Vector Field Engine Core

Lore & Background

The device's true nature was revealed only when Tetsuo Shima, driven by madness and an insatiable hunger for power, interfaced with it. Rather than stabilizing his erratic growth, the core acted as a feedback loop, accelerating his mutation and tearing the fabric of space-time around him. The engine did not merely channel energy; it reflected the user's internal chaos outward, turning Tetsuo's fractured psyche into a gravitational anomaly that consumed everything in its path, ultimately leading to the erasure of Neo-Tokyo from existence.

In Their Own Story

The hum was not mechanical but biological, a wet, tearing sound that vibrated through the steel floorplates. Tetsuo stood before the glowing sphere, his skin peeling away like old paint, revealing raw muscle and bone knitting together in impossible geometries. The Vector Field Engine pulsed with a sickly violet light, drinking in his screams and spitting out gravity wells that crushed the concrete pillars of the bunker. He reached out, not to touch the machine, but to become it, his mind expanding until the walls of the facility were just thin paper against the infinite pressure of his own will.

Reader's Guide

The Vector Field Engine Core functions as a resonator for psychic energy, specifically targeting the high-frequency output of Espers. In theory, it was designed to focus this chaotic power into a coherent beam capable of immense destructive force or perhaps even teleportation. In practice, the device lacks safety protocols for untrained minds. When activated by an unstable subject like Tetsuo, it amplifies their emotional volatility, causing reality to warp around them. The core does not control the user; instead, it feeds off their instability, creating a feedback loop where mental distress manifests as physical destruction. While initially intended for military use under strict government supervision, the engine was ultimately 'wielded' only by Tetsuo Shima in an uncontrolled state. His interaction with the device bypassed all containment fields, turning the weapon into a catalyst for his own ascension and the subsequent annihilation of the city.

Did You Know?

• The engine's design was based on the hypothesis that psychic energy could be treated as a tangible, harvestable resource similar to electricity.
• Tetsuo's interaction with the core caused localized gravity failures, allowing him to float and manipulate debris before his final transformation.
• The device served as the physical focal point for Tetsuo's evolution into a god-like entity capable of reshaping matter.
• Despite its military origins, the engine was never successfully deployed in combat against an external enemy; its only true 'target' was Neo-Tokyo itself.
