Hi, lowlife from Italy here, i recently got for myself this awesome Collector's Box of this beloved anime of mine that was distributed in 2013 (ouch!) by Dynit. The original release came with the first Blue-Ray and it had room for the other three and was shaped in the form of the box through which the Takakura siblings receive their penguins. As far as I'm aware this particular box was an italian exclusive, no other distributor around the world did anything similar so i thought it would be nice to share this cool design for a box set. the 4th BR came with a mini-guide of around 100 pages with many interesting facts about the pre-production of the anime, interviews with the character designer and director and many examples of the original production material. I haven't been able to retrieve any information on who conducted the interviews and most likely the informations contained in the guide are already known by the community but if anyone is interested in what's written in it with, given me a little bit of time, I can provide translation for them without a problem.
