I'm looking for manga with a pair/group of siblings as main characters with equal (or close to equal) importance/focus in the story. It can be a story about them as a group, or with separate arcs focusing on each of them in turn. Examples would be Fullmetal Alchemist, Ao no Exorcist and Donten ni Warau.

I'm mostly interested in adventure shounen right now, but feel free to suggest other genres as well. Slice of life would be nice too. Thanks in advance!
