Ea

Ea, also referred to as the Third Treasure of the Old World, is a cavalry spear wielded by the Missing-nin Haigo Hyūga, often times alongside the halberd, Setchi.

The shaft of the weapon was purple while the bottom and blade were a bronze-coloured steel. The blade was decorated slightly extending outward like mouth only to come back into a point for the blade itself. Embedded in the blade was a small blue gem of unknown value. The bottom of the spear held a second, much shorter blade of simple design. Both blades carried signs of aging, with numerous scratches coating the metal and small chips being very clearly missing from the weapon.

Ea was the first weapon Haigo wielded after losing Kyohaku Sasumono during the Chūnin Exams. She found it deep within an old temple that she had decided to search during her travels around the world. It quickly became a favoured weapon of hers as she performed constant maintenance on the old weapon, bringing it up to a capable fighting standard. Ea, and later, Setchi, would become the core of Haigo's own style of Kenjutsu in later life.

Ea carried the ability to absorb Water, and, Wind, through the use of chakra, which could then be expelled in powerful waves.
