Kazuto jumped off the ground to make sure he didn't give his opponent another chance to attack him. But the moment his eyes did not see the man because there were shards of rock blocking his view, Zen had disappeared from his sight again.
Kazuto activated the magic shield around his body and let gravity pull his body down while glancing around to find his opponent's figure.
Unfortunately, he was utterly unaware of Zen's existence, who was right behind him and his hand lifted and moved towards Kazuto's head.
By the time his instincts warned him of danger from behind, it was too late. Kazuto's body was pushed downwards quickly and violently, causing his face to hit the ground while the ground beneath them crumbled.
Zen landed his feet on Kazuto's back frame to restrain the black knight's movement.
