Brunhild Eiktobel

Brunhild Eiktobel (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. She is reintroduced in Shinyaku Toaru Majutsu no Index as GREMLIN's efforts advanced, having to team up with Ollerus and his ilk to prevent Othinus from completeing the true Gungnir.

Etymology
Her name is a likely reference to Brynhildr, a shieldmaiden and a valkyrie in Norse mythology.

Moreover, in Norse mythology, Hel is a being who presides over a realm of the same name, located in Niflheim, where she receives a portion of the dead. Hel is also referred to as a daughter of [[Wikipedia:Loki|Loki], the Norse god of misfortune, and to "go to Hel" is to die.

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.

Personality
Brunhid is shown to be very caring for people that she cares for, such as Ceillier Flatley, and is utterly merciless to those who harm them, as shown with her battle against the Artificial Valkyrie.

She has shown to be at least trusting when it comes to teaming up with other people. Despite not knowing where Ollerus was or his plan was, Brunhild paid no mind to it, only asking until everything has been concluded. She went along with Silvia, not putting much up of a fight against Misaka Mikoto despite her being capable of much more. What's more, she is shown to be cool-headed and taciturn. She doesn't tease Leivinia Birdway, nor reprimands Silvia for her teasing, casually holding out her hand to prevent any serious fight between the two. She doesn't needlessly talk much unless she needs to or is spoken to by others.

She shows some pride on being a valkyrie, and dislikes things that befouls it, such as valkyrie bikinis.

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, they 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 was 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.

Toaru Majutsu no Index: Kanzaki SS

 * Main article: Toaru Majutsu no Index: Kanzaki SS

She single-handedly destroyed the Five Great Norse Societies.

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.

Baggage City Arc

 * Main article:Baggage City Arc

Brunhild reappears in the main novel series as a free woman, the charges against her being dropped after she cooperated with her captors, the Church of England, during World War III. She was able to reunite with the boy she wanted to save, now awake in a hospital in northern Europe. But on the same day the Kihara's assaulted the Natural Selector tournament at Baggage City, artificial Valkyries sent by GREMLIN launched an attack on her while she was at the hospital. At first she was outnumbered, but the Saint Silvia and Leivinia Birdway came to her rescue. However, the attack was a distraction as the battle allowed a GREMLIN agent outside the hospital to grab the plans for Gungnir from Brunhild's mind with her mental defenses lowered. Siliva assured her that they can track GREMLIN now to their base of operations.

Ichihanaran Festival Arc

 * Main article:Ichihanaran Festival Arc

Eve of the Festival
She is apparently a part of Ollerus' group, along with Silvia, Fiamma of the Right, and Leivinia Birdway. Entering Academy City in order to oppose Othinus and GREMLIN, who plans to capture Fräulein Kreutune, despite the fact that they could've intercepted them outside of Academy City, though chose to have the battlefield in Academy City in order to interfere with GREMLIN's teamwork, as Thor noted.

During the Festival
Brunhild is with Leivinia Birdway and Silvia, the former takes them to a location in School District 12, after Leivinia was tricked by a ruse by Touma to distract them from getting Fräulein. Here, Silvia mocks the building trying to imitate a Buddhist temple, not having any actual magical symbol, to which Brunhild agrees. As they converse about the queer religious building in the city of science, Leivinia calls for their attention if they had found any signs of Marian Slingeneyer yet. Silvia tells that she should already know the answer when they have not come upon any traps on the way in. Leivinia asks if they were tricked to which Brunhild says that they were most likely have, and states that Touma has indeed grown if it had in him to plot like this in the sitauation that he was in. Silvia tells Leivinia not to be upset, saying that after Leivinia tricked him so much, she shouldn't have any right to get mad when her returned the favor just once. However, Silvia adds on how she understands why she is panicking, as what Touma did costed her the perfect chance to apologize to him. Her reply only makes Leivinia angry, threatening her. Brunhild then asks why should they do next. They conclude that since Touma had no reason to make them think that he had connections with Marian, then he must've done so in order for him to distance them from something—something that they would come across naturally had it not been for the efforts of Kamijou Touma.

While continuing on their way, Brunhild and the others passes by Kumokawa Maria and Tsuchimikado Maika. She questions Japan's term for maids, but Brunhild states that they are just costumes for the festival and pay no mind to it. However, her opinion quickly changes as the beauty contest from Eiri High School is broadcasted, having a girl wear a sexy valkyrie bikini outfit, much to her chagrin. Of course Silvia rubs it into to her by saying that it too was a festival costume. Brunhild then mentions that it is because she doesn't like that image forced into her, especially since there are already perverts like that wearing bikini all year. Silvia smugly comments on how nobody would depict Valkyries in such a way if no one had ever wanted them to be sexy, citing their roles in Norse mythology, as spouses of warriors, servers of alcohol, and dancers of bewitching moves. Silvia stops talking however just before Brunhild really did become angry. All the while this is going on, Leivinia keeps silent, still frustrated.

