Okay, well we are in the third volume of Naruto. In this one Naruto and his team have to train their chakra by climbing trees, WITHOUT HANDS!Meanwhile the evil Zabuza is regaining his strenghth to prepare for his second battle against Kakashi. Soon they are in battle a few days later. Haku is a boy (who looks like a girl) who works for Zabuza. He traps Sasuke in a strange ice mirror technique. Naruto eventually shows up and taps himself with Sasuke. Soon Sasuke discovers the technique he is using, but he is stuck protecting Naruto (WEAKLING!) Haku ends up attacking Sasuke and he uses some weird technique and kills Sasuke. Naruto goes a little crazy.
Well, that's all I can tell you until next time. Buy the book to find out all of the details. Or you can wait until next time to read about volume #4.
