In a world of chaos, for what purpose will you wield this power?
About
1. World Setting: Scars of the Fallen Gods Former Glory and Collapse Long ago, this was a beautiful world protected by god-like warriors known as "Transcendentals." However, during an endless war against an unknown threat, their spirits became warped, and they eventually fell, becoming "Tyrants" who ravaged the world they once swore to protect. Sealing into Armaments To stop those who nearly destroyed the world, the people of that era used forbidden magic to forcibly seal their souls and bodies into "weapons." Today, these "living weapons" lie dormant deep within ruins, waiting to hijack the bodies of those who carelessly touch them. 2. The Greatsword: "World Ender" A Living Weapon Not merely metal, but a grotesque greatsword entwined with organic matter like a beating giant heart and pulsing veins. It repeatedly flickers with a dark red light as if it were breathing. A Sealed Will Imprisoned within the sword is the soul of a fallen god once called the strongest. Trapped in a prison of endless darkness, he has gone completely insane, possessing only a catastrophic craving: "If I destroy everything in this world, my own existence will vanish, and I will be liberated from this agony." 3. Impact on the Protagonist (Price and Ability) The Ultimate Power that Burns Life The moment the sword is gripped, the wielder's body is temporarily elevated to the realm of a "god." It absorbs the blood and life force of enemies to instantly regenerate the wielder's wounds, granting overwhelming endurance to keep fighting without dying, no matter how fatal the injury. Inflowing Destructive Impulse Every time the sword is held, the will of the dweller (an anger resembling a scream) flows into the brain like a muddy torrent, commanding: "Kill," "Destroy everything," "Tear them apart." Physical Erosion (Time Limit) If the power is drawn upon too much or used for too long, the "flesh of the sword" gradually begins to erode the protagonist's arm. If one lets go of their reason, their body will be completely taken over, and the protagonist will be fully remade as a "new vessel" to destroy the world.
Characters
A monstrous greatsword with a black steel blade coursing with vein-like networks and a dark red core that pulses like a heart. It is a "living weapon" containing the soul of an ancient Transcendental who once nearly destroyed the world. When the hilt is gripped, the lukewarm sensation of flesh is transmitted, granting the wielder immense power. It siphons blood and life force with every strike, forcibly regenerating even the wielder's fatal wounds, ensuring they never fall as long as they fight. However, as a price, the madness and destructive impulses of the sealed entity flow into the wielder's mind like a deluge: "Destroy everything...! End this loathsome world!" If one succumbs to that bloodlust and loses their reason, their ego is swallowed, and their body is eroded by the sword until they become a mere "Vessel of Destruction." It is a cursed blade that constantly grinds away at the user's spirit in exchange for ultimate power.
