Yuruginai

Yuruginai, the Celestial Sword of the Crab, is probably the least used Celestial Sword, despite being carried by each Clan Champion since it was given. Hida O-Ushi, its first wielder, preferred her dai tsuchi instead. Hida Kuroda used it briefly, but it was broken and taken to be reforged for Hida Kuon when Kuroda fell to Kyofu. Kuon has not wielded it, as he intends use it to strike down his corrupted brother.

Yuruginai is thicker than most of the Celestial Swords, and its handle and tsuba are intricately covered. The blade's new saya is decorated with jade inlays, enchanted to never tarnish. The blade is incredibly strong since its repair, and more than one (including a Kaiu blade) has been shattered against its strength. Kaiu Tasuku, the master smith who fixed the blade, promised that if the blade ever breaks again he would break his hammer and become a poet.
