Biodata

Feature	Value
Name	Orikasa Yuu (折笠悠)
Gender	Male
Affiliation	Advanced Nurturing High School; Class D 2
Occupation/Role	First-year student; self-described adherent of the Energy-Saving Ideology 1
First Appearance	Chapter 1, “Energy-Saving Ideology of the Max-Level Individual” 1

Background

Three days before arriving at Advanced Nurturing High School, Yuu lived an ordinary life in another world. Following an accident, he awakened on a bus bound for the school with unfamiliar status data embedded in his consciousness and memories concerning the institution. 1

He recognized Class D as a place where the school gathers students with problems or character flaws. Rather than resent the assignment, he judged its lack of expectations and attention to be ideal for remaining unnoticed. 2

Appearance

Yuu usually presents himself as an expressionless, low-profile student in a loose uniform. His max-level physique becomes conspicuous when exposed, undermining his efforts to avoid notice. 7 8

• Extremely lean, symmetrical, and balanced musculature rather than bulky gym-built muscles. 8
• Sharp shoulders, back, waist, and abdomen described as having no visible excess or weakness. 8
• Moves with minimal, highly precise adjustments; he evades Ryuuen Kakeru’s descending hand by shifting his shoulder only half an inch. 9

Personality

Yuu organizes his life around the Energy-Saving Ideology: avoid unnecessary actions, complete necessary tasks quickly, and prevent later “maintenance costs.” He treats social interaction, attention, and unresolved problems as expenditures to be minimized. 1

His detachment is pragmatic rather than wholly uncaring. He helps Sakura Airi when her panic risks escalating into a larger scene, warns her about the dorm key loophole before it can create problems, and pays to secure his own room against future intrusion. 1 5

Yuu prefers observation to confrontation. He assesses people by their potential energy cost, keeps distance from individuals he considers dangerous or demanding, and uses information gaps to escape situations where direct conflict would create greater consequences. 2 4 9

Observation and Analysis

Yuu continuously gathers practical information without drawing attention to himself, using peripheral vision, environmental details, and timing calculations.

• Identifies surveillance blind spots and exit layouts during the opening ceremony. 2
• Notices complete camera coverage around the supermarket and declines to intervene in Sudou Ken’s confrontation because of the expected aftermath. 4
• Detects that Class C’s corridor cameras have been covered and calculates that seventy-three minutes have elapsed since the last security patrol. 9
• Uses this information to make Ryuuen reconsider attacking him. 9

Conflict Avoidance

Yuu does not seek physical confrontations despite his combat parameters. His preferred method is to make intervention unnecessary or to use knowledge that raises the opponent’s risk.

• Untangles Sakura Airi’s camera strap in four seconds, preventing her distress from becoming a larger public incident. 1
• Avoids helping Sudou during an upperclassman confrontation because surveillance footage would lead to investigations and further attention. 4
• Counters Ryuuen’s intimidation by exposing the risks of the covered cameras instead of threatening him directly. 9
• Treats physical force as a last resort when information can achieve the same result at lower cost. 9

Preventative Planning

Yuu is willing to spend points or make brief interventions when doing so eliminates a more costly future problem.

• Learns that any student can obtain a spare key to another student’s room for 200 points without consent. 5
• Warns Sakura Airi to reinforce her door or purchase an independent lock. 5
• Pays 2,000 points to prevent anyone—including school management—from claiming the spare key to his room unless he is personally present. 5

Equipment and Resources

• School-issued smartphone — used for point payments, Class D’s group chat, and contact exchanges. 3 5 9
• Private dormitory room — its spare-key claim rights are locked down after Yuu pays 2,000 points. 5
• Personal points — retains a balance of 97,180 points immediately after securing his room. 5

Relationships

• Sakura Airi — Class D classmate. Yuu untangles her camera strap on the school bus, warns her about the spare-key policy, and accepts the lunchbox she prepares as thanks. 1 5 6
• Ayanokoji Kiyotaka — Classmate and fellow observer. Yuu recognizes Ayanokoji’s abnormal awareness and actively avoids becoming a subject of his attention. 1 3 8
• Horikita Suzune — Class D classmate seated beside him. Yuu considers her driven isolation an individual choice and decides not to interfere with it. 2 9
• Kushida Kikyo — Classmate who adds Yuu to the Class D group chat and exchanges contact information with him. 9
• Ryuuen Kakeru — Class C’s tyrannical leader. After Yuu uses surveillance information to avoid a confrontation, Ryuuen becomes interested in him. 9
• Koenji Rokusuke — Classmate who openly acknowledges Yuu’s physique as an innate “completed form.” 8

Story Role / Major Arcs

Enrollment and Class D

Yuu arrives at Advanced Nurturing High School intending to remain invisible. On the bus, he assists Sakura Airi with her tangled camera strap but deliberately avoids conversation or further connection. He later views Class D’s marginal position as advantageous for his low-profile lifestyle. 1 2

Early Campus Routine

After receiving 100,000 points, Yuu remains indifferent to the class’s excitement and spends only on necessities. He purchases the cheapest available toiletries and bread, investigates the dormitory key policy, and determines that no club is compatible with his energy-saving lifestyle. 3 4 5

Class D Social Incidents

Yuu accepts Airi’s homemade lunchbox as repayment for his earlier help, then leaves the classroom to end the attention generated by Hasebe Haruka’s teasing. During Sotomura Hideo’s betting pool involving the Class D girls, Yuu neither participates nor watches, which reassures Airi. 6 7

Swimming Class

Yuu’s max-level body attracts attention during the first swimming class despite his attempt to remain unnoticed. Koenji recognizes its unnatural balance, while Ayanokoji studies it as an unknown variable. 8

Encounter with Ryuuen

Yuu witnesses Ryuuen enforcing control over Class C through violence. When confronted, he reveals that Ryuuen’s camera sabotage leaves evidence and that a security patrol is approaching, causing Ryuuen to withdraw rather than attack. 9
