Bouishi Kasuga

Bouishi Kasuga is the Ancestral Sword of the Tortoise Clan. It was created when Hantei Muhaki directed Tortoise Clan Champion Kasuga to have a new blade made for himself. Kasuga, formerly of the Agasha family, used his old contacts to obtain high-quality metal and had the finest craftsmen forge a new daisho.

Kasuga presented the blades to Muhaki, who was impressed with their quality and named the katana Kasuga's Eye. Kasuga gave Muhaki the wakizashi in symbol of the Tortoise' complete service to the Emperor. The wakizashi sat next to the Emerald Throne until after the death of Toturi I. It was later claimed by Hantei Naseru, who kept it in his estate. It is not known what happened to the blade after Naseru was made Emperor.

Powers
The katana is one of the finest blades ever forged. It makes its wielder somewhat lighter on his feet and deals greater damage to those who violate the Imperial Law. It can only be drawn by one of Tortoise or Imperial blood.

The wakizashi is of the same quality of the katana, and will only open for Tortoise or Imperial samurai. It has but one power, its bearer may at any time see what the katana's wielder is doing.
