It’s a thing. I forgot about it but it’s nothing rare. They sure recycled the cover well.

The thing on the left is “dekajake” (big jacket?). I haven’t taken out the plastic wrap but it sure looks like a color printed paper of the cover image enlarged. It’s almost shikishi-sized just a bit short.

The B3 poster is reversible with the other side being the photo of yanaginagi herself.

I’ll need to rip the CD sometime. I suspect I haven’t even opened the CDs for S2 theme songs so I’ll do that as well.
