PS: The author of the video permits the reprint of this animation as long as people who are sharing his works gives full credit in their video description and don't monetize his work on Youtube. I have asked this in his "ask.fm" account and here is his answer in Japanese but he is basically talking about these two important issues in his answer which is "don't monetize his works on Youtube" and "give full credit the animation he made in the video description": http://i.imgur.com/NFx6BBp.jpg
