Marin is definitely my fave (I was laughing so hard watching the Q/A stuff and seeing how little she seemed to care about it all), but Okamari is right up there too, largely thanks to her blog (thanks again, Estrea!). She is just so goofy and endearing, and I love how she makes little asides to herself in her entries.
But like I said, I like them all. Give us a real album soon, UF!
