This is the largest and most famous clan from the village of Takumi, and is well known for their creativity when it comes to making weapons. It is rumored that the weapon creator Seimei is either descended from or the founder of this clan, not to mention that they also may be responsible for the four weapons. It is also known that they have high expectations for their members, and those that go against the clan's wishes are exiled/banished from the clan. This is what happened to Kashikoi Monodukuri after she wounded her parents and left the clan following her eavesdropping of the clan's plan.
