Kokorowatari

==Summary==
Kokorowatari is a sword in the series; Monogatari.
The longer companion sword to Yumewatari, passed down to Seishirou Shishirui from his ancestors. It can cut through any supernatural being and kill them with a single scratch, including ghosts and selectively tangible beings. It is useless otherwise, as it simply phases through targets without dealing any harm to them.
After the original was lost 400 years ago, Seishirou used his own flesh and blood to make a replica, which he passed onto Shinobu Oshino, who was then capable of creating additional replicas for her own use using her matter creation powers. More recently, Izuko Gaen forged the sword, along with Yumewatari, out of Sehishirou's corpse.
