^ Amped mentioned it in the last page along with a preview of the PV.
I especially love the dance closeups in Tsugi no Kado wo Magare. These girls just look amazing, their outfits stylish, and their dancing explosive, its great

Can't help but think how this KSS backup dancers is similar to how Sexy Zone has Johnnys Jrs as backup dancers for them in several PVs (except there's an army of them >.>)
Though, regardless, I am guilty of just looking towards at the background sometimes to see Kaedi dance

For Middle Management, I like the song more now that the H!S ver is out. The dance looks interesting and the line distribution seems pretty balanced, so Im glad to hear everyone sing atleast a few lines. Still think it was a bit too much on the robo effect but I think ill grow out of that soon enough.
