Fate/Extra: Nero Claudius

She's the Saber-class Servant available to be chosen by Hakuno Kishinami in the Moon Cell Holy Grail War. Her real name is Nero Claudius Caesar Augustus, the 5th Roman Emperor. She was an infamous tyrant whose once rule was made up of schemes and poison as she oppressed all religious forces, especially Christians, and the Roman Senate during the period from 50 to 60 AD. In her past, she was also a very competent judge who brought in several important lawsuits with her fairness and efficiency. She also had a level of haughtiness that seems to more than compensate for her short stature. There are a lot more of her in the Fate Extra games and Last Encore. Her Noble Phantasm is Aestus Domus Aurea: Golden Theater of the Flamboyant.
