Byakkoshinken

Byakkoshinken (white-tiger true-sword), known as Byakko for short, is an enchanted talking saber Grandmaster Yufang placed within a stone until the one chosen to wield it arrives. That day occured when Kou Hoshinsei removed the weapon from its resting place.

Byakko offered to help Kou as KibaRanger, voicing-over for him upon his deput as KibaRanger and co-piloting Mythical Chi Beast Won Tiger. He could also control Kou's body while fighting as KibaRanger.
