What is your favorite non main stream anime?

My favorite has to be either Initial D or Air Gear.

Death note. You could say that it is a little bit mainstream though.

hmm Yes I have like many favorite anime,for example seven death sentences sins,there is no game there is no life

Knights & Magic, The Irregular at Magic Highschool, Infinite Stratos, I could go on and on lol

i love hanasaku iroha, is not my number one but its an anime i really enjoyed watching, its really beautiful

My favorite non stream anime is probably "Another".
