. Though he appears as a king figure, he doesn't like to become the center of attention, and often assigns Osamu to take the role of the leader. He has a similar ideology as Kiyotaka Ayanokōji as both strive for a normal high school life.

Background
Ishigami has met Arisu Sakayanagi, Ryūji Kanzaki and Professor Ayanokōji on multiple gatherings organized by renowned and rich families. He has developed admiration for Professor Ayanokōji through this and likes to talk to him. According to Ryūji Kanzaki, him and Kyō attended the same academy.

Plot
In the third term of Kiyotaka Ayanokōji's first year in the Advanced Nurturing High School, Kyō called him at 1 in the morning. The call was short and mysterious, where Kyō mentions Kiyotaka Ayanokōji's full name and then, hangs up. Kiyotaka Ayanokōji deduces this as a warning from his father. Some months later, when Kiyotaka Ayanokōji's first year is over, Kyō enrolls as a freshman in the Advanced Nurturing High School where Kiyotaka Ayanokōji is a second year. When Takuya Yagami was explaining Kiyotaka Ayanokōji about the special exam for expelling him, he also mentioned that Kyō had shown up to the student council room as the representative of the Class 1-A. When Suzune Horikita went to the cruise ship's private pool to look for a letter similar to the one she found on the note, Kyō arrived to make a reservation. When Suzune Horikita checked his handwriting and it was similar to the one she was looking for, she became highly suspicious of him. Suzune Horikita tried to start a conversation with Kyō and was surprised when he spoke out to her by saying her name, he later on says that he had memorized the names of all the outstanding students in the second year. Suzune Horikita began to wonder if Kyō was hiding his true abilities like Kiyotaka Ayanokōji. Later on, when Mio Ibuki makes it clear that Kyō is physically weak and is of a bad physique, Suzune Horikita assumed Kyō as innocent. During the Sports Festival of the 2nd year arc, Kyō goes to the door of Kiyotaka Ayanokōji's dorm. When Kiyotaka Ayanokōji is about to open the door, Kyō asks him to stay where he was and listen to him. He makes it clear to Kiyotaka Ayanokōji that he is neither a friend nor a foe and had just come to give an advice. As advice, he advises Kiyotaka Ayanokōji that to live a normal high school life, he would have to first get rid of Tsukishiro and then the other White Room students, and the peace would return. He further asked Kiyotaka Ayanokōji to be on a "look out" if he wants to stay in Advanced Nurturing High School till graduation. When Kiyotaka Ayanokōji wonders why Kyō is advising him, Kyō adds that his presence was having a negative impact and he just wanted to prevent it from having, implying that Kiyotaka Ayanokōji's actions were catching attention. His voice trails off as he says this. Apparently, he didn't want to stay long, and it could be assumed that he had left by then.

Abilities
Kyō is regarded as a genius by Ryūji Kanzaki. His thinking abilities far surpass Ryūji Kanzaki. His academic ability and his position as the dominant in his class proves this. However, his physical rating is poorly rated and he isn't known to be indulged in any kind of physical training.
