You could try looking on Amazon Prime Video. They sometimes have English-dubbed versions of anime shows like Clannad After Story. Another option is to search on specialized anime streaming websites, but be careful as some might not be legal or have good quality.
Definitely not. Fanfiction is a product of our modern - day creativity and the ability to share ideas on the Internet. In the Naruto world, they don't have the infrastructure or the cultural phenomenon of fan - based fictional writing. Naruto is too busy with things like protecting the village, training, and dealing with real - life threats to even think about something like fanfiction.
I'm not sure. It's often not legal to watch things for free without proper authorization. You might try some legal streaming platforms that offer free trials.
One reason could be curiosity. Naruto might be curious to see how fans imagine different scenarios in the Naruto Shippuden universe. Maybe he wants to see how others view his friends and his own adventures.
You might have luck on platforms such as KissManga or Manganelo to read Naruto Shippuden manga online. But keep in mind that the legality and availability can vary, and it's always best to support official and authorized sources.
