Toaru Kagaku no Railgun S Episode 19

is the nineteenth episode for the second season for the Toaru Kagaku no Railgun anime adaption, and the forty-third episode overall. It was first broadcasted on August 23, 2013.

Mikoto and the others find a strange girl collapsed in a park flower bed. The girl says her name is Febli and knows Mikoto's name for some reason. Mikoto has no idea who the girl is and Judgment has not received a notice of a lost child.

Febli takes a liking to Saten, so Saten and Uiharu work together to look after her. The next day, they check photographs from various databases but find no data on Febli, so they treat her as a Child Error. Febli is accepted into Cypress Park, but they must look after her for the five days until she can enter.

Mikoto struggles to get her to say her name, but...

Animation Trivia

 * Erii's height fluctuates during this episode, specifically in the outside shot of the Judgment 177 Branch Office, she is shown to be taller than all of the girls present there, including Mii.
 * The walking animation for the gang as they try to go to Cypress Park is poorly animated, with the girls barely moving their bodies and the illusion of their legs moving faked by having them "moved" up and down, especially that of Febli, whose legs aren't shown allowing for a easier way to hide her walking.
 * During the scene where both Mikoto and Febli are sitting on the same bench, the shadow for Mikoto's blouse goes over a line. This is quickly corrected after Mikoto flinches when Febli doesn't respond to her.
