Regarding the blurb in the title panel describing a video that I presume will give us our first glimpses at the upcoming fifth season of Minami-ke, I checked the Kodansha Young Magazine Youtube channel and the only Minami-ke video I could find was this promo from 2012 advertising the Minami-ke Omatase OVA that shipped with volume 10 of the manga.
Lots of videos of gravure idols on Young Magazine's channel, but not much anime/manga content.
