Brunhild Eiktobel

Brunhild Eikdopr (ブリュンヒルド＝エイクトベル) is an antagonist in Toaru Majutsu no Index: Kanzaki SS, a special story of Toaru Majutsu no Index released as an addition to the DVD and Blu-Ray releases of Toaru Kagaku no Railgun.

Appearance
She has a very long and curly blonde hair and her clothes are strange in some way. She wears a feathered cap, one piece dress, pants, knee and elbow guards, and a breast plate. It looks really messed up, but in the magic sense, her clothes form a set of medieval armor. The weapon that she used is a Claymore, which is a huge sword that can deal substantial damage even without any sort of skills or tactics. However, it is clear the Brunhild is skilled at using the sword.

Background
Brunhild was a part of a small cabal that was destroyed 5 years ago. Being born as a Saint other Norse magicians thought that her Saint side corrupted their history and culture, and that she was a disgrace. Thus they called her "Hel". So the 5 most powerful Norse myth magic cabals teamed up and destroyed Brunhild's cabal. They captured and tortured her for the sake of getting the final rune and gungnir. In order to get her to talk, the tortured her. However, they didn't do any irreversible damage to her body, and they didn't sexually abuse her. This is not because they cared about her. It's because once she breaks and gives up, it would be impossible to get her to talk. Instead, they kept on torturing her, but leaving her with a glimpse of hope each time. During that time, she met the person who delivers food to her prison cell, a 10-year-old kid. That kid wass the only one she could talk to normally, and eventually opened up to him. Eventually, the kid apologized to her, saying that he was ordered to talk to her to soften her up for more torture. The kid kept on blaming himself for not being able to do anything to help her. It's then that Brunhild decided to help the kid. For that, she decided to endure the pain and patiently wait until her power recovers.

One day when her power has almost completely recovered, one of the magicians who tortured her showed up instead of the kid. The magician told Brunhild that the kid attempted suicide because of all the guilt he felt. The magician showed Brunhild a note that the kid wrote. It said "I'm sorry I couldn't help you". Immediately after, Brunhild snapped and broke out of the facility.

She single-handedly destroyed the Five Great Norse Societies:


 * 1) Those Who Nurture the World Tree.
 * 2) The Knowledge Carved Into Iron.
 * 3) The Champions Rising from the Sea.
 * 4) Those Who Know the Words of God's Sword
 * 5) The Golden Forged Hammer in the Earth.

After being found to be the culprit behind the attacks, she is chased by Kanzaki Kaori who manages to corner Brunhild on her first fight and, later she manages to acquire Gungnir replica which can manipulate the forces of the nature and fought once again against Kanzaki Kaori but still lost.

The real reason behind the capture half a year ago was not to stop Brunhild from corrupting the Norse myth community. It was to get Brunhild to talk about the Gungnir and the final rune. Also, the kid who committed suicide is still unconscious in hospital. Kaori realizes that Brunhild isn't doing this for revenge. Rather, she wants to use the powers of a God to save the kid.

She orchestrated most of the events in the side volume to gain a method of carving the final rune in the earth, so that it and Gungnir couldn't be destroyed.

In the end she was defeated by Kaori and turned over to Necessarius, who plans to ask Brunhild about the Gungnir, the final rune and the how she planned to carve it onto the core of the Earth. However, since records show that torturing probably wouldn't get her to talk. As such, they plan to bring the kid, who was really under a spell to prevent him from waking up, in and use him as a negotiation tool to get Brunhild to talk.

 * Bodies Regeneration's Halt
 * Stigma
 * Bodies Hijacking
 * Valkyrie's Norse Magic Style
 * Gungnir (only at 70%) - Gungnir has the ability to perfectly control weather and other natural occurences. She attacked Kaori with thunder, magma, water and even created large amounts of salt to damage the ground that Kaori was standing on. She can do all these with just 70%. There is no concept of elements in Norse myth. Brunhild triggered those elemental attacks by different combinations of fire, ice and frost symbols. This forms a trinity - a symbol of Christianity.
 * Final Rune
