Anything with a run time of less than 20 minutes, and has 3 or more episodes is on this list. Including DVD/TV specials for longer run-time shows. The list is ordered with stand alone shows first. So, if you're looking to buff your anime numbers...
Short comments for all the anime I've watched. A constant work in progress.
I'm only including what I view as Slice of Life anime, aka, kids having fun doing stupid stuff and nobody dies.
Anime that I find has most of it's success from the fact that one or multiple characters are absolutely cutesy. Take list with a grain of salt. Not in order, though first is selected for it's icon.
