Cloud Piercer

Introduction
Cloud Piercer was a scared spirit that was worshiped as the Guardian of the Dalmasca people. When the village fell and became ruins the temple was all but lost till Shiranui and her team found it deep in the wetlands. After exploring the temple and discovering the statue something happened and the spirit of the temple fused with her sword.

Appearance
Cloud Piercer is of Unknown Grade katana but after being infused with the spirit of the temple it changes into a large Claymore. The blade is a long, very wide, double-edged form of a longsword. The crossguard consists of two small blue gems at the center of a cats head and two straight ornate arms that resemble a cats body and ending in simplistic version of a cats tail. The sword's handle runs through its guard, continuing on through a gold hollow space at the base of its blade. The handle is almost the same length of the blade itself.

Abilities and Powers
Cloud Piercer has the power to change its form from a katana just by saying its name and spinning the sword around. In this form it can cut through any smoke or fog.
