6th Mar: There is an option now on your profile page to use "compact" folders. This works pretty well for phone users and others who like less scrolling.
Tropes about those who provide protection to others
This is on a smaller but more person scale then Index to the Rescue. These people guard, protect, and defend those they are responsible for from danger. If it's about an actual shield then it's found under Tropes in Shining Armor.
