Kinda surprised there's no Muramasa section to put these wallpapers in...
Kisuke is one of two characters you get to choose when you start the game, if you've never played the game before (and you should, 'cause it's pretty awesome.) In the end, you'll end up playing both characters, the difference being they start out on different ends of the map and have different story lines. But they get the same katana.
Anyway, enjoy the wallpaper, and go buy/play the game
Oh, and the 1440x900 resolution is better only because I got a new monitor and that's its pixel ratio. Just to let you know. And the wallpaper is written in French only because I know French and like how it reads. That's all.
