Demon sword Kokorowatari: Koyomi describes it as a sword that surpasses human understanding, A sword which can cut through any and all oddities, it is said to be an unstoppable weapon in front of anything supernatural but useless in front of anything normal. A single scratch from it made an oddity like Black Hanekawa scream in intense pain and terror, made her unable to move and caused her horrible mutation (Though Shinobu later saved her). The Kokorowatari (translates to "Heart Span"), also called the Kaii Killer, is created specifically to kill kaii (supernatural beings, such as ghosts, vampires, etc.). The sword originally belonged to a samurai 400 years prior to the start of the series. The original Kokorowatari has been destroyed, but Shinobu can replicate it using her matter creation power. "The demon sword "Kokorowatari", the Kaii Killer -- as the name implied, was a blade for killing the kaii. Just the kaii. A deadly weapon for killing only the kaii. To put it the other way around, it was a deadly weapon that couldn't kill humans -- in fact, it was not just limited to humans. The Kaii Killer couldn't slice any lifeforms or objects that weren't kaii. An unparalleled sword in front of a kaii, but if you weren't in front of one it was equivalent to a blunt blade. Someone could say it was even worse than a blunt sword -- it didn't even physically collide with what was not a kaii. Just like an incorporeal ghost, it slipped through, it passed by. Although strictly speaking this Kokorowatari the vampire little girl owned was a replica, a fake, we should say that this fake possessed such characteristics as a result of being created with vampire fantastic superpowers in a wild idea, it seemed the genuine Kaii Killer was something like Ishikawa Goemon's Zantetsuken, which could cut everything in this world but the konjac."
