Animes like Narabi no Ou, Pandora Hearts, and Black Butler?

The thing that makes these animes so amazing is being able to see the bond between the characters; also the 2 main male characters bond. Also the characters in all 3 of these are similar to each other in looks and actions, just different colors since they are done by the same studio. I was wondering if Square Enix has created any other animes like these 3?
