Kurodzuru ( lit. Black Fish ) is a sword belonging to Hoshin Seikijinshuu. Kurodzuru is Hoshin's favourite sword, and also the one he believes most perfectly replicates the spirit of a swordsman. He came across Kurodzuru at a ruined temple when he was on a mission, and fell in love with it, deciding to make it his own. Kurodzuru is a pure black sword, which possesses unparallelled slicing power. It is capable of ripping through stone or steel, and can go head-to-head with even the Kusanagi without breaking. However, Kurodzuru possesses no abilities and is just a normal katana with unusual sharpness and durability.
