Bakuryūha

Bakuryuha(爆流破 Explosive Wave, Dub. Backlash Wave) is the ougi or ultimate attack of the Tessaiga. The technique can only be used by someone who has mastered the Kaze no Kizu the base technique of the Tessaiga. When a opponent with strong yoki(demonic energy) unleashes a attack the Tessaiga can use the Wind Scar to engulf the enemy's attack in a twister and reverses it back on them, with the add power of the Wind Scar.

InuYasha learned and mastered the technique when he battled Ryukotsusei. He used the Bakuryuha without knowledge of the technique, something Totosai the creater of the Tessaiga said was impossible. The user must have strong enough yoki to over power his enemy's oe else the technique cannot be used.

When the Bakuryuha is unleashed it fires several twisters filled with the Kaze no Kizu and the yoki of the enemy at an enemy and destroy cuts through their body leaving almost no remains behind.
