No matter what age it is, bullying will never disappear. The overweight, middle school student, Haruyuki, was one such kid. The only time he could relax completely, was when he would play a squash game on the local network the school had set up. He loved playing this simple game as he can forget painful times while immersed in it.

It was fall. He was passing his time like this until one day, he had an encounter with the school's most beautiful, refined girl, "Snow Black," which changed his life abruptly. Introduced to the software she transmitted, Haruyuki learned about "Accel World." A program that enhances one's mind capabilities, with certain side-effects.

It was the moment the guy on the lowest rung at school became "Burst Linker," protecting the Princess as her knight.

Having won a photon sword in a mini game, Yui decided that it would be the perfect gift for Kirito. However, convinced that a present is more impactful when it's delivered as a surprise, Yui enlisted the help of Asuna and the other girls. The girls would face Kirito in battle during a new GGO event and create an opportunity for the perfect surprise: using slime guns to blind him during the fight, thus allowing Yui to present her gift to the unsuspecting Kirito just as he regains his vision. However, Yui did not foresee one thing: that her surprise gift will have to compete in impactfulness with Kirito's mastery at getting himself into all kinds of ecchi situations...
