Have you learned the normal Sage True Form?
The order is True Form level 3 > Sage True Form > Sage True Form Mighty > Panda Form Sage
Scroll down in the boutique to find the Sage True Form book.
As for entering GV, you need 2 people to open it. You shouldn't need an item to get into GV, only to start the quest inside, which is done with Rebirth orders, I believe (long time since I did one). I thought Duty Badges were for Cube only.
Reawakening is disabled on this server.
Hope that all helps.
