That is the Full Burst of the title—not an explosion, but a sustained, unbearable resonance. And the “Normal...” is the quiet admission that for a Saint, there is no other way to live. Only to burn, and to call that burning ordinary.
In the vanilla narrative, Seiya survives. In the mod’s “Normal” mode, perhaps he doesn’t. Perhaps the final screen is not a credits roll, but a single line of text: “Their Cosmo still echoes in the void. Press any button to feel nothing.”
The mod functions as a digital elegy for the Gold Saints. In the “Normal” mode, when you unlock the ability to play as Saga, Camus, or Shura during the destruction of the Wailing Wall, their “Full Burst” is a one-time use. After activation, their sprite might flicker and fade to gray—a mechanical enactment of their Ikari no Hōkō (Roar of Rage) before petrification. The player is forced to confront that the power to break through the Wall is synonymous with the end of existence.
