Takemikazuchi Hachishiki or Shinobu (偲ぶ) is a sword that was forged by the phoenixes and is one of their greatest treasures.
Takemikazuchi Hachishiki started as just a sword forged using the phoenix's own fire. Being around them, the sword began passively absorbing Nature Energy. After a while, it gained a sentient form. The phoenixes named this form Shinobu as it had no gender.
The blade was one of the treasures taken when the Uchiha Clan drove the phoenixes from their home to the Forest of Resplendent Flames. Madara Uchiha would return the blade as a gesture of trust after it was wielded by his sister Fūsha Uchiha for a few years. The sword, having been wielded by a woman, began changing the sentient form. Shinobu found itself beginning to gain traits of a female human.
In both the canon as well as the Naruto: New Moon storyline, the only third wielder of the blade is Nasuka Uchiha (New Moon). Now under a third female wielder, Shinobu successfully turned into the appearance of a young girl with blonde hair and red eyes.
The blade has been passively absorbing Nature Energy ever since it was forged, many millennia ago. It was because of this that the blade eventually gained its own personality and a sentient form. That form was named Shinobu. At first, it was gender neutral. It did not have any one gender. Another three hundred years would pass before the first humans made contact with the phoenixes.
In the hands of Fūsha Uchiha, the blade got the first tastes of blood, however, little was shed with the blade. With the guidance of Shinobu, the Uchiha would learn the secrets of the Sage Mode of the phoenixes. In exchange for tutoring the Uchiha, the blade received some feedback, starting the process of changing itself into a female. This was never completed as since Fūsha returned the blade out of trust.
It was in the hands of her daughter, Shizuoka Uchiha when the blade would taste much blood. Shizuoka Uchiha lived through the carnage that was the Second and Third Shinobi World Wars. She was a force to be reckoned with on the battlefield with the power of the sword. Silver flames cutting through enemy ranks were just one of the terrors brought about by Shizuoka Uchiha. Again, like in her mother's case, the blade would further its metamorphosis into a young female girl. Shinobu would identify herself as female from that point on.
The sword can also bestow upon its wielders Phoenix Release although so far all of its previous wielders have already been able to use it.
