Kyo's forge, though named after her, is not explicitly hers. While she does use it the most, it's also overseen by her personal attendant... Yoshi, identical triplet of Toshi and Hoshi. He's often found keeping the forge warm and sharpening the tools of those who need it. Kyo is also there, but she mainly works on crafting building components or sharpening the weapons of the other samurai.
