Kusanagi

The Kusanagi no Tsurugi, or the Kusanagi Blade as it is more commonly called is a sword of mysterious origin. It is one the Tenno of the Genji Sub-sector's regalia, symbolising courage.

History
The earliest known record of the Kusanagi's existence is the Genjijiki, making that record's availability limited. Errant Kami Susanoo discovered the sword inside the stomach of the Yamatanoorochi, a monster he killed. Naming the sword Amenomurakumonotsurugi, he brought it back to the Realm of the Kami with him as a pease offering to his sister, Amaterasu. The sword left the realm when Ninigi traveled to Nara and was passed on to Tenno Jimmu, his descendant and used it against a daemonic bear that had the ability to sedate those around it.

The sword saw use by Shinno Yamatotakeru in his quest to quell a short-lived rebellion in the Genji Sub-sector, given it by his aunt. When the warrior was fighting the rebels he discovered how the sword controlled the wind. Using the unique ability he was able to escape number of situations where he would have died. The triumphant Shinno named the sword Kusanagi no Tsurugi.

Presently the sword is kept at the Atsuta shrine in Aichi, kept under close security. Although it is used as a regalia for crowning new Tenno, it is hidden in a box.

Properties
The sword is widely believed to be of mystic origin as no design of swords come close to it. The sword as described by a priest who claimed to have saw it: "was about eighty centimetres long, shaped like a shoubu plant, metal white with texture like marble" prior to his untimely death believed to be caused by the power of the sword.

Parallel Kusanagi
Kotaishi Tydridalamor wields the Kusanagi of his timeline to battle. His Kusanagi fits almost all description, but had turned into a rust-like colour.

The Parallel Kusanagi was almost stolen by the Eldar but was stopped by the Kotaisha and Lord General Castor. Tydridalamor at this time also discovered that he can enhance his Bloof Elf magics with the sword.

After research, the sword is discovered to have been forged by the Eldar God Vaul, and thought to have been lost after the War in Heaven. The sword was eventually purified to it's former glory with the assistance of Farseer Eldrad Ulthran and Lofn.

Goldfang
The Goldfang is another sword identical to the Kusanagi. It however is covered in wraps to enhance grip. Ilithdora Khan uses the sword in conjunction to her ice magics, after inhereting it from the Chinggid Khagan. The sword is also bronze in colour.
