"Wah!"
Sirius flew through the air, already transformed into his werewolf form.
"Too weak, kid."
Teacher Kaido, who had sent Sirius flying with a single blow, sneered disdainfully. "If you can't block it, can't you at least try dodging?"
Sirius scrambled up from the ground, only to see Yamato charging forward with her spiked club dragging behind her.
An invisible ripple coiled around the spiked club in her hand.
This was Armament Haki coating, the most basic of the four ways to use Armament Haki.
Sirius knew that coating, hardening, emission, and Internal Destruction were not strictly ranked above or below one another. They were simply different methods of use.
Although the power they could unleash varied enormously, the difference lay in technique—like using the same gunpowder to make firecrackers or bombs.
The true distinction in Armament Haki came from its quality and quantity. It was not as though Internal Destruction Armament Haki was necessarily stronger than hardening.
Theoretically, even Sirius, who had only just awakened his Armament Haki, had the potential to master Internal Destruction.
Yamato, who had rushed in, was soon sent flying back as well.
The Armament Haki coating her spiked club was completely useless against Teacher Kaido's iron club. It was scattered in an instant, and her whole body was hurled backward.

Even as he scolded them, Teacher Kaido's massive body flashed forward, and the spiked club in his hand swung straight at Sirius.
Sirius focused his mind. He coated his greatsword
