Has there been an 아니메 in which 당신 liked the entire cast?

Durarara is one for me too and another one would been Fairy Tail! ♥♥♥

두라라라!! for me too, as well as Gatchaman Crowds (cannot say the same for Insight) and Binan Koukou Chikyuu Bouei-bu LOVE!

Detective Conan :3

Durarara is one for me too! Ouran High School Host Club,K-ON, and 헤타리아 come to my mind here as well!

Durarara, Host Club and Black Cat

Ouran

PriPara. All the characters are wonderful and the show makes me wish that my 프렌즈 IRL were like this.

Yep...AnoHana.

They are just real awesome that I can't help but 사랑 all of them! Well...at some point I got annoyed at Yukiatsu and Anaru but due to some stuff (Anaru showing her somewhat nerdy side and Yukiatsu in the OVA) I eventually loved them all the same! :D

Aside from Slam Dunk, I do really 사랑 all the characters in GINTAMA, even the villains are likable XD

I like most of the characters from Attack on Titan
