It's incorrect japanese, I know. I only know a few words anyway. Mizu is water in japanese and I took mune from the word masamune which means big sword or something of the sort in japanese. and there you have it. Water-sword. it's an elemental sword and Kayli weilds its power. The belt and necklace also have power. It was passed down to her from her grandmother. she NEVER takes that necklace off.
