As Dawn extracted Kaido's soul, Chloe at his side continuously used her power to erode his body, gradually demonizing him.
Kaido had failed to notice for two reasons. First, Aokiji had sealed and immobilized his body. Second, Zephyr and the others' attacks further disrupted Kaido's senses.
The pain in his brain and body concealed the abnormality of Chloe's invasion. By then, the demonization had reached his knees, completing roughly a quarter of the transformation.
Every brief stalemate when Dawn extracted Kaido's soul was an opportunity for Chloe to seize and use her power to erode him.
In that instant, Kaido lost control of his body, and his rejection response vanished. Even if the soul extraction failed, it at least caused Kaido's soul and body to fall out of perfect alignment for a moment.
Chloe took advantage of that opening to invade.
As time passed, the demonization had reached Kaido's heart, and more than half the erosion was complete.
Perhaps it was Dawn's mockery, or perhaps the disharmony in his body, but Kaido finally realized that something was wrong.
"Why can't I feel my body?!" Kaido roared, his eyes splitting with fury. "Brats, what the hell are you doing?!"
"Didn't I tell you? We're killing you."
A terrifying smile appeared on Dawn's face. "More than half your body has been demonized by Chloe. Once you're completely demonized, you'll become a weapon that obeys only me."
"Don't even think about it!!"

Chloe's demonic invasion immediately halted, even showing signs of receding and recovering.
"Not a chance!"
Seeing Kaido launch a final counterattack before death, Dawn shouted as the soul fluctuations around him erupted at full force,
