Since a lot of people keep commenting on my icons, I figured I should post here: my absolute favorite anime/manga is Mushi-shi. The guy in my icon is Ginko, who is arguably both the main character and the character who matters least in the story. It's a very interesting anime, very quiet and low-key, and is mostly about normal people whose lives are interrupted by a bit of the strange; something a little unsettling, a little creepy, or sometimes even a little wonderful spilling into their otherwise mundane and ordinary world.
If you want to watch it, season one is on Youtube, in both English and Japanese; it's even put up by Funimation themselves, so you don't need to worry about watching it illegally or that it will be taken down! Season two is on both Crunchyroll and Netflix, though that one is just in Japanese, alas (I like Ginko's English voice a lot, heh).
Oh and if you're wondering to watch the anime or read the manga, go for the anime. They're honestly exactly the same, though the order of the episodes is mixed up (though with a canon like Mushi-shi, that doesn't matter at all I promise. It's very episodic in a way that doesn't make you frustrated or bored) the anime has the most gorgeous scenery you'll ever see and a musical score that will make you weep. And people speak very soothingly and quietly, I could just fall asleep to it sometimes XD
