Takemikazuchi Hachishiki or Arisa (愛里沙) is a sword of unparalleled construction forged by the progenitor of the Abura Clan, Abura Uchiha, using her masterful finesse over senjutsu and Nature Energy alongside her expertise in Phoenix Sage Mode. It is one of the Treasured Tools of Nature's Omniscience.
Takemikazuchi Hachishiki was forged by Abura Uchiha alongside the other six Treasured Tools of Nature's Omniscience. She had created them with the help of the phoenixes of Aokigahara Rainforest, imbuing the forging process with copious amounts of Nature Energy. After finishing the creation of the sword alongside the other tools, Abura brought all seven tools back to Takigakure where due to its awesome power, it was revered to be the family heirlooms of the Abura Clan; Abura also insisted that the tools, including Takemikazuchi Hachishiki, to only be wielded by her descendants and relatives, that is, the Abura Clan and Uchiha Clan. Taking that message to heart, the tools have only been used by either an Abura or an Uchiha, however, Abura's descendants also misunderstood her words, thinking that she had also meant that the next leader of the Abura Clan must be able to use at least four of the Treasured Tools; Takemikazuchi Hachishiki is the most lenient of all of the tools and as such, has had the most wielders.
