For the longest time, Diamond Tiara was a bit of brat. She only cared about her image and constantly mocked other ponies. But time passes, and things change. Now, an older Diamond Tiara wants something greater in life. No longer does she want to merely enjoy the wealth of her father, and she never wanted to take over his business. No, now she wishes to become a member of the royal guard that serve and protect Princess Twilight Sparkle, and maybe some day, reach the rank of captain.

Does she have what it takes to become a guard and rise through the ranks? Or is she still too much of that little self-absorbed brat to do what is right?

(Currently tagged as Slice of Life due to focusing on day to day events of training, Romance for feelings between two characters,and comedy for some humorous parts. Although not actually gory, there are scenes with blood and violence.)
