All I can say is: Awesome episode! Technically, though, it isn't a new opening. It's just the second verse of the first opening. XP And the new ending was awesome. Can't really say much other than :3 is pretty much Killua with his chocolate. If you look in a Hunter dictionary under :3 you'll see "Killua with chocolate".

So, I reiterate: Awesome episode, awesome new opening (video only- song was already awesome) and awesome new ending (can't wait for a full version of it). Also, it seems appropriate that the Hunter Vocabulary isn't the eye catcher anymore. Instead, we have Hunterpedia as told by the two best kids in the series asfter the ending. Sounds about right.
