"Here we go, Asuna! Hang on tight! Tilnel, launch!"Having said their
good-byes to the mysterious elven knight Kizmel, Kirito and Asuna set their
sights on the fourth floor of Aincrad. But once they open the door, they find
the way forward blocked by a powerfully flowing river. The updated version of
the fourth floor has been changed into a water world! When they finally arrive
at the floor's town, they're greeted by chalk-white streets and countless
gondolas of all sizes. To navigate this place, Kirito and Asuna will need their
own gondola–but getting one will involve confronting an eight-meter-tall beast
of flame: Magnaterium…And that's only the beginning of the difficulties the
fourth floor of Aincrad has in store!
Sword Art Online: Progressive, a new version of the Sword Art Online tale
