This was a fairly close battle between two extremely fast sword fighters. Erza has many different armors, which grant her different abilities while overwhelming opponents with sheer power and speed is Kirito’s bread and butter. Kirito’s lack of long range options is what really holds him back here as Erza should be ale to keep up with his speed. What Kirito needs is some kind of power up and I wouldn’t be surprised if he gets it someday. As of now, Erza has the edge. Erza wins.
