Here are the two different DVD covers, each with a different "making of" segment.
Former Sakura Gakuin member Miyoshi Ayaka is on the cover of the recent issue of "Seventeen" (Japanese version). Ayaka appears in every issue, but this is her second solo cover. The first was the September 2014 issue.
And if Japanese fashion magazines for teens interest you, another former Sakura Gakuin member, Sugimoto Mariri, also appears monthly in "Pichi Lemon" magazine.
If Sakura Gakuin and all of its members past and present interest you, make sure you pick up copies of all of these like I am!
