I've looked at vocaloid backpacks myself they are expensive! Although I never really thought of them being very gender specific, so I'm not entirely sure what your looking for but,
link link link link bạn can also find a lot of stuff on ebay, I would make sure the place your buying from can be trusted. As far as the game goes, which one do bạn want? The game is licensed bởi Sony and there are only versions for the PSP, PSP Vita, and PS3, of which multiple games are on each, did bạn have a specific one in mind? I'll assume project Diva F since its the newest and the only one with an official English release, (i think bạn can download English patches for the others) its for the PS3 and I believe the English release comes this August :D bạn can pre-order it from gamestop
link its says it won't come out until Dec.31,2013 but that's actually just a place holder for the site since no official ngày has been được trao for its English version. So preorder and wait for August and hope Sony doesn't delay! hope this all helps!
