In a world scorched by inferno and drenched in crimson, a solitary figure stood atop a pile of defeated demigods and fallen apostles, his blade, a work of art in folded steel, slick with the blood of those who dared to challenge. The divine realm had stripped him of everything – his clan, his love – leaving only unquenched fury. Their greatest error was underestimating the power they had trespassed upon: Makaiyama, the legendary Mount of Devils in Ryukoku's lore, home to the fearsome Heavenly Demon.

From beyond the fabric of space and time, celestial beings watched in disbelief as the Heavenly Demon, relying solely on martial prowess and a menacing aura, defeated three divine beings without the aid of magic. Witnessing their eternal kin fall to the hands of a mortal swordsman, their rage ignited.

Despite the numerous wounds piercing his body, the Heavenly Demon, his crimson eyes ablaze with defiance, planted his obsidian katana, soaked in blood, at the summit of Makaiyama, like a stake through the heavens' core. In the abyss of despair, a metallic whisper echoed:

"[Project God Executioner activated.]"

"[Accept?" the voice queried.

Fueled by vengeance, he vowed to rise, not as a pawn, but as the gods' nemesis."
