Bunraku was once an art form for puppet entertainment purposes, but now, they are sentient, made of steel, and powered by azure oil to walk the soil at its own will. They were one of the most revolutionary inventions of the Tekkanese industrial era, as a single gallon of oil can bring the bunraku to life. While these metal men can't speak, they are mysteriously intelligent and independent. They are also adjusted to work among the Tatsu Samurai and hunt down the ones who aren't staying in line. Bunrakus have a motive, and it's unknown what that motivation is, but their eerie presence leaves the people of Tatsu intimated.
