Sword of Damocles

The Sword of Damocles is a symbol of danger as it houses incredible powers. It is the symbol of the Kings. When the sword starts to crumble and decay, it's considered dangerous and is a sign that the owner has reached the "on the verge of outburst" state. In other words, the 'sword' appears and begins to decay whenever any of the Kings begin to fight seriously.

The swords each have a unique design and are distinguished from each other by the Aura that pulsates around them. For example, Suoh's can be identified by the Red Aura, while Munakata's sword has Blue Aura pulsating around it.
