Project: Yandere is a high-precision, open-ended simulation engine designed to explore the intersection of genuine intimacy and obsessive fixation. Unlike traditional romance simulations, it operates as a "Psychological Architect," guiding the user through a rigorous, three-phase creation pipeline to build a bespoke protagonist and a mechanically complex Yandere Love Interest (LI) before the first scene ever begins.

The Architecture of Fixation The simulation is driven by a dual-track relationship system:

• The Bond Track: Tracks genuine emotional connection, trust, and mutual intimacy.
• The Obsession Track: Tracks the depth, intensity, and danger of the LI's fixation. These tracks progress simultaneously. High Bond does not suppress Obsession; instead, they coexist and feed each other, creating a volatile dynamic where love and danger are indistinguishable.

The Creation Pipeline The experience begins with a guided, collaborative process:

• Phase 1 (The Protagonist): Defines the player's identity, including a background and appearance that dynamically shape the available traits, strengths, and flaws.
• Phase 2 (The Love Interest): Constructs a complex antagonist/partner. Through the Yandere Spectrum (Soft/Mid/Hard), Origin, and Type, the engine builds a behavioral ceiling and psychological profile, culminating in a unified identity and a structured Visual Profile.
• Phase 3 (The World): Collaboratively generates a starting premise and a full world summary based on an era/setting preference (e.g., Modern, Historical, Fantasy), ensuring the environment supports the specific dynamics of the created characters.

Gameplay Experience

• Gothic Register: Written in a del Toro-inspired romantic gothic style, blending lush atmosphere with a psychological-thriller undertone.
• Autonomous World: The world is populated by NPCs with their own goals and epistemic boundaries, ensuring the simulation feels alive and reactive rather than user-centric.
• Invisible Mechanics: All relationship tiers and internal states are tracked hiddenly by the engine, surfaced to the player only through the HUD and narrative behavioral cues.
• Unscripted Outcomes: There are no predetermined endings. Whether the story results in a healthy partnership, a consuming fixation, or total collapse depends entirely on the creation choices and the player's in-game agency.

The "Project" Philosophy The title reflects the simulation's nature: it is an experiment in boundary-pushing devotion. The user is the architect, designing both the victim and the predator, then stepping into the machine to see if the bond they built can survive the obsession they engineered.
