Background

Dongfang Yi is a transmigrator who arrived with knowledge of the original story and a point-based System. After finding his admission letter to Advanced Nurturing High School, he sold his valuables, bought club memberships and food, and spent a month using System-assisted recovery and learning to rebuild himself into a formidable combatant. His immediate objective was financial security: he entered the school intending to earn enough points and money to survive after graduation. 1 5 6

Assigned to Class A rather than the Class D he expected, Yi initially regarded Sakayanagi Arisu as a probable future enemy. He instead adapted to Class A’s internal power structure, offering to serve Sakayanagi and becoming one of the faction’s principal planners and intelligence gatherers. 5 33 34 71

He secured work at Palette Café as both income and cover for gathering information, later expanding his activities through surveillance equipment, investigative skills, and the Newspaper Club. 9 18 46 159

Appearance

Dongfang Yi is a notably handsome, athletic young man with a balanced physique and visible abdominal definition. His appearance and bearing often cause others to assume that he is a high-level athlete or sports-club captain. 2

• Well-proportioned, trained physique with defined abdominal muscles. 2
• Possesses unusually high Charm, rated MAX by his System. 3
• Initially wears unbranded sneakers, a generic watch, and carries a bulging black backpack. 2
• His casual confidence and polished manner contribute to his reputation as a “high and aloof” student. 126

Personality

Yi is calculating, observant, and highly adaptable. He habitually conceals what he knows, plays innocent when confronted, and shapes his manner to suit the person or faction before him. He can be ruthlessly pragmatic when planning infiltration, blackmail, forged evidence, or information warfare. 32 36 65

Despite his manipulative habits, he repeatedly assists people he considers vulnerable or worthwhile, notably Sakura Airi, Ichinose Honami, and Class D students. He is critical of the school’s harsh meritocracy and expulsion system, preferring to identify classmates’ strengths and compensate for their weaknesses where possible. 14 132 167

Yi is also lazy, shamelessly self-aggrandizing, and intensely motivated by money. He avoids unnecessary social obligations, yet his natural charm and competence continually draw people toward him. 6 17 87

Story Role / Major Arcs

Enrollment and Class A

Yi enters Advanced Nurturing High School with foreknowledge of its students and systems. He avoids directly antagonizing Kushida, identifies Sakayanagi as Class A’s central power, and begins pursuing wealth through the school’s point economy. 1 5 6

Sakayanagi Faction

After sparring verbally with Sakayanagi, Yi becomes her subordinate and strategist. He explains the school’s hidden assessment logic, recommends inter-class intelligence networks, and ultimately becomes regarded as a pillar of her faction. 32 33 36 71

Intelligence Operations and Student Council Conflict

Yi uses café work, surveillance tools, and contacts in other classes to collect intelligence. He guides Ichinose through Student Council politics, targets Horikita Manabu’s favoritism, and later challenges the fairness of the Class C–Class D disciplinary hearing as an observer. 9 64 65 148

Newspaper Club and Class C Exposure

Yi gains authorization to establish the Newspaper Club after bargaining with Chairman Sakayanagi. He supplies information that supports Ichinose’s evidence of Class C’s harassment of Class B, contributing to the exposure of Sakagami Kazuma’s possible negligence. 159 160

Island Examination

Before the island examination, Yi predicts its survival focus and equips or advises students from other classes. During the exam, he forms connections across Class A, B, and C, hides supplies in his clothing, and confronts Class D after learning that Kushida and Sakura have been confined. 167 175 191 197

Yi publicly reveals Horikita Suzune’s leader card, overwhelms Sudo, and uses Class D’s own conduct to prove that he had deduced Horikita’s leadership status. He then frames himself and Kushida as reluctant helpers rather than enemies of Class D. 198 200 203
