Katanagatari novel volume 3 was written by Nisioisin.

Swordless “swordsman” Schichika and self-described “schemer” Togame are on a  quest to obtain twelve peculiar masterpice blades. Pitting the former against his sister, who has acquired one of the legendary weapons, and the latter against a rival at court, Princess Negative, this paperback edition, featuring beautiful interior art and copious bilingual footnotes, is the third of a quartet collecting a best-selling series from the former homeland of samurais and ninjas.
