-EDIT- altered the colours a bit to make it match various art on here better.
My interpretation of the new Pokemon, Hitotsuki. It's a Ghost and Steel type, and it just seemed so badass on the screenshots O: Hitotsuki can unsheathe itself using the ribbon-like hand on its hilt and hold the sheathe. It appears to look like a normal blade without the sheathe, but I will wait until there's better screenies of the blade before I make an unsheathed sprite. These colours aren't official, and are merely a guess (the best screenie I found had a blue tint to it).
