Urajuusanke

Urajuusanke (裏十三家) is the thirteen inner clans which had topped the inner hierarchy of Japan until its modern period.

They are likely to be endowed with genetically physical and mental superiority and characteristic abilities, as they ruled the inner society of Japan with their prominent powers. In present time, more than half of the clan closed down their business or ceased existence. However, their names are still recounted as the embodiment of awe and remain strong influences in the inner society.

Only some of the clans pertain to illicit activities, but the more prominent members of the clans seemingly associate with these activities, except the Houzuki.

Yugamisora (歪空)
The clan genetically close to immortality as they are excessively capable of restoration.

The clan is also known as the most prominent of the thirteen inner clans.

Their hereditary business committed terrorism but now focused it abroad as the headquarters of the clan relocated to the United Kingdom.

The members of the clan never die without natural cause and they can cure any injuries and never get diseases, as they just last their longevity without other factors.

The clan treats favourable for dosing medicines of removing physical limits, so they can fight while suffering lethal flip sides of the medicine while curing them. However, they are merely humans even though their supreme vitality, as to which they cannot live without breathing.

The clan hates the Hoshigami because of the use of their fortified prostheses for immortality.

Benika Juuzaka considers that "They are not like monsters. They are monsters." and Myori Houzuki is reluctant to associate with the clan.

Kirishima (斬島)
The clan is known for novel prominence of swordsmanship, as they can treat any kinds of blades excessively in offensive and defensive ways.

When they grab blades, their disposition and physical strength dramatically turn into vehemently herculean. However, it is not under influence of Dissociative Personality Disorder, as they are "just" skillful of treating blades, not for techniques. There are individually different on altering personality.

The Kirishima entitle the name "Kirihiko (切彦)" to ones whom belong in the main lineage of Kirishima and succeeded the business of assassin.

The Kirishima can easily slay swordsmen without elaborate techniques of swordsmanship. Hence, those who dedicate to swordsman hate the clan.

They don't seem to exercise for physical strength much like the Houzuki, as for Kirihiko LXVI, whom apparently uses her own intuitive skill other than physical strength.

Not all of the Kirishima seemingly commit murder, as it's associated from conducts of Kirishima in "Kure-nai" and "Denpa Teki Na Kanojo".

Myori Houzuki considers "They are a little dangerous but actually simple and friendly.".

Houzuki (崩月)
The clan implanted horns into their arms as the fountain of strength of Senki, as the clan finally gained the ability of Senki after hereditary suffrage of excessive disciplines for physical strength. And the Houzuki innately own the horns in their arms.

The Houzuki Style is provided as the severe exercises of building durable body for becoming Senki.

They had already closed down illicit business since Housen. The clansmen are apparently gentle but become terrific when they get in fury as Shinkuro indicates their polarized disposition that they are gentle but excessively severe.

In present, the clan consists of Housen, the patriarch of Housen, his daughter Myori and her husband, his granddaughters Yuno and Chizuru. In addition, a disciple Shinkuro. although only 3 disciples belonged in including Shinkuro, but 2 of the disciples fled the Houzuki because of severity of the disciplines In the last century before the birth of Yuno. Even if anyone who is not part of the clan, they are capable to become Senki if they suffer the severe exercises and bring the horn into their arms.

The ones who transformed into Senki gain superior physical strength with a spike of any physical functions as well as the strength of their fists. The strength of Senki individually depends on their emotions, for example, Shinkuro triggered the bulge of strength with his own fury. But it seriously harms their physique and suffer quite kickbacks.

The Houzuki seem to be the unique clan which brought their proper ability to one who is not part of the lineage such as Shinkuro among the Thirteen Inner Clans.

Hoshigami (星噛)
The clan is known for prominent talent of tailoring elaborate prostheses, as they can produce artificial arms, legs, viscera and even genitals for anatomical substitutes of human body. Hoshigami's products are hardly dealt in and they seem to be mostly dealt as well as jewelry which weighs identical to the products and Hoshigami's technology of prostheses is supremely classified.

All members of the clan replace congenital organs with artificial ones such as for Zena Hoshigami.

The clan deeply pertains to the establishment and management of Akuu Company in hereditary relevance, as Zena supervises the company.

The clan hates the Yugamisora, genetically close to immortality, although the Hoshigami artificially become close to immortality with their own products.

Myouri Houzuki considers that the clan behaves businesslike and ruthless, but harmless without interfering to their business.

Ochibana (堕花)
In present time, the clan had already closed down their original business much like Houzuki.

A character whose name is identical to "Ochibana" appears in "Denpa Teki Na Kanojo", under the undefined relativity, but apparently for which the author of Kure-Nai also wrote it as a predecessor.

Endou (円堂)
The clan seems to immerse into public authorities such as to influence over police section.

Utsuromura (虚村)
The clan had disputed with Houzuki in somewhat times.

Ajou (亞城)
The clan has contacted with Houzuki since Housen's offering to tailor bullet-proof and blade-proof leather jacket which young Housen wore.
