Warning: This is not a story. It's a giant fight scene. It was never really meant to be a story, though some parts may make you want to get to know the characters more. If you like fight scenes though, have fun.
Every morning, just a few hours after having breakfast, Ace Blade trains. Every evening, just a few hours before bed, she trains again.
Being one of the best guards in Equestria, she's allowed to use the more expensive equipment; she's allowed to wear lightweight armour, carry bladed wings with shock absorbers, and use anti-magic crystals on her enemies. She also gets access to the magical training grounds, and oh man is it great.
By the way, you're free to watch. Just don't get in her way.
