Title: 'Your back is dingy.' ('Naki no Ryuu' reference.) I think some of you have already seen this drawing before, but the one which was uploaded on the Pixiv formerly was reproduced without permission by someone else, and the original one was posted by me on the Mixi application "Kioku-Sketch". Since I did not have enough time, I uploaded without having completed it, so after that I have been modifying the image little by little which I had saved locally, but I have never imagined that meanwhile somebody else made it his/her drawing.... Therefore, since I have completed my finished version, I am going to upload it again (well, for me, this is the first time to upload, so it is not "again" lol) 'Ryyyiisoo (All green)' is an indispensable yaku for Miku, isn't it?
Mixi application is something similar to Facebook application. "記憶スケッチ (Kioku / memory -Sketch)" is an oekaki board application where you can post your drawings made with 2D drawing applet. This application was made aiming at "enjoying unskilled drawings made with a vague memory".
