This is for number 82, Sorrow, of the 100 Wallpaper Challenge.
When I think of sorrow in anime, I think of Elfen Lied. I should; I did bawl for the final episode and a half after all. Out of all the anime I've seen, I think this anime just did the best at conveying the emotion of sadness. No other anime has quite reached what this anime did. And, of course, the song Lilium doesn't help, either.
