Haruhi x K-On! = instant total epic win!
This picture is made of pure epic win! Totally cool!!!! Haruhi and K-On! in one picture with the characters swapping costume each other. Mio in Haruhi’s gekisou costume, Haruhi in Mio’s gothic costume, and Mugi in Yuki’s gekisou costume, and the rest of them are total instant win.
Too bad there’s no wallpaper resolution of this picture. >.<
