The night of the ritual, the forest was alive with a terrifying energy. The Void Kids and the Supreme God had spent hours carving massive, glowing symbols into the earth, forming a summoning circle that spanned the entire clearing. This wasn't just magic; it was a "Summoning Jutsu" of a meta-cosmic scale, designed to pull entities from the deepest layers of the unwritten void. The air tasted of ash, and the sound of distant, inhuman screaming echoed through the trees as the barriers between worlds were lowered.
The Supreme God began the chant, his voice echoing with a power that made the very ground beneath them vibrate. He called out names that hadn't been spoken since the first dawn—demons of shadow, of rot, of madness, and of blood. These were the "Terrible Demons" of every mythology, beings so destructive that they had been erased from the official script of the multiverse. One by one, they answered. Portals of jagged darkness ripped open around the circle, and the horrors began to crawl through.
The sky turned a bruised, bloody red as the demons manifested. They weren't just monsters; they were personifications of every fear ever felt by a living soul. The Earth cracked under their weight, and the Reality Limits hummed at a pitch that caused the heroes' ears to bleed. It was a gathering of nightmares, a literal hell on earth. The army of resistance watched in stunned silence, realizing that the "Solution" was just as terrifying as the problem they were trying to solve.
Then Lucifer stepped into the center of the circle. He didn't look back at his friends or his allies. He raised his hands, and a forbidden fusion jutsu began to take hold. The summoned demons didn't just stand there; they began to dissolve into streaks of black and crimson energy, all of them being drawn into a single, central point. The air became a vacuum as the energy condensed, twisting and folding into a new, colossal form that towered over the trees.
The result was the Terrible Demon, an entity of such overwhelming power that its mere existence caused the forest around it to turn to glass. Lucifer did not simply merge with it; he projected his consciousness into it, taking control of its vast, chaotic mind. He became the pilot of the apocalypse, providing a human-like will to a body of pure destruction. This was the only way to ensure the demon wouldn't simply turn and consume the multiverse itself before reaching Erif.
The demon opened its eyes—six glowing orbs of violet fire—and the world shook. The army of gods, heroes, clones, and Void Kids fell in behind it. They were a motley crew of the broken and the recreated, led by a monster of their own making. The Supreme God stood at the front, his face grim. "The final battle begins," he declared. They began the march out of the forest, heading toward the horizon where Erif × Daniel waited. The war for existence had finally moved into its final act.
