In terms of unpopular anime, it's definitely going to be Watamote/Watashi ga Motenai no wa Dou Kangaetemo Omaera ga Warui!
It's quite an unpopular school anime about a girl who thought she was going to be popular in High school, but she isn't. It really deserves more fans/viewers because it's awesome. C:
