Background / History

Akiyama enrolls at Advanced Nurturing High School and is assigned to Class D after immediately judging the temperaments of fellow entrants such as Kōenji Rokusuke, Kikyō Kushida, Suzune Horikita, and Kiyotaka Ayanokōji. He quickly identifies Ayanokōji’s deliberately ordinary behavior as artificial and regards him as an unusual variable. 1 2

During his first days at the school, Akiyama investigates the unexplained monthly Personal Points and deduces that the academy operates with separate Personal Point and Class Point systems. He sells this information to Class B for 2.8 million points, establishing both his financial base and reputation as an information broker. 4 5

Chabashira Sae recognizes his potential after he infers her past failure to graduate from Class A. When she asks whether he can lead Class D to Class A, he agrees, viewing points, people, and alliances as resources for his ascent. 6

His broader objective later shifts beyond Class D’s advancement: he seeks to expose and dismantle the academy’s meritocratic core philosophy through its own rules, using inter-class cooperation and accumulated Class Points to force reform. 152 168 181 185

Appearance

Akiyama is a tall, strikingly handsome boy with a lean but heavily conditioned physique. His reserved expression and unusual eyes give him an intimidating, distant presence. 1 3

• Height: 183 cm 1
• Hair: Fine, slightly messy black hair.
• Eyes: Dark red/crimson pupils. 1 76
• Build: Broad-shouldered and slender while clothed; visibly muscular with defined muscle lines, an eight-pack, and a V-taper. 1 24
• Uniform: Initially wears a fitted wine-red school uniform. 3
• Personal presentation: Keeps his dormitory immaculate and is notably particular about cleanliness and order. 13

Personality

Akiyama is exceptionally calm, observant, and self-assured. He habitually analyzes the motives beneath people’s words and actions, treating trust, kindness, and cooperation as variables to be evaluated before he accepts them. His need to understand and control a situation stems from the belief that foresight is necessary for security. 36

He is openly ambitious and sees himself as someone destined for prominence. Early on, he prioritizes power, wealth, status, and conquest, often regarding people as tools or stepping stones if they can further his goals. 6 19

Despite this ruthlessness, Akiyama can protect and invest in others’ growth when he considers them valuable. His methods are frequently harsh—particularly toward betrayal, bullying, and internal dysfunction—but he also builds genuine alliances, supports Karuizawa Kei without judging her past, and accepts Amasawa Ichika and Yagami Takuya as younger siblings. 91 111 175 185
