The gods had taken everything: his clan, his love, leaving him with nothing but wrath. They had made one critical mistake, however, they had crossed into Makaiyama (魔界山), the sacred mountain of Ryukoku’s most feared legend: the Heavenly Demon.Beyond the veil of space and time, celestial beings gazed in shock. “Impossible…” one god whispered, watching as the Heavenly Demon, armed with nothing but raw skill and a dark aura, felled three divine kin. Rage flared across their ranks as they saw their immortal kin fall to mere mortal swordsmanship, untainted by magic.Even as the Heavenly Demon staggered, weapons lodged deep into his body, he fixed his gaze forward, crimson eyes blazing with defiance. His obsidian katana, blood-soaked, pierced the peak of Makaiyama like a stake driven into the heart of heaven itself. His voice echoed in the darkness between life and death, and there, in the chasm of despair, a metallic whisper resonated:“[Project God Executioner has been activated.]”“[Accept?]” the voice asked.With a heart ablaze, he swore vengeance. He would rise, not as a puppet, but as the gods' executioner.
