Shigofumi
And to add to the anguish/awesome, I present you the sequence of sorrow. If youse is a fan you can tell where each bit is from, and why it's so awesome

I really loved this show. Awesome twists in just the first episode and really good at making you second guess the characters. Really really awesome show and I'd love to see more.Ka-CHING! Awesome character design and premise, shocking twists, and the promise of well developed characters in each episode, all of whom will die horrible deaths. Yay! Oh, and I am very much looking forward to seeing the postalwoman go postal.
My one fear is that, at some point, the messenger will go on some "Ah'm gonna fight da SYSTEM!" thing and goes to war against the postal service or something.
As I said earlier, it's Higurashi, except you don't have to wait two years for an explanation, and there are no horned phantom people whatsoever.
Plus, that girl looked like Chloe. Whee!I really enjoyed watching this one. There were such good twists, and I'm really curious to find out more about the girl that delivers the letters. She seems to have a bit of back story regarding her gun. Definitely love to see more of this one.Shigofumi has the best first two episodes I've seen since Code Geass. I was kind of bored for the first fifteen minutes of episode one, but then the plot twist hit me like a ton of bricks (so did Fumika whipping out a giant gun). I can only wonder what other unsavory situations characters will get into regarding the letters. The letters themselves are a very intriguing concept, and they're suprisingly believable as a method of revenge. I like how the letters aren't always read to the audience, too. I'd love to watch more of this show.
