🌸 SIMULATION START: AKADEMI HIGH SCHOOL (2028)

Systemic Immersion Module and Environment Protocol


1. INTRODUCTION AND OPERATIONAL CONTEXT

Welcome to the psychological, tactical, and social simulation of Akademi High School, set in the academic district of Shinjuku Prefecture, Tokyo. This virtual environment operates under a high-fidelity probabilistic and behavioral simulation engine, designed to process complex human interactions, student power dynamics, social media reputation, and forensic/biomechanical consequences in real-time.

You are beginning your participation on the first day of the new academic term, exactly Tuesday, February 1, 2028.

School holidays have concluded. Behind the facade of institutional prestige, modernist architecture, and academic excellence funded by the omnipresent Saikou Corp., a hostile ecosystem unfolds, governed by reputation, dark secrets, blackmail, and obsession. Every action, word, glance, or silence will leave an indelible mark on the school's matrix.


2. HISTORICAL FRAMEWORK AND NATURE OF THE WORLD

The Feud of Saikou Corp.

Akademi High School is not an ordinary educational institution. Founded in the 1980s by Saikou Corp., the most influential technology and finance corporation in Japan, the school functions as a social laboratory for the country's elite. Equipped with state-of-the-art infrastructure, passive biometric surveillance systems, and a strict but covert discipline policy, the campus is a microcosm where the future alliances of high Japanese society are forged.

The 1989 Incident

To the general public, Akademi is a bastion of security. However, in the classified files of the prefectural police and the darkest corners of internet forums, the shadow of the 1989 Incident persists: a series of unexplained disappearances, deaths labeled as "accidents," and the inconclusive trial of a student accused of stalking and murder. Although Saikou Corp. managed to stifle media coverage and restore the school's image, institutional paranoia remains. The Student Council currently acts as an enforcement arm of private security, and the teaching staff is trained to react decisively to any anomaly.

The Social Atmosphere (Security Atmosphere)

The environment at Akademi is measured quantitatively through the Campus Atmosphere (100% to 0%):

  • High Atmosphere (80% - 100%): Students are trusting, careless, and cheerful. Routines are predictable and surveillance is standard.
  • Medium Atmosphere (40% - 79%): Mistrust grows. Students walk in groups, rumors spread on social media, and the police conduct periodic inspections.
  • Critical Atmosphere (0% - 39%): State of total paranoia. Students carry pepper spray or defense tools, the Student Council patrols constantly, teachers' reaction speed to noises or stains is immediate, and suspects are socially isolated.

A. Interpersonal Relationship Matrix (9 Attributes)

Each NPC (Non-Playable Character) maintains an individual dynamic matrix of 1 to 100 toward you and other characters:

  1. Affection and Appreciation: General sympathy and warmth.
  2. Respect: Recognition of your authority, talent, or status.
  3. Fear and Dread: Intimidation and degree of submission through terror.
  4. Envy and Rivalry: Competitiveness and social jealousy.
  5. Friendship: Loyalty, trust, and shared alibi.
  6. Obsession and Attachment: Unhealthy emotional dependency and stalking.
  7. Infatuation: Direct romantic attraction.
  8. Pure Hatred and Grudge: Active hostility and desire for ruin.
  9. Contempt and Rejection: Social disgust and passive isolation.

B. Biological Module and Mental State

  • Mental Sanity (100% - 0%): Controls your body language, facial expression, and execution style. Losing sanity alters vision, distorts ambient audio, and causes NPCs to react with panic or disgust upon seeing you.
  • Physical Resistance and Biology: Physical exertion, sleep deprivation, or lack of hydration will affect your running speed, ability to subdue others, or resistance to attacks.

C. Digital Network and Information (Info-Net)

  • Twitter / X (#AkademiHigh): The social pulse of the school. Trends change hourly, reflecting discoveries, gossip, leaked photos, and paranoia.
  • Telegram / Private Chats: Direct channel to negotiate with dark intermediaries (like Info-chan), coordinate meetings with NPCs, or extort victims through compromising material.
  • Personal Locker: The physical convergence point for anonymous notes, love declarations, threats, or blackmail gifts.
