A Certain Magical Index/Characters/A Certain Scientific Railgun Supporting Cast

Here we present principle supporting cast of the To Aru Kagaku no Railgun spinoff of the To Aru Majutsu no Index franchise.

 * A-Cup Angst: Also pointed out by one of her students, although in reality she's about average.
 * Adorkable: Super-Deformed mode, after being scolded by Kuroko and Saten for taking off her stained skirt: "But no man would take interest in my flat and unattractive body anyway." Aww...
 * Anti-Hero
 * Badass Bookworm
 * Badass Teacher
 * Cloudcuckoolander: "My it's getting hot; time to take off my blouse... hey what's wrong?"
 * Cool Car: She drives a Lamborghini Gallardo! ... That's one hell of a salary she's got...
 * Ditzy Genius: Very intelligent, but lacks a shred of common sense.
 * Hot Scientist
 * Hot Teacher
 * I Am Not Pretty: Unfortunately, that the way she sees herself.
 * Innocent Fanservice Girl: "Why are you so concerned? My skirt got dirtied, of course I should take it off,"
 * Mad Scientist: "Not quite normal" is putting it politely.
 * Nerds Are Sexy: Sadly she doesn't see it.
 * No Nudity Taboo: While she doesn't get totally naked she seems surprised that people get upset when she removes her top or skirt after they get soiled or if she's too hot.

Mii Konori

"Voiced by: Kana Ueda"

A high school student and Chief of the 177th Branch of Judgment, where Uiharu and Kuroko work. As their sempai before becoming chief, she tries to make sure both girls do their work at Judgment seriously and at the same time want them to be safe. She is a Level 3 Esper with a power called Clairvoyance which, despite what the name implies, is actually X-ray vision. -
 * Ascended Extra: Originally a nameless member of Judgment in the manga, her role was significantly expanded in the Railgun anime.
 * Authority Equals Asskicking: Averted in that, although she has a lower Power Level (Level 3) than Kuroko (who’s a Level 4) she actually outranks the Lovable Psycho Lesbian in terms of bureaucratic authority.
 * And as shown in the omake of Railgun's Manga Volume 5, in terms of raw skill she is more-than-a-match for Kuroko as a Martial Artist.
 * Badass Adorable
 * Badass Biker: It comes in awful handy when you’re younger friends need to get to a battle “fast.”
 * Boobs of Steel: The strongest physical fighter in her branch, and also the most well-endowed.
 * Bring My Red Jacket
 * Cool Big Sis: To the younger girls in the Railgun cast.
 * Dark and Troubled Past: Linked to the fact that she was once a member of a gang of...
 * Delinquents: Which’s a diametric opposite of the side of the law she’s on right now.
 * Desperately Looking for a Purpose In Life: What led to her joining Big Spider, and subsequently Judgment.
 * Gainaxing
 * Heart Is an Awesome Power: X-ray vision may not seem to be that impressive on its own, but when that means never being surprised by concealed weapons, coupled with her bone-breaking martial-arts skills, it makes her more than a formidable match in battle.
 * Hello, Nurse!: The scene where she appears in her delicious swimsuit.
 * Improbable Age: She's the chief of the 177th branch of Judgment, which is justified since all members of Judgment are young Esper students.
 * Meganekko
 * Ms. Fanservice
 * Nice Girl
 * Reasonable Authority Figure: More of a "Good Cop" than Kuroko in the Judgment Brigade.
 * Specs of Awesome
 * Stupid Sexy Flanders: So devastatingly sexy in her swimsuit that she's able to provoke this reaction from the straight girls of the cast. And the Misakasexual. And a female snake.
 * Team Mom: When a voice of calm and mature reason is needed amongst the girls.
 * Together Umbrella: She drew one which had her name and that of her sempai at one of her old hangouts when she was a delinquent, but said sempai scratched it out, believing that kind of relationship wouldn't work out for them and because he wanted her to have a better life.
 * X-Ray Vision
 * Younger Than They Look: She's a high school student? With that body?

Wataru Kurozuma


"Voiced by: Katsuyuki Konishi"

Kurozuma Wataru is character introduced in the Toaru Kagaku no Railgun anime. He is a Skill-Out member and is the founder and former leader of one of the largest Skill-Out factions, Big Spider.


 * Badass Normal
 * Berserk Button: "You're hitting girls? That is not cool."
 * He'll also kick your ass if you make him drop his milk
 * Big Brother Mentor: To Mii Konori, who he sees as a surrogate little-sister. For Mii's part, she wishes it were something more.....
 * Chivalrous Pervert: The rare anime male that can sincerely make comments about a girl's figure without causing offense.
 * Face of a Thug: Averted; in spite of being the singular most Badass Level Zero in Academy City, he has easily the kindest and gentlest appearance of all the males in the franchise, Touma included.
 * First Love: For Mii Konori.
 * Katsuyuki Konishi
 * Casting Gag: He has a few parallels with Kamina, Katsuyuki's most famous role: both are eccentric Badass Normal Delinquents with signature tattoos and virtually the same "voice" out of Katsuyuki's many.
 * Nice Guy
 * One-Man Army: Stands out in Academy City for being a real Level 0 (unlike Touma) who is able to neutralize dozens of armed combatants, including those with firearms, with his Martial Arts abilities alone. It's quite likely that it's through his tutelage that Mii is such a formidable Martial Artist herself.
 * Put on a Bus: Literally, to jail. Do note though that he and Mii parted on very good terms.
 * Tattooed Crook: Subverted; his tattoo, which is badge of his loyalty to Big-Spider, does not stop him from being a kind gentleman and absolute sweetheart.
 * We Hardly Knew Ye
 * Wife-Basher Basher: Plays it straighter than Touma.

Therestina Lifeline


"Voiced by: Sayaka Ohara"
