Out of the original, CLANNAD.
Naruto would've been my pick but I only read the manga

Out of these Naruto and Black Butler are my fav.

Death Note has been my favorite for a long time now.
It is followed closely by Code Geass, Another, Air, Kuroshitsuji, Sola, Neon Genesis Evangelion, CLANNAD, and Infinite Stratos.

We can't keep doing these questions. -.-

Clannad, Angel Beats!, Dragonball Z, and Air. I would've also added Shingeki no Kyojin..

clannad, bleach, angel beats, another, black cat lol i really wanna watch infinite stratos lol

i love this anime. my other favorite anime are: Digimon, Beyblade, Yu-Gi-Oh, Bakugan, and Detective Conan.

I like a lot of these quite a bit honestly.
