Good to see a wall showing the serious side of YnM, especially 'Devil's Trill'. I love that arc. You've chosen appropriate pictures, and demonic Tsuzuki is so darn cool. The purple of the title is a little out of place, though I like the reddened clouds around the bright white moon, a contrast to the red moon which is a symbol of the series. Its a simple wallpaper, but I like it.
