I integrated several Japanese terms into my fics for several reasons. The English terms in most cases do not do them justice. "Sankon Tessou" sounds way less cheesy than "Iron Reaver, Soul Stealer!". There are also varrying disagreements on accuracy, even within VIZ. Compare the Inuyasha manga to the anime- "Sankon Tessou" apparently means "Iron Reaver, Soul Stealer" if the picture moves and "Claws of Steel" if the picture is stationary. Anyways, I these are the rough translations I have infered
