WHOOO
Well there's currently one person who use that type of sword and is actively trying to help in that location - Hyo
Was that a sword???
It looked like that for me, but than again we will see it in the next chapter for sure
but it is said that only vital instrument works on him n she doesnt seem to have one tho
We don't really know tho, since we have yet to see her using her blade outside of Zanka flashback, vital instruments are the most precious object for the person who use them, so it's not out of the option, I know I can be mistaken, but I'm also can be right ╮(￣▽￣)╭
Come on we all know who did that XD
