Rory Mercury of GATE

Rory Mercury is a demigoddess and an apostle of Emroy, the god of war, violence, and death. Despite her antediluvian age, she has the appearance of a 16-year-old. Along similar lines, despite her delicate, petite frame, she is widely known as Rory the Reaper, Apostle of Emroy, who will slaughter her enemies with her giant halberd with no mercy. Her gothic lolita dress is an outfit for priestesses.

Rory has a friendly personality as seen when she immediately became friends with Yōji Itami and started sitting on his lap. However she shows no mercy to her enemies as seen when she slaughtered a gang of bandits without any remorse. In battle, she is shown to have a violent, sadistic personality, however, she is not without a sense of justice, often targeting bandits and criminals, while generally friendly towards the common people. After the two of them fight alongside each other at the Battle of Italica, Rory becomes friendly with Shino Kuribayashi, who shares a similar "warrior" mentality and high level of combat prowess with Rory.

Despite being nine hundred and sixty one years old, Rory has the appearance of a young girl of around twelve or thirteen as she has stopped aging when she ascended to become a living deity in a flesh and bloody body. She has long flowing black hair with a black ribbon as a hair ornament.

Rory is first shown wandering around the desert where she meets a gang of bandits. She heard their plans about attacking the refugees from Coda, so without any remorse she slaughtered every last one of them. Some time later, she appears walking alone on the road the Third Recon Team was taking to evacuate the city of Coda. Rory becomes intrigued by the Humvee being driven by Youji, and decides she wants to ride in it as well. Unfortunately she decides to sit in his lap, while he's driving. After significant arguing, they reach a compromise of sharing the seat, with Itami nearly hanging partway out of the vehicle. She travels with the wagon train in this fashion until the Flame Dragon attacks the convoy. She aids Third Recon in fending it off.
