Synopsis

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.

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…
