Cursed Sword

Lore & Background

Lostvayne's power lies in its ability to multiply the user's strength and generate clones, rather than draining life force or consuming souls. Meliodas wields it as a Sacred Treasure, and it does not possess a parasitic will or corrupt its wielder. The sword was not forged by the Demon King, but obtained by Meliodas later in his journey.

In Their Own Story

The air in the ruined temple grew heavy, smelling of ozone and old blood. Meliodas gripped the hilt, feeling the familiar, icy chill seep up his arm like liquid poison. The blade hummed with a low growl, eager to tear through the barrier protecting the dungeon. 'Not today,' he whispered, tightening his grip as shadows danced along the steel edge. For a moment, his eyes flashed crimson, and the ground beneath him cracked under the weight of the sword's dark aura. He forced the darkness back, knowing that one slip would cost him everything he had fought to protect.

Reader's Guide

The Cursed Sword operates by drawing upon the user's life force and spiritual energy rather than external mana sources. Its primary mechanic is soul absorption; when it strikes an opponent, it does not just inflict physical damage but begins to erode their very existence, eventually turning them into a hollow vessel for the sword's will. Visually, the weapon radiates a dark, violet-black aura that distorts the surrounding light and casts unnatural shadows. When fully activated by a Demon King or a powerful user like Meliodas, the blade can extend its reach or manifest tendrils of darkness to ensnare enemies. However, this power comes at a steep cost: prolonged use accelerates the corruption of the wielder's heart. The only known users who have mastered it are the Demon King himself and Meliodas in his full demonic form. Even then, control is tenuous. The sword acts as a double-edged blade; while it grants the ability to cut through magical barriers and divine protections, it constantly whispers to the user's darkest impulses, threatening to overwrite their personality with pure malice.
