Naruto Kai is a fan project dedicated to removing filler, padding and any other executive-minded nonsense that made the Naruto animated series the mess that it is. Each episode roughly corresponds to each volume of the comic, running for about 1 and a half to 2 hours. This is a result of the hard work of numerous madlads, (notably including u/Thekaiguy).
I have not contributed to the Kai Project in any way possible. I am just a big fan who felt a website might help organizing this. I have made this website based on this reddit post.
If you face any issues with the website, or wish to request a feature, feel free to start a thread at the gitlab repo, or drop a mail.
Or if you have questions regarding the Kai project, drop a post at r/Naruto).
