Description
Lay Gransdori, alternatively spelled Lay Glanzudlii, is a white-haired demon with pale blue eyes, frequently clad in the black-and-red long-coat uniform of pureblood students at the Demon King Academy. Renowned as the "Demon Swordmaster" and "Saint of Magic Sword Forging," he combines peerless swordsmanship with a tranquil, unassuming disposition, defying expectations of his royal heritage through humility. His egalitarian principles drive him to interact with all beings impartially, shunning political entanglements like the Royalists or Unitarians while maintaining an approachable demeanor.

Born into the prestigious Yvesta magic lineage, Lay was exiled after his magic source, already intertwined with Syrica—a remnant of his past life as the hero Kanon—prevented him from inheriting family spells. Abandoned at five, he was adopted by Sheila, a half-demon, half-spirit woman whose subsequent spirit disease and hospitalization became a vulnerability exploited by the Royalists to coerce him. A prodigy, he mastered swordsmanship rapidly, defeating his dojo instructor within three days and dominating tournaments before enrolling at the Demon King Academy.

As Kanon’s reincarnation, the ancient hero who clashed with Demon King Anos Voldigoad two millennia prior, Lay wields seven soul fragments called sources, granting regenerative resilience. True destruction requires annihilating all seven, each loss causing agonizing pain. Using source magic, he concealed his identity by dispersing six sources among the Seven Elder Demon Emperors, evading even Anos’s detection.

Transcending martial norms, Lay wields holy, demonic, and spirit blades simultaneously—a rarity among demons—employing techniques like "Heavenly Fang Sever" to manipulate fate. His arsenal includes Initiio, a magic-nullifying sword, and Evansmana, a holy blade that severs destiny. Adapting mid-combat, he absorbs opponents’ techniques, refining his prowess in real time.

Orchestrating a millennia-spanning scheme to halt human-demon strife, Lay posed as the fabricated Demon King Avos Dilhevia, intending to absorb collective hatred and perish as a sacrificial peace emblem. This ruse inadvertently birthed a real Avos—a spirit formed from the legend’s lore, later revealed as the spiritual essence of Misa Ilioroagu, his lover. His dynamic with Anos shifts from adversarial rivalry to mutual respect, their clashes catalyzing Lay’s growth.

Key relationships include unwavering loyalty to Sheila, his adoptive mother, and a romantic bond with Misa. Interactions with Anos reflect their entwined histories as former foes turned allies, united by Lay’s drive to safeguard the peace Anos founded. His morally complex choices—particularly the Avos deception and self-sacrificial gambits—spiral into unintended repercussions, testing his resolve.

Navigating dual identities as Kanon and a demon, Lay reconciles past and present, thwarting Royalist manipulation, rescuing Sheila, and confronting adversaries like Melheis Boran. These trials highlight his strategic acumen, resilience, and relentless pursuit to dismantle cycles of vengeance, even at profound personal cost.
