one piece: gene extraction and fusion system

"Come on."

Feeling the terrifying slash from the Golden Lion, Mio was not afraid at all. Instead, he was thrilled, his blood boiling with excitement as he shouted, "Demon God!"

Buzz—

A terrifying demonic power burst forth in an instant. That dark energy coiled around the massive skeletal giant behind Mio like a web, forming a hardened scarlet armor. In the next moment, it was entirely coated with Armament Haki.

Then, the power of the dragon awakened.

Blazing flames erupted, spiraling around the armored giant. Fire gathered on its fists, merging seamlessly with the crimson demon fire that burned like a living creature.

Without hesitation, Mio launched a punch.

A violent, overwhelming punch—charging forward to meet the incoming slash.

RUMBLE—

An earth-shaking explosion sounded as the two titanic forces collided.

A massive wave of momentum erupted in the sky, expanding in every direction.
