It is said, that when the transmigrants of Indra and Asura pass away, the original souls emit once more from the corpses, in order to search for those who are worthy of carrying on the tradition. These spirits, contained the chakra of their respective originals, traveling the entire shinobi globe for those who are worthy enough to 'continue the fight'.

Metal Release, the special ability of Sannotto Senju. The act of gathering chakra from the very environment to aid in battle, as well as bits of minerals to garner the appropriate metal. The earth's crust is inhabited by a thorough amount of iron, allowing those who possess this ability to call upon nature to gather the required portion to manifest in war.

When a child is born, who inherits this special ability, otherwise known as a kekkei tota, the child is introduced to this act of 'harvesting'. The offspring's first taste of nature comes from all around the atmosphere, bits of chakra leftovers are pulled through magnetic force to bless the offspring.

Upon the birth of Sayuri Senju, the spirits of Indra and Asura were once again set free from their previous transmigrants. Seeking for their next host, the spirits traveled to Konoha, the village which had produced fine shinobi such as Madara Uchiha, Sasuke Uchiha, and on the other side, Hashirama Senju, and Naruto Uzumaki. The spirits searched far and wide for those who were worthy to bear the respective curses. However, bypassing through the village's hospital, they were brought upon a strong magnetic pull, coming from the womb of Yami Uchiha. The woman pushed with all her might, the child emerging from within her collecting bits of chakra from nearby. The spirits, through concentrating their powers, managed to slip by, after offering their fair share of chakra towards the magnetic force. A bribe in order to be released.

This chakra, as small as it may had been, was collected by the newly born Sayuri Senju, who was in the hands of her father. Only he had known what had occurred that very moment, tears appearing on the hospital floor as Yami Uchiha passed away.
