Episode 97 of Inuyasha: Kirara, Come Home! doesn't actually say when InuYasha practices the Wind Scar on Kirara, but from looking at the flashback when Shippo points out various things Inuyasha has done to Kirara; this leads me to believe that this may have happened in Episode 36 of InuYasha: "Kagome Kidnapped by Koga, The Wolf-Demon".
Sesshomaru demonstrated it to Inuyasha and during a battle when Inuyasha was blinded he learned to use his other senses beside his eyes and "feels" the two wind "paths" blending together creating a wind scar, he strikes it with his Tenseiga and bam the magic happens. :)
That would be Episode 67: "The Howling Wind of Betrayal" where Kagura discovers that Inuyasha will change into a human during the new moon, but decides to keep it to herself when Naraku, who is undergoing a horrifying transformation of his own, threatens her life again.
when Inuyasha first uses the wind scar successfully on Sesshomaru, Sesshomaru is warped by tensaiga to a forest where he meets Rin for the first time.

You should be more specific -- he gets hurt a lot. But grievously hurt? Well, eppy 19, Sesshomaru shoves his hand through Inuyasha's chest: Go Home to your own time, kagome! The Deadly Trap of Kagura, The Wind Sorceress: Koga hurts inuyasha, and he passes out. In The Wind Scar Fails, Inuyasha gets his wind scar thrust back at him by Kanna and Kagura. The one right after it, Tetsusaiga Breaks, is good, too -- he's already hurt and fights a powerful incarnation of Naraku. There's a spray of Inuyasha's blood in that one. *devilish grin* And he turns into a demon! Inuyasha's Soul, Devoured, and The Demon's True Nature are pretty good; he gets trapped in a poisonous cocoon, with poison already in his system. And Sesshomaru gets in a few good whacks. Fateful Night in Togenkyo Parts 1 and 2 have a black-haired Inuyasha getting hurt. The ones in between here I don't know so well. But I don't think they're as juicy as some of the ones I am listing. In Vanished in a River of Flames, it seems for awhile like he dies... but that's brief and he's not actually hurt. In Divine Malice of the Saint, and Fare Thee Well - Jakotsu's Requiem, he fights Jakotsu as a mortal. That's pretty bloody. In Destroy Naraku w/ Adamant Barrage, Inuyasha fights Hosenki and gets cut up with adamant. In Possessed by a Parasite: Shippo, Our Worst Enemy, Inuyasha gets a faceful of set beads, and he feels terrible. That one is not very noteworthy, but I included it anyway. In the final episode, a black jewel shard takes him over. He's not actually injured there, but if you're like me, you like the eppies where he turns into a demon. That oughta do it. Those are the ones in which Inuyasha gets really hurt.

Inuyasha. Obviously. Sure Jacob can turn into a wolf, but inuyasha has the tensaiga. Plus around episode 35 inuyasha masters the wind scar- giving him the ability to kill with one blow. Jacob has claws. Inuyasha wins. Every time.
he uses the windscar as a power in his sword the demonic power between him and his enemy create a scar in the wind being the winscar inuyasha strikes this scar creating a huge wave of power
i'm sure inuyasha would win because by the time the scouts transfrom the would be wind scar dust. the wind scar is strong than anything the can pull out. Plus it then the back lash wave to send it back at them. Not to metion the other member of inuyasha team kogome sango shippo and miruku.
It wasn't in an episode, it was in the first movie.
That would be Episode 67: "The Howling Wind of Betrayal" where Kagura discovers that Inuyasha will change into a human during the new moon, but decides to keep it to herself when Naraku, who is undergoing a horrifying transformation of his own, threatens her life again.
It can do Wind Scar, Backlash Wave, The Barrier-Breaking, Dragon-Scaled, Black Tetsusaiga, and Diamond/Adamant. So 6.
when Inuyasha first uses the wind scar successfully on Sesshomaru, Sesshomaru is warped by tensaiga to a forest where he meets Rin for the first time.

Ah, I have that game. Okay, in order to defeat sara in inuyasha and the divine jewel, you have to try have a little bit level up with everyone, once you get there and have a battle with Sara, first defeat sara using wind scar and use the blackwash wind and try to defeat sara and then you can defeat all the demon once sara is gone in the battle.

I believe she would learn how to do it in the season 20 episode: 'Whistling In the Wind'.
