Kihara Family

The Kihara Family (木原一族) is one of the largest gatherings of scientists that work for Academy City's dark side and the forerunners of the most twisted human experiments. As a result, many if not most of them are highly influential scientists with high-ranking posts over multiple organizations under Academy City. The Kihara Family serve as a recurring antagonistic force in the series.

Etymology
Kihara is written with the kanji of tree "木" and field "原", and may be a reference to them being prolific, having thousands of members in a single bloodline.

Principles
The one trait that all Kiharas have in common is a natural aptitude in science, as well as the gravitation of their actions to the most evil to most human standards, this is exemplified by Kihara Enshuu, who, without being taught anything, was able to escape imprisonment and kill her captor in a horrific way.

The Kiharas completely ignore all moral and ethics of science and humanity for sake of experimenting. Due to the fact that all family members are highly intelligent combined with no sense of morality; the results of their experiments have yielded tremendous success at the costs of traumitizing or killing many people. This blatant disregard for human life extends to their own kin, as with Therestina Kihara Lifeline and Kihara Nayuta were both experimented on. As well as Kihara Byouri attempting to kill Enshuu, just for turning her back on her, as well as Enshuu attempting to kill Byouri in turn with no problems on her conscience.

If Academy City, the bastion of science, were to be destroyed, Kiharas would simply spread throughout the world. They reside in Academy City because it is the capital of science and nothing else bounds them to it.

Genealogy
In the beginning there were seven normal people, who later fell into madness and villainy, knowing full well of their actions but unable to stop themselves, as the concept of "Kihara" begins crystallizing, a family dedicated to the pursuit of science whatever the cause, using themselves to define it. It is implied in the narration that Aleister Crowley had a hand in the creation of the concept of the "Kihara". The concept of the "Kihara" is apparently a recent phenomena as it has not been a hundred years since the concept has taken a clear form.

Currently there is actually a single bloodline numbering over 5000 that possesses the family name "Kihara." Whenever a person desires to misuse an area of science without any care for the consequences, a Kihara is the one to do it. Even if they are currently bound by a single bloodline, it is not a necessity as others can take up the name if it was to be wiped out, meaning that one needs not be blood-related to become a Kihara,  as proven by the existence of Kihara Noukan. Kihara Byouri also mentions on how so long as there is still humanity continued to rely on the benefits of science, the family will exist, and that it would take the complete destruction of all cultures in the world for them to be defeated.

Kihara Kagun also mentions that there is some sort of qualification necessary to be one as when he meets Enshuu he says to her "I had heard you had not yet qualified as a Kihara."
