The Celestial King.
Facing the Demon Lord in single combat, the Celestial King uttered only one phrase: "I have come to destroy you and put an end to your reign." Lero Epeothus laughed, stepping back to engage in battle.
But before he could make a move, the Celestial King raised his hand.
With a mere gesture, he tore open the fabric of space-time, creating a Realm with its own separate laws of physics and existence. The two warriors entered, leaving behind the devastated battlefield.
The final battle commenced. The moment they charged at each other, the sheer force of their speed, they moved massively faster than the speed of God's light. Their fists collided in midair, shaking the dimension itself.
The Demon Lord snapped his fingers and gravity inverted. The realm twisted, up becoming down, space bending like melted glass. A hundred void spear gathered in the air.
"Let the spears of destruction pierce you"
All the spears in the air came crashing down in a speed that defied casuality. The celestial king sliced once and all the spears shattered. Space rewrote itself around his blade.
"You are light pretending to be will",
Lero snarled
"And you are rot pretending to be purpose"
The celestial king answered
The celestial king thrust his hand into the air. The law of motion froze. Lero countered by calling on the sin of constraints, turning laws into shackles that wrapped around time itself.
The Celestial King unleashed Void Manipulation, bending the very essence of space and time into a single devastating attack. A beam of spatial void energy erupted from his hands, striking the Demon Lord. Lero Epeothus was obliterated.
Or so it seemed. His molecular structure reassembled instantly, restoring his body in a blink. "I am immortal, you fool." Summoning a sword forged from the energy of the dimension itself, he lunged at the Celestial King's throat. But the Celestial King caught the blade with his bare hand. With Energy Manipulation, he reshaped the sword midair and swung it back at its creator. The Demon Lord blocked with his arm—only to have it severed. Yet, within a second, his limb regenerated. They collided.
Each punch both thrown created shockwaves of silence that cracked the realm bit by bit, moments where existence blanked for a fraction of a second.
Jumping back, the demon lord opened a rift, from inside hurling a conceptual anomaly of monsters at the celestial king – Most monsters made of forgotten Gods. The celestial king killed all the monsters and shattered the rift with a swing of his sword tearing both the fabric of fate with it.
Both began to falter.
They fought barehanded, Blow for blow. Soul against soul.
With every blow shattered the parts of the realm, and shook the outer verse.
The demon lord screamed – and activated "ECLIPSE AUTHORITY" merging his sword with a black sun he created with the realm's energy (By using the realm's energy he drains the celestial king's energy) the realm turned pitch black. For a moment the twelve crystals within the outer verse and high outer verse died.
The celestial king could not move.
The demon lord with all his power lunged at the celestial king and stabbed him.
The celestial king fell and knelt. His eyes dimmed.
"You're fading,"
The demon lord whispered, voice broken, triumphant
But the celestial king rose again – and kept on slashing him again and again, but the result was always the same.
"This won't do me any good," he muttered. Casting aside the blade, he clenched his fists, a golden aura radiating from his body
"DIVINE HOLY GOD'S LIGHT."
The energy surrounding him surged, illuminating the entire dimension. The Demon Lord, unaware of what was happening, charged forward. Each punch thrown felt like the impact of a collapsing crystal in the outer verse. But as the battle continued, Lero Epeothus realized something. His regeneration had stopped. Before he could react, the Celestial King delivered a final devastating blow, sending the Demon Lord's head flying from his shoulders. The Realm collapsed, and the Celestial King returned—holding the severed head of his fallen adversary. The Demon War was over.
