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.

The Kaze no Kizu has been performed by the Inu no Taisho, Inuyasha, and Sesshomaru.
