In Modern Society, many assume that Chivalry is dead. But for three friends, it's quite the opposite. When Kristine, Mallory, and Nicole decide to cosplay as some of the warriors from Fate/Stay and Fate/Extra, they thought it would be fun to purchase the weapons to go along with the costumes to complete their look. Turns out, it was a bad idea. A VERY bad idea. Now the three girls are asked to serve as bodyguards for two young princesses while learning how to control their powers and learn what it means to fight with honor. This is definitely not going to be easy.
