For those who need a brush up, Naruto follows none other than a boy named Naruto who is a jinchuriki. A jinchuriki is a human who has a demonic tailed-beast sealed inside of them. Orphaned on the day he was born, Naruto grew up as an outsider due to being possessed (or something like that) by a demon. Along his journey he ended up making friends and saving the world a few times. Even if you've only seen a few episodes of Naruto, you'll know this. But what we have in store for you is only for those who are real Naruto fans. These questions vary from so easy that they'll go over your head, and some that are so hard that you'll have to fight the urge to google them!
So, Naruto Fan Quiz is the best thing to test it.
