Setchi

Setchi, also known as the Fifth Treasure of the Old World, was a halberd, or pole-axe, wielded by the Missing-nin, Haigo Hyūga, often times alongside, Ea.

The shaft of the halberd was an assortment of blue shades mixed up in a pattern to mimic the look of water. Its blade, centre grip, and bottom, were all a steely-grey in colour. Marking the blade are a couple of cosmetic designs and the bottom of the halberd is identified by a rising spiral of metal.

Haigo recieved the weapon in place of standard payment after she completed a mission on behalf of the daimyo of the Land of Keys. Haigo was quick to integrate the weapon into her fighting style, admiring the craftmanship too much to get rid of it, and too attached to Ea to replace it. Setchi, and Ea, would go on to become the core of Haigo's own style of Kenjutsu in later life.

Setchi was capable of absorbing Water through the use of chakra which could later be expelled as powerful liquid-waves. It carried an ability similar to the Kubikiribōchō in that it could repair itself, however while the Kubikiribōchō did this through blood, Setchi did this by absorbing the Chakra of its wielder and molding the earth (Which it needed to be in contact with) into replacements for any missing part.
