The Azure King's Rage

The scream was four times more powerful than the ones it released before. Its scream was so high-pitched that Elliot thought that his eardrums would explode.

He shifted the sword in his hand and pierced the sword at the halved Azure Core. He continued piercing his blade until the core was shattered, making the Azure King drop Excalibur from its hands.

"Elliot," Aquarius called out. "It's gonna rage."

Elliot gulped and rushed to where Aquarius was. They were approaching the part where the bosses would go into a berserk state and destroy everything in their path, the rage mode. 

It felt like there was an ominous feeling as the Excalibur rolled from the roof and down to the ground. The Azure King grew to its original size, making the roof under it collapse from the extreme weight.

Elliot and his friends managed to secure themselves out of the roof. They landed on the ground as they watched the Palace slowly tremble.
