Sōryūha



Soryuha (only in movies and anime) also called Dragon Strike in the english dub, is Tokijin's most powerful attack it calls forth a powerful burst of yoki which takes the form of a lightning like discharge. As Sesshomaru grows more powerful with the Tokijin the more the attack comes to full form, i.e. in the beginning Soryuha looked like stokes of lightning, but as the attack improved it became  a powerful dragon-like energy wave.
