What anime should I watch next?

Angel Beats is only 13 episodes, if I remember correctly! And it's really good. X3

Oh, and you should watch Kuroshitsuji 2...even if you don't like subs, it's definitely worth it!

Edit: Oh, and Baka and Test! It's only 13 episodes, and it's hilarious.

I would say:
Ao No Exorcist
Shakugan no Shana
D.Gray-Man
K-ON
Durarara
Kaichou wa Maid-sama

On the photo is Lavi from D.Gray-Man

i think ToraDora or Dararara

Pretear- 13 episodes
Mermaid Melody Pichi Pichi Pitch- no dubbed, about seventy episodes, including season 2
Ojamajo DoReMi- lots of episodes, but there are about forty in season one
Tokyo Mew Mew- 52 episodes
Full Moon wo Sagashite- 51 episodes
Black Rock Shooter- I forgot how many, but it's short-ish
Lucky Star- 24 episodes
The Melancholy of Haruhi Suzumiya- about 26 episodes
Nyoron~! Tsuruya-chan- about 20 episodes
The Melancholy of Haruhi-chan Suzumiya- about 20 episodes, watch after watching the original Haruhi Suzumiya, both seasons
To-Love Ru(ECCHI)- Forget how many episode, semi-long
Club-to-Death Angel Dokuro-chan(extremely violent, ambiguous plot, bloody)- Once again, I forget how many episodes, but I think it's short
Ranma1/2(FREAKING LONG!)- around one hundred episodes, but it's still worth watching. The dub is fantastic, too!
Hope I helped!<3
