Tamamo Irigami

Tamago Fujiwara (藤原卵, Fujiwara Tamago) is an S-Rank kunoichi and accomplished medic-nin, currently in exile. Tamago was affiliated with the now-extinct Hidden Village of Yugakure, and to a greater extent, the Fujiwara clan, to which she was born. However, her role in the Black Egg Affair led to her excommunication and subsequent status as a missing-nin.

Background
Fujiwara Tamago was born in what was once known as Yugakure to two of its shinobi. Her father, Kurokawa Kazuma, had been wed to her mother according to the Fujiwara custom of bride theft (only in his case, it was the reverse). Tamago's mother was the infamous Kato Ayumu, then Fujiwara Ayumu, who cultivated her mastery of chakra control to form the school of Hair Release. Tamago's pride in her mother's ingenuity was rivaled only by her own ambition; her chakra control, fine-tuned like her Ayumu's, allowed Tamago to grow in proficiency with medical ninjutsu - an invaluable asset for a clan where the healing arts could be so erratic.

Sometime during Tamago's adolescence, clan politics and the growing population of the Fujiwara caused the main branch to split into three parts: the Fujiwara, the Ito, and the Kato. Her mother allied herself with the Kato branch, but Tamago (having reached the Fujiwara's observed age of majority) consigned herself to the main branch, dedicating her services as a medic-nin to research and scientific exploration.

In an effort to increase the Fujiwara clan's success in feudal skirmishes, Tamago began researching the benefits of sensor-types in battle. Believing that the addition of sensors would be to the greatest advantage of the clan, Tamago obsessed over compiling data on chakra perception and sensor bloodlines. Due to the Fujiwara clan's chronicled disadvantage in chakra capacity, Tamago concluded that the most effective option would be to artificially expand the natural range of a ninja's chakra-sensing capabilities, using sealing techniques as a proxy. Her initial pitches were refused by the acting Clan Head for their potential danger to the wearers; the Fujiwara were also famous for their high output of chakra path mutations, so the procedure was considered to great a risk.

Undeterred, Tamago decided to take matters into her own hands. Using confidential clan records, she identified descendants of the Fujiwara far enough removed to have joined or grown up in separate clans or countries. Through these distant members, Tamago tracked the family trees of their sworn Countries' sensor-nin and chose the most likely candidates for her "program"; these individuals later came to be known as the Black Egg 10 through both her study notes and through the mission reports of tracking teams. These candidates, all in their first three years of the academy, were spirited away and taken hostage in a covert base in the Land of Snow.

The Black Egg Affair
Tamago's infamy springs from her involvement in the Black Egg Affair, which happened around the time of the Withdrawal of the Fourth Branch.

Tamago branded the aforementioned 10 abductees with a reverse-engineered Curse Seal designed to expand the victim's chakra pathways and increase chakra sensitivity. However, in order to prevent herself from being detected, Tamago had designed the seals with a closed loop of activation chakra that fed off the host's own reserves. The pattern she had used left the seals highly unstable, resulting in massive trauma to her subjects' chakra paths and a hypersensitive perception factor. The youngest of the 10 died immediately upon receiving the seal and another member followed shortly after, within ten minutes of people branded. Three more suffered severe cerebral trauma resulting in epilepsy.

Tamago was convicted of the unauthorized experimentation and Sealing of ten shinobi academy students without consent, two of which did not survive the process. She was also charged with illegal experimentation, medical malpractice, and the Fujiwara clan's personal charge of "Inhumanity". The last of these charges resulted in her exile from the clan; Tamago was stripped of all rights to her surname, branded on both cheeks, and had her chakra signature removed from the Clan wards. She was sent away from the compound and ostracized by any of her previous family members she came across.

Withdrawal of the Fourth Branch
The Fujiwara were deeply affected by Tamago's actions. In respect and remorse for the atrocity she committed, the original clan emblem of the Fujiwara - a lavender wisteria tree on a dark pinkish background - was replaced by what they colloquially called "the Sensor's Eye." In addition to the shift of the clan's symbol, a sizable portion of the Fujiwara ceded from the tertiary Kato branch to form the Sato. They dedicated their chapter of the clan to defense and military assistance, involving themselves in many missions for the retrieval, rehabilitation, and comfort of Tamago's victims, soon extended their hand to any of their allied countries that required their help.
