Okay. Youkai means demon. Hanyou means Half-demon. Inu means dog. Yasha means spirit in Buddist terms. The Kaze no Kizu (lit. Wound of the Wind) or Wind Scar in the english version is the special move of the Tessaiga. The Wind Scar is a move that can slay 100 enemies with a single swing. At first Inuyasha performed this move by accident but later learned that his demonic aura has to collide with his opponent's, the two demonic energies colliding creates a fissure called the Wind Scar and the Tessaiga is to cut through it. But Inuyasha can later use it whenever he pleases after defeating Ryukotsusei and learns the Bakuryūha.
