The initial knight who just completed the sword swing on
Kirito's right shook violently.

Kirito wasn't merely sprawled over. His two legs had clutched
around the knight's unnoticed, pulling the knight down atop
himself.

The second knight could not stop the slash in motion and the
great sword's blade buried itself deeply into his ally's back. The
knight who recovered his sword while showing signs of shock
was then assaulted by a black flash reaching from below.

Kirito, his lunge accurately stabbing through the knight's two
arms as he got up, turned towards the third knight who appeared
to be charging forward in disorder and shoved the second away
with all the force he had. As expected, the third couldn't hack at
him along with an ally and halted the slash.
