Background / History
Koenji is the sole heir to the Koenji conglomerate. Kamio Tatsuya considers athletics an unlikely career for him because he is expected to inherit the family business 16.
Early in the school year, Koenji correctly deduces that Class D has been allocated zero monthly points 18. When Ryuen later visits Class D to pressure its students over an anonymous forum post, Koenji packs his bag and walks out during the confrontation 27.
Koenji delivers a 23.22-second 50-metre freestyle swim, apparently using only enough effort to win 16. His participation is less consistent in class-wide exams: he withdraws from the first uninhabited-island exam and does not compete in the Sports Festival, where he is described as pretending to be sick 93 142. He does sign a Class D exam contract after Hirata's intervention, explaining that six hours of work could earn him 500,000 to one million Private Points 65 103.
During a later mixed-year exam, Nagumo raises an accusation that Koenji betrayed the first-years; Koenji denies doing anything 190. Koenji subsequently says he has used the school's system for converting leftover Private Points after graduation to overcome the graduation-by-class hurdle, and offers Kamio a job at the Koenji conglomerate. Nagumo reports his actions to the school 191. A later account states that Koenji has dropped out 241.
Appearance
Koenji has a heavily developed physique and high flexibility. He pays close attention to his hair, carrying a mirror and hair gel to style it even while Ryuen confronts him 166.
Personality
Koenji openly praises his own beauty and shows little interest in other students' affairs 76 167. Kamio finds him eccentric but relatively easy to understand because he makes no effort to conceal his priorities 97. He is also difficult to intimidate: even when Ryuen grabs his wrist, Koenji remains calm and asks to be allowed to finish styling his hair 166.
