That's the part I enjoyed watching the most :/, along with Sakura going agro on him. That's always fun, probably not for Naruto though :p. My sister says there's about 21 or 22 episodes and she said it goes into Alpha Online or something at some point :/. Is that true or have I got really bad hearing ;_;?
But yes, I'm going to watch Sword Art on Friday or Saturday all day long >:D. Who cares about bad eyes, I've got an anime to watch :D.
