Febrie

Febri (フェブリ) is a character introduced in the second season of the Toaru Kagaku no Railgun anime adaption. A young girl who often has a piece of candy in her mouth, she becomes the core to the Silent Party Arc, and is considered to be the "Railgun team" mascot.

Appearance
Febri is a petite girl with long cream hair, with two ahoges sticking out of at the top. With purple eyes, she dresses in a black and white dress stereotypical of that of a Gothic lolita like Nunotaba Shinobu. She carries with her a heart-shaped satchel, and characteristically always has a piece of candy in her mouth.

Personality
She is quick to friendship but slow to amend grievances, as demonstrated by her antagonism towards Misaka Mikoto. She is also stubborn, willful, and is easily distracted by Gekota. She is relatively quiet as she often has her lollipop in her mouth. This lollipop has a strong taste that not even the older girls around can take it. She also loves the rare pink gekota that she took from Misaka during their first meeting.

She is trusting of people, and to those who are her friends refer to them by their given names.

Background
She is referred to as "the youngest girl to appear so far" (in the anime), though it is unknown how old she truly is. After she came down with a fever that was "uncurable" and not a human disease but poison secreted by her body's cells as determined by the Heaven Canceller, she is said to be fully, scientifically man-made. Her lollipops appear to contain a compound that neutralises the said poison. She seems to have a connection with Nunotaba Shinobu, as well as the fact that STUDY knows her and tried to kill her.

Actually, STUDY made her as a 'spare' for Janie. It was also revealed Nunotaba Shinobu was the one who let her escape from the facility.

Silent Party Arc
She first appears watching from the distance the fire that started in a warehouse due to the fight between ITEM and STUDY's Powered Suit. For reasons unknown, she later opts to sleep in flower garden in a park. She is later found by Misaka Mikoto and the gang, and after much prompting, with the help of Saten Ruiko, starts talking to them. She confides to them her name, as well as saying Mikoto's name non-sequitur. When Mikoto introduces herself to her, she becomes antagonistic despite being friendly with everybody else. Mikoto spends the most part of the next day trying to win her affections. As there is no way to contact Anti-Skill in the late hour they met, she is taken in by Saten Ruiko and Uiharu Kazari in the latter's home and enjoy their evening, as Febri has taken a liking to the former.

The girls later decide to hand her over to Cypress Park after there was inconclusive search on her in their databases, and as taking her in requires 5 days, the girls take her to the venue for the Academy City Research Exhibit Assembly, as Shirai Kuroko and Kazari, being Judgment need to prepare the security of the venue their. Ruiko later takes this chance to have her bond with Mikoto, with them leaving the both alone. Unfortunately, Febri wanders off after seeing a large Gekota picketing around (Aogami Pierce in a costume). She is later horrified that Aogami is behind the mask, gets lost further and finds herself in the sights of Aritomi Haruki, who and his compatriots in STUDY are looking for her. He attacks her with Security robots apparently trying to test her skill, but is later saved by Mikoto. She later bonds with Mikoto, apologizes for troubling her, and later plays with her.
