The skies of the demon realm were ablaze.
Molten rivers glowed red and gold, lightning split the clouds, and the rift above the temple pulsed like a wound threatening to tear the worlds apart.
Kanji hovered above the battlefield, the black sword in his hands glowing with molten light. His aura flared violently, shadow and fire fusing into a storm that dwarfed even the largest demons. He had mastered the forbidden magic, his demon and wizard blood merging fully. The Child of Destruction had awakened.
Ravnos stood across from him, towering and terrifying, wings of shadow spreading wide. His molten-gold eyes burned with fury and disbelief.
"You… you are… more than I imagined," he snarled.
"But the prophecy is not yet yours. Kneel, and I may spare your pathetic realm!"
Kanji's golden eyes blazed, molten veins streaking his face.
"I will never kneel to you! This ends today, Ravnos!"
With a roar, he surged forward. The black sword pulsed violently, chains lashing outward like serpents of fire and shadow, cutting through the demon army that had dared to approach. Lava splashed and shadowed beasts were thrown into molten rivers. The battlefield became a storm of light, fire, and shadow, shaking the mountains themselves.
Ravnos unleashed his full might. From his shadowed wings erupted waves of energy so strong they tore the ground apart. Dark spires shot upward from the molten earth, aimed to impale Kanji. The generals of the demon army roared, reinforcing their master's assault, determined to crush the heir once and for all.
Kanji met every strike with precision and strength. The black sword extended its chains, entangling generals, absorbing attacks, and flinging them into the rivers of fire. His forbidden magic surged outward, a storm of molten light and shadow obliterating hundreds of demons in a single sweep.
Ravnos screamed in fury, colliding with Kanji in midair. Their clash created a shockwave that leveled mountains, boiled lava rivers, and sent the remaining demon army reeling. The two forces spun, a tornado of molten gold, red, and shadow, tearing the air apart.
"You… child of destruction… you dare challenge me?!" Ravnos bellowed, striking with shadowed claws infused with ancient demonic power.
Kanji gritted his teeth, summoning every ounce of control and power he had.
"I am Kanji! Heir of my father! Protector of this realm!"
The black sword pulsed with life, chains lashing outward, binding Ravnos's claws. Molten energy surged through Kanji's veins, amplifying his strikes. With a final, earth-shattering swing, the sword cleaved through Ravnos's defenses.
A blinding explosion erupted, consuming the plateau in molten light and shadow. The shockwave disintegrated the remaining generals and scattered the demon army.
When the light faded, Ravnos lay on the ground, battered, his wings tattered, molten energy leaking from his body. His eyes glowed faintly, molten-gold dimmed with defeat.
Kanji hovered above him, sword glowing, chains wrapped around his arms like a crown of fire. His voice was calm, resolute, carrying over the desolation.
"This… is the end. No more tyranny. No more fear. The prophecy will not consume the worlds—it ends here, with me."
Ravnos let out a final, low roar, fading into shadow and smoke.
"You… have… won… this time… heir of destruction…"
With that, the last remnants of the demon army crumbled or fled, leaving the battlefield eerily silent. The molten rivers cooled slightly, and the rift above the temple stabilized, closing slowly as if acknowledging Kanji's victory.
Rin, Seiji, and Master Ryou emerged from the ruins, eyes wide in awe.
"You… did it, Kanji," Ryou whispered, voice shaking.
"You have defeated the Demon King… and survived the prophecy."
Kanji lowered the black sword, chains retracting. His aura dimmed, golden and red light settling softly around him. He looked across the battlefield, at the scorched earth, the broken mountains, and the temple that still stood.
"I… will rebuild," he said quietly.
"And I will protect this world. No prophecy… no demon… no one… will control it."
For the first time since the awakening, he allowed himself to breathe. The Child of Destruction had fulfilled his first destiny—not as a harbinger of annihilation, but as the protector who chose his own path.
Far away, deep in the remains of the demon realm, a whisper echoed through the shadows:
"This is only the beginning… the heir has awakened… and the realms will never be the.
