Background / History

An Xiao enrolled at Tokyo Metropolitan Advanced Nurturing High School as a Class B student. Initially uneasy about the school’s unusually generous promises, he chose to adapt gradually while observing his new surroundings and classmates. He met Kikyo Kushida before the entrance ceremony, then became acquainted with Soh Shibata and his seatmate, Honami Ichinose. 2

He was among the first new students to notice upperclassmen’s class-point rankings. During Hoshinomiya’s orientation, he directly questioned the purpose of class points and the ranking system, drawing attention to the school’s concealed rules. 4 He later reasoned that the advertised 100% advancement and employment rate was likely reserved for Class A, with the other classes competing to reach it. 5

By recording a conversation with an upperclassman in the cafeteria, An Xiao acquired substantial information about the school’s class competition, point economy, and risk of expulsion. Chairman Sakayanagi noted that he had extracted the rules through verbal maneuvering unusually quickly. 6 7 An Xiao shared the recording with Ichinose and Class B, contributing to their early preparation and cooperation. 6 12

He accepted a private arrangement with Chie Hoshinomiya: in exchange for 20,000 points per month and potential bonuses, he would monitor and oppose Class D during exams and school events while pursuing Class B’s advancement. He deliberately limited his commitment to formal competitive settings rather than daily interference. 10

After witnessing an argument between Manabu and Suzune Horikita, An Xiao sold a photo of the siblings to Manabu for 500,000 points. Manabu subsequently hired him to guide Suzune and watch over her, paying 100,000 points monthly as long as the arrangement remained in effect and did not harm Class B’s interests. 13 14 Manabu also recruited him into the Student Council, where An Xiao handled administrative work and was later considered for promotion to secretary. 17 19 35 50

Appearance

An Xiao is tall and slender, standing at approximately 176 cm. He has a refined face and long, messy hair that frequently falls over his eyes, contributing to his habitually tired appearance. 6

• Long, disheveled fringe that obscures his eyes.
• Fair complexion; blushes noticeably when embarrassed. 9
• “Lifeless” or weary-looking eyes despite his youthful features. 6
• Often seen with candy or a lollipop in his mouth. 16

Personality

An Xiao is intelligent, skeptical, and highly observant, but fundamentally passive. His admissions evaluation describes him as someone who completes assigned work well yet avoids excessive effort in competition unless it affects him personally. He nevertheless tends to help friendly people and friends in trouble. 4

He prefers an ordinary, low-effort school life and frequently complains when dragged into complicated situations. Despite this, he is practical when incentives are involved and readily recognizes the value of information and points. 6 10 11

His bluntness can make him appear detached, particularly in his refusal to solve Class D’s problems for free. However, he keeps promises, reassures others when they are distressed, and acts decisively when someone is in danger. 40 47 He is also notably uncomfortable with unwanted physical closeness and values his personal space. 9 44
