"Black Crow, die!"

With a low shout, Saya swung the massive spear, thrusting it toward Mio in an instant with a sharp whistling through the air.

Mio remained calm. He stepped forward and disappeared along with the skeleton giant.

"Not good."

Suddenly—

The sound of air splitting came from behind.

Saya spun around, spear sweeping to counterattack.

However, just as he turned, Mio's figure vanished into thin air again.

Then, Saya sensed Mio reappearing on his right side with Observation Haki, the next blow imminent. But when he tried to turn again, his body lagged behind his thoughts.
