See Tachi: Enpi for the translation of "Tachi:"
The Japanese characters for "Gekko" mean "Moon Light", but can be loosely translated into "lunar light" (Getsu "moon" + ko "light" = Gekko) This makes sense given the full moon featured in the weaponskill's animation. 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.".
