Anime with strong friendship?

I know it may sound weird, But I truly love animes with real and strong friendships in it. Usually in an anime, if you hear your 'friend' badmouthing you, they get gullible and it all goes messy in the end. I love kimi ni todoke because of the strong alliances, I also love special a. On how they act like family and watch out for each other. I don't like the cliche 'one best friend'.. the more the merrier!
