Kihara Noukan

Kihara Noukan (木原脳幹) is a character introduced in Shinyaku Toaru Majutsu no Index. He is a member of the Kihara family and is first referred to in 4th Shinyaku Toaru Majutsu no Index novel, as a golden retriever by Kihara Byouri in Baggage City.

Etymology
The Kanji for Noukan literally translates to Brainstem (an important part of the brain that is located just above the hypothalamus).

Appearance
He is a golden retriever with arithmetic circuits externally attached to him.

Background
Despite being a dog, Noukan is capable of human speech, and has the voice of a man who seems to be in the prime of his life. Furthermore, he is said to be the most influential of the Kiharas in many different fields, as shown when he offered to Kihara Yuiitsu rich people who are dumb enough to be used in one of her experiments.

Due to the fact that the Kihara family is still a single bloodline, it can be asumed that Noukan was at one point human.

Agitate Halation Arc

 * Main article:Agitate Halation Arc

He is given a walk in School District 13 by Kihara Yuiitsu the morning after the events of the riot of "heroes" in Learning Core. He and Yuiitsu apparently had a hand in manipulating the "heroes" from stopping their rioting after the defeat of Yakumi Hisako and Rensa. Yuiitsu commends Hisako for being a nice patron to her despite the failure of the project, to which Noukan replies that she may have been playing around too much. Noukan mentions on how Yuiitsu managed to implant her intellectual curiosity with Hisako but not being able to make Hisako to understand how a Kihara thinks. Yuiitsu laughs, recalling on how Hisako wondered on how they got along so well, and commended her for being useful to her research. Noukan however states that she went too far, but Yuiitsu says that she has learned her lesson.

Noukan then tells Yuiitsu of the top 3 likely candidates to become board of directors as insurance for her plans. But Yuiitsu simply vetoes it, saying that it isn't Kihara-like, prompting Noukan to ask of her plans. Yuiitsu then mentions the use of the Shadow Ruler plan, apparently an organization, to which Noukan throws doubts at such a convenience that she can use. Yuiitsu states that they will take action if they make them think there is a reason to take action, pointing out Academy City, the city of science, and its strange relationship with jinxes and urban legends. She says that she can manipulate a bit of information to make certain facts seem true, which will prompt them to action in lines with her schemes. She then asks Noukan to start deceiving important people. Hearing this, Noukan acquiesces to her plans, stating that he can give two or three people she could use in her plan, rich social climbers that are dumb enough to be manipulated by her. Hearing this Yuiitsu thanks to him as always.

With the Agitate Halation dead, Yuiitsu then asks what they should do about it. Noukan states he has no particular interest in but tells her that it might not be a failure. Noukan states that the Level 5s of Academy City gathered in one place despite Hisako's wishes, as well as Touma's appearance of his own free will despite the Imagine Breaker negating any influence from Agitate Halation. He tells Yuiitsu that even though the experiment ended in failure, perhaps Agitate Halation was simply too much for her to handle, and that there may still be something of interest. Yuiitsu agrees with his analysis, to which Noukan states that she never shows any motivation if he is not the one keeping score for her.
