I only catch bits n pieces while my husband watches it, but the main character is this boy Naruto who, at birth, was used in a ritual to seal away a powerful fox demon Kyuubi (that first clip he's fighting to keep it controlled inside himself)...when he gets really mad it's aura is partially released and he gets the tails...Sora's one of the friends he usually fights with, looks like the demon somehow took him over for that episode...the storyline is really long and convoluted and full of filler episodes (part of why I don't pay a lot of attention), but he and his friends are all ninjas in training, trying to protect their hometown and then later trying to rescue a friend that turned evil or something...I lost track about 50 episodes ago, but if you're really curious I could always ask my husband to post a more detailed synopsis![]()
