Killua moved first. His speed detonated to its limit as he shot forward like a streak of lightning, closing the distance to the Dark Beast in an instant. He aimed straight for its head. Electricity exploded across his body.
"Wrath of the Thunder God: Lightning Blade!"
His strike came down like a cutting arc of pure speed and power. The Dark Beast's face rippled from the impact. But its massive form did not budge. Not even slightly.
Its jaws opened. Darkness gathered. Then — release. A torrent of black energy surged outward, swallowing everything in its path. Killua's lightning vanished into it. The collision erupted into a violent shockwave.
"Killua!"
Gon's voice broke through the chaos. But Killua was already moving. His body flickered through the current, riding his own electricity to escape the collapsing vortex.
"I'm fine!"
He reappeared above the battlefield, eyes sharp.
"Now, Ryker!"
Ryker didn't hesitate. He moved the instant the opening appeared. A flash of lightning carried him forward, cutting through layers of dark energy. The System surged. He adapted mid-flight, drawing in surrounding fragments to reinforce his output.
Then — he saw it. Inside the Dark Beast. Not on the surface. Buried deep within its core mass. A concentrated source. Endless darkness flowing outward from a single point.
"So that's it…"
Ryker's voice dropped.
"The true source."
He raised his blade. All lightning converged. Compressed. Focused.
"Thunder God's Judgment: Break."
The strike fell. A piercing arc of lightning drove straight into the beast's abdomen.
Impact.
The world shook. Space twisted under the force. Then — a sound. A real one. Pain. The Dark Beast roared. Its massive body convulsed. The darkness destabilized. Energy began to leak.
Ryker didn't stop. He pushed forward. Lightning surged again, brighter than before. He raised the blade one final time.
"This ends now."
The strike came down. Direct. Precise. It pierced the core.
"Break."
Detonation.
A massive explosion tore across the Dark Continent. The Dark Beast shattered. Its body fractured like glass, collapsing into fragments of darkness that dissolved into nothingness.
The pressure vanished. The sky cleared. The suffocating presence was gone.
Ryker stood in the air, breathing hard, the Thunder God's Judgment Blade still in his grasp.
Below him — silence. Then — relief.
"Gon. Killua. Biscuit…"
"We did it."
"The Dark Beast is gone."
"The source… has collapsed."
Gon let out a long breath, a grin breaking through.
"It's finally over!"
