Don't have any more question marks on my title list, so I guess this is complete...for now. I'm translating the title names for fun.
Anything you do doesn't count for the title if you cannot see the title in the title list. To get the title to show you'll usually have to do something related to getting the title itself.
Also, I can't remember some of the prerequisites since they don't show after you've got the title.
With new dungeons come new titles. Update time!
