IMO this is the best version of Sorairo Days, but not many people even knows it exists. Yes, its an official version.
From Nakagawa Shoko's 2008 album Magic Time. I do not own anything. The rights of the song and pictures goes to their respective owners. Since this song is difficult out of the ass to find nowadays, I thought I'd provide a DL link. I'll take down the link (and video) if Gainax, Sony, or Nakagawa Shoko complains. You know, legal stuff to hopefully cover my buns.
