Theodosia Electra

Theodosia Electra (テオドシア＝エレクトラ) is a Necessarius magician who uses Norse mythology as a base for her magic.

Appearance
She has an appearance of around 40 or possibly a little younger. Her hair is a mix of blonde and silver, but it is simply because her hair was damaged. She wears a baggy white top and faded white jeans.

Toaru Majutsu no Index SS: Stiyl
She temporarily betrays Necessarius to protect Patricia Birdway from them when she turned down the offer to work for them.

The First Friday of February
Kanzaki Kaori tells the Jeans Shop Owner that she got her information on the Jeans Slasher's actions having the smell of Norse Mythology on them from Theodosia who investigated the incidents.

Abilities
Stiyl comments that she constantly changes what main spell she uses, because she was either very talented or just an idiot who got tired of things quickly. Though no matter the changes it always remains a Norse magic based spell. When he meets her she is using spells based on fairy tale of the Little Match Girl in various ways:
 * 1) Visual data display: Shows information to the person lights it for as long as the match is lit.
 * 2) Darkness: The area becomes spread in the same way darkness was pushed away by the light of Theodosia’s match.
 * 3) Hand grenade: Match is tossed at the opponent like a grenade then it explodes creating a series of chain explosions to make a fire wall.

Other spells

 * 1) Skírnir’s Staff: It is a spiritual item with four runes carved into it, based from Norse mythology from Iceland. She was able to combine the flames used to protect treasure and the staff used to steal treasure by optimizing the original pattern for the layout of the runes.
 * 2) The Drill of Rati: Based on a story about Odin functions as a charm that will allow one to sneak into difficult places and to escape from them. She smashed it into a powdered form so she could carry it around with her, to make the person cornering her on the edge of death flinch. She was able to turn it into a way to revive herself from the dead.
