If your experience of Swod Art Online is limited to the anime series you probably won't be familiar with the character introduced today by the just another Sword Art Online: Infinity Moment trailer.

Her name is Sinon, and doesn't appear in the anime at all, as Kirito will actually meet her after the events of the series, when he joins the online shooter Gun Gale Online, because all the ladies he had gravitating around him weren't enough.

If you want a glimpse on a character we'll meet in the pretty much inevitable sequel of the anime, you can check her out below.
