Where can you get a 5th Night Star Gem?

Hi, guys.

I was wondering where I can get a 5th Night Star Gem? I need a 5th one so all 5 characters can have them and be Leveling up their Ranks in Magic. As of now, Caldina is without the ability to grow past Level 50 in Black Magic, and I'd like to rectify that before things get too much farther, if I can.

For referehnce, I just left the Gardenia Prison and headed to Cougar's village, Alpicoco.

Thanks in advance for any help you guys can provide.

So, it seems a 5th Night Star is obtained from defeating the Griffon at the mountaintop north of Alpicoco Village.