As the battle between Accelerator and the revived Kakine Teitoku rages in School District 7, it is heard by the group. Leivinia becomes interested by the ruckus, as it could be their only lead even if it is a decoy. Brunhild talks about of who lies behind the fog of war, as a battle against them might become draw out. Leivinia replies that it might Touma, saying that he might be working with someone and that she sometimes can't event predict how his mind works. Silvia smiles and asks if Leivinia is simply a sulking child that was after the older neighborhood boy she relied on moves on and leaves her behind, and asks if she is surprised that she underestimated the person she looked down on. Leivinia deems that Silvia is simply making fun of her, and gets angry. Silvia continues and says that Leivinia's anger is misdirected and childish, and should consider herself lucky that Touma didn't get her back much worse than what she did him. In that restauran where they rested, the air had killer intent. Silvia keeps on talking and implies that Leivinia is just manipulating Touma in order for him to safely drop out of this dispute with GREMLIN. However, at that point Leivinia attacks, but is quickly restrained by Brunhild. Silvia is hit, but with only a single drop of blood of trailed down the corner of her mouth, who kept on smiling. Leivinia demands to know where Ollerus is, to which Silvia says that he is preparing. With that, Leivinia stays her hand, and tells them that they should go.

Leivinia soon finds Fräulein Kreutune in the multi-level overpass, and is forced to engage against Kamijou Touma for her fate. Silvia and Brunhild that was supposed to support her, are confronted by Thor of GREMLIN and Misaka Mikoto of Academy City, respectively. And so, magic and science clashed, Brunhild of the magic side, one of the 20 Saints in the world, against Mikoto of the science side, the third ranked Level 5 esper of Academy City. Despite the fierce titles bestowed upon the two, the battle seemed one-sided, for great speed Brunhild held, and her steps if she wished were faster than sound. Brunhild chaged towards Mikoto and swung her sword down her like a steel fan. But Mikoto reacted before the blow, and with her powers moved a part of the road they were on, putting Brunhild's aim off, but its power was immense still, and many glasses were shattered the instant it fell. Brunhild questions Mikoto's ability to know where she was despite her speed, not knowing that her powers allow to control iron sand on the road's surface and allow her to see her footprints. And with that same iron sand did Mikoto use to consume Brunhild inside like a storm of needles. But no harm came to Brunhild, for she swung her claymore in a circle, and the iron sand was blown away in a roar. The force her swing threatened to knock Mikoto down, but she escaped by magnetizing a wall between before it struck. Mikoto tries to gather the iron sand once more, but Brunhild came upon her and aim the sword upon Mikoto's neck. Mikoto used her powers to forced the blade to halt, but Brunhild's strength overcame it for her to swing it. But it was enough time for Mikoto, and a lightning spear struck the sword and Brunhild. Mikoto did not allay her attacks, for she swung towards Brunhild many reinforced concrete objects. However, Brunhild recovered from the shock, and with her strength stopped the mass of objects that Mikoto flung towards her.

As if acknowledging Mikoto as a worthy foe, Brunhild speaks to her, asking why she is participating in this conflict for Fräulein Kreutune if she had little to do with magic. For a great risk did Mikoto bring upon herself when she wraps herself in the core of GREMLIN. Mikoto tells Brunhild that she doesn't want to hear from someone who is trying to kill her, and straight to the point, does not know nor care about the big picture surrounding their conflict. Moreover, she says that she has no good reason to be fighting. However, Mikoto says that there is not a need for a good reason to save a friend, as what her friend once said, and now, she will support him in spite of the dangers that will befall him. With that, Brunhild cut down her obstacles and made an opening for her with her sword, and the same time, Mikoto swung her iron sand sword. Colliding, Mikoto saw that her vibrating iron sand sword could not slice the claymore, and released it. She then took a coin, and fired her Railgun towards Brunhild, shouting that she has her own reason to save Kamijou Touma.

Despite the apparent nature of letting her guard down against Brunhild, Mikoto took the time to use her eletromagnetic powers to control Leivinia Birdway's gun before she could fire it. This and Thor's later use of his fusion arc blades to cut up the road between them, allowed Touma to recover enough in order to fight Leivinia anew.

However, with the defeat of Leivinia Birdway at the hands of Kamijou Touma, Brunhild stops her attacks, her sword covered with various objects that Mikoto stuck into them to slow her down. And Mikoto did not dare take advantage of the opening. Mikoto asks what's the matter, to which Brunhild says that the issue has been resolved, and she is unsure if she should continue fighting, head over as reinforcements, or view the situation asunfavorable and make preparations to reorganize. As what happens later, Silvia takes the last option, and the conflicts in the multi-level overpass ends.

As they leave Academy City, Silvia complains on how what they did was a complete waste of time. Leivinia replies that it couldn't be helped, and states that even if they did want to get Fräulein, she can't be used to lure Othinus anymore. Silvia asks her if she is still affected by being forced to fight Touma, saying that even if she cannot accept how it ended and even if it was based on Touma's reasoning she cannot understand, she cannot complain after she lost, infuriating Leivinia. Silvia continues to tease, comparing her to a little sister that got scolded by a big brother whom she thought would always listen to her, and whom tried to talk things out to her after all she did to him. Leivinia threatens to use her full Major Arcana on her, to which Silvia points out on how Leivinia didn't use it against Touma, knowing that it would give her an advantage, showing a big grin all the while. Brunhild then interrupts, asking about Ollerus, whom Silvia said earlier was preparing. Silvia replies that he is dealing with their true purpose, one that has nothing to do with Fräulein Kreutune, and told them that the preparations are complete.

Quotes

 * (To Silvia from NT6): "I get it worst when it comes to having that kind of image forced on me… In fact, there are even some in the magic world! There are self-proclaimed maidens of battle that dance around all year in a bikini like some kind of pervert!!"
