See Tachi: Enpi for the translation of "Tachi:"

This weaponskill's original name in the Japanese version is:

太刀・月光 (Hachi no Tachi: Gekkou)

"The Eighth Style of the Tachi: 'Moonlight'."

The kanji are 月 (Getsu): "Moon", and 光 (Kou): "Light". This is reflected in the weaponskill itself, as the animation illustrates a brightly glowing moon. The moon also has a thin, lime-green, outer circle with Hebrew letters, which translate to, "In the beginning, God created the heavens and the earth.".
