Kaze no Kizu

is a special attack technique featured in the manga and anime series InuYasha. The technique is the base attack of the phantom sword Tetsusaiga, currently wielded by Inuyasha.

This attack is accomplished by finding the rift, or scar, between the powerful yokai auras of Tetsusaiga's wielder and the opposing demon. Once the Wind Scar is found, the wielder of Tetsusaiga can swing the sword into the rift to release a powerful energy wave that has the power to kill 100 yokai in one strike.

Inuyasha used the Kaze no Kizu for the first time unintentionally when he was trying to save Miroku so he wouldn't use his Wind Tunnel. When the wielder becomes proficient enough, the Kaze no Kizu surrounds Tetsusaiga and can be used at will.

Built upon this attack is the more powerful attack called Bakuryuha. Inuyasha first used Bakuryuha fighting Ryūkotsusei, the demon that Inuyasha's father sealed in the Black Pearl. Inuyasha accidently used Bakuryuha trying to used Kaze no Kizu. Defeating Ryukotsusei resulted in mastering Kaze no Kizu and Bakuyuha, thus making Kaze no Kizu usable even without considering the yokai aura.

The Kaze no Kizu can only be performed if one is wielding the Tetsusaiga. The only exceptions are when someone steals Tetsusaiga's demonic power, and puts it into their own sword. Such as with Kanna's mirror demon, and the sword, Dakki.
