The link is in the description of the video at the bottom; copy and paste it into the address bar. I strongly advise you to get an account there since almost all of the good models/stages/motion comes from that site. Look for ”パス” or simply the word "pass" and the password to the download is right there. Copy and paste it into the box and voilá! The download has started.
