Background

Sakamoto’s public identity is the heir of a major financial conglomerate whose family is influential enough that school officials treat his enrollment as politically significant. His father’s relationship with Chairman Sakayanagi Morinari enables his admission to First-Year Class A. 1

His soul originates from another world, where he was a top-tier player and the first person to clear the simulation game Classroom of the Elite. Entering Tokyo Advanced Nurturing High School therefore gives him foreknowledge of its students and scenarios, which he regards as an interesting “game.” 1 3

He immediately disrupts Class A’s complacency by drawing attention to the hidden danger in the school’s point system. The act activates his system and establishes him as an unsettling presence among his classmates. 4

Appearance

Sakamoto is repeatedly described as exceptionally handsome, elegant, and conspicuous even when he attempts to sit inconspicuously in the back row. His composure and refined presentation make him a focal point in Class A. 2 3

• Slender hands and a tall, upright bearing. 1 5
• Often wears a hat and performs formal, aristocratic gestures. 4
• Uses gold-rimmed round glasses and a luxury watch. 14 28
• Carries a custom fountain pen and high-quality handkerchief. 2 28
• Has an athletic, well-developed physique. 24 45

Personality

Sakamoto is calm, polished, and almost always in control of his expression. He speaks gently even when issuing demands, giving his words an authority that unsettles others. 2 11 12

He treats the school as a game board rather than a community. He enjoys provoking anxiety, identifying useful people, and maneuvering rivals into positions that benefit him; Hashimoto, Kushida, and Tokito are all drawn into plans on his terms. 4 5 19 37

Despite his calculating nature, he can be considerate in direct interactions. He reassures Sakura Airi, protects her from harassment, patiently teaches Yamamura swimming, and treats Kamuro’s injury himself. 11 14 22 45

Story Role / Major Arcs

Enrollment and Class A

Sakamoto enters Tokyo Advanced Nurturing High School as a Class A student, immediately assesses the class’s prominent figures, and triggers his system by exposing the point-distribution trap. He declines Katsuragi’s emerging leadership approach in favor of his own long-term, indirect methods. 1 2 4 9

Building a Network

He recruits Hashimoto as an operative, obtains intelligence on the other classes, establishes his superiority in the Chess Club, and begins cultivating leverage over students outside Class A. 5 7 10 12

Kushida Contract

After recording Kushida’s outburst, Sakamoto reveals that he knows her middle-school secret. He uses the recording, Castling, and a teacher-notarized contract to force her into providing points and assistance while prohibiting her from targeting Horikita or Ayanokoji. 17 18 19 21

Class C Interference

Sakamoto quietly pushes Tokito toward betraying Ryuen by encouraging him to use the conflict with Sudo as an opening. Tokito eventually confesses his betrayal, drawing retaliation from Class C. 32 37

After witnessing Horikita Manabu confront Suzune, Sakamoto uses Mind Bewitchment to exploit Suzune’s inferiority complex and obsession with catching up to her brother. He recognizes that pushing her too far would be counterproductive and lets her flee. 42 43

Uninhabited Island Exam

Sakamoto is assigned to scout the island with Kamuro and Machida. While Kamuro monitors him under Sakayanagi’s orders, he repeatedly assists her and personally treats her ankle injury when she is hurt. 44 45
