The game follows a "Branching Plot" structure common in visual novels, where player choices dictate the outcome.
The legend of the Gensei Kenki Sacred Arch concludes with its self-destruction. One morning, during a solar eclipse—when the "manifested origin" of the sun is momentarily hidden—the Arch is said to have simply hummed one final, perfect note, then shattered into geometric dust. The dust did not blow away; it rose vertically into the sky and vanished, as if the Arch had finally succeeded in forgetting itself.
To fully appreciate the weight of the "Gensei Kenki Sacred Arch," we must first break down the Japanese terminology likely underpinning the concept. The phrase appears to be a compound of three distinct ideas, each contributing to the weapon's identity.
