Is there more stuff to unlock after beating the story missions?

[Sarthraa]

Well, I assume you see the title. ^^; Anyway...I've beaten the story mode, but...it seems like some of the clothes and parts are missing. I know in PSU:AotI you had to beat, er...that mission with Mother Brain on S rank to unlock the final items in the shops. Is it the same way in PSPo2, or are there other requirements?

I've only done one client request, and the highest open mission I can do is B rank. I think I've S-ranked the first 2 side story missions, but I have yet to do the 3rd one.

Any help on this?

More clothes and stuff are available for purchase after the hard story mode is clear. Some new quests are added/updated too.
