Great Red's Domain

In Their Own Story

The air shimmered with a crimson hue as Issei stepped forward, the ground beneath him feeling less like solid earth and more like flowing energy. Great Red loomed in the distance, his massive form casting a shadow that seemed to swallow the light of the void. Every breath felt heavier here, the gravity pressing down not just on muscles, but on the very soul.

Reader's Guide

This power originates directly from Great Red himself rather than being an external artifact like a typical Sacred Gear. It functions as a reality-warping field where the Dragon God dictates all environmental rules. Known abilities include manipulating physical constants such as gravity and time to simulate extreme combat scenarios for training purposes. Limitations are strict; only those granted entry by Great Red can exist within this space safely, otherwise the pressure would crush them instantly. There is no evolution stage because it is a static manifestation of his current power level. Characters like Issei Hyoudou have utilized this domain to refine their Boosted Gear usage under conditions that force adaptation beyond normal limits. Combat applications are defensive and educational rather than offensive for outsiders, as the domain itself protects Great Red from external threats while allowing him to test potential allies or rivals. It remains one of the few places where even high-tier Dragon Kings cannot easily interfere without consent.
