I'm currently in the middle of watching Naruto Shippuden and I've watched other anime, although vary few. My top 5 favorite male characters are as follows:
1. Deidara tied with Sasori

2. Itachi, I think

3. Neji (sorry Gaara, you're one of my favorites too, but imma move you on down to 6th)

4. Sasuke(he barely made the list, I prefer his abilities over Gaara's but he can be arrogant and cold. However, I understand he wasn't always like that, so I chose to add him on here.)
I created my Reading Lists just to remember which one's I've read, some have mature themes, so I recommend skipping those parts (I briefly skimmed them just to know when it goes back to the plot part).
