Miku-4 (mikuyon)

Miku-4, pronounced mikuyon, is a doujin 4-panel comic by Nagimiso that took the net by storm some time back. This comic has very few words but tells a pretty long story of Hatsune Miku's (the vocaloid character) coming of age.

I got the tankoban bound edition at BookOff! this week. This version varies slightly from the web edition but the majority is the same. (I recommend getting this version if you can because the art is much larger and nicer.)

You can read it here (some Japanese).
