Story? There's not much of a story. Though they do connect with each other slightly, each episode can be watched out of order, and it wouldn't take too long to catch on with what's going on. Seeing as it's a slice of life though, I wouldn't take any regards to a story rating.
The art worked well for it's genre. The little round faces just made everything all the funnier, while the girls never failed to put on an expression that would send me literally 'LOL'ing at my computer screen.
Sounds? Well, it's catchy. I love the voice actors, if it counts for any. The OP songs are incredibly cute and catchy -- you wouldn't expect to watch what you're going to watch from watching the OP.
The characters are your stereotypical 'Tsundere', 'Airhead', and 'Silent' type girls. ...While the males are strung about perverse characteristics (+the one popular boy).
All this being said, Mitsudomoe is definitely high up on the enjoyment level. Whenever I'm in need for a laugh, Mitsudomoe is there for me. :')
