[@Artymis]Alright sounds good. Did you want two entities, or just one single entity as the Zanpakuto? I know Captain Shunsui has two. My character is going to lean towards a lightning affiliation, or at least that's what I am planning.

It can be either. It depends what you're trying to go for in your zanpakuto. I suppose it should be two, but if you wanted to work something up with one in an interesting twist then you can go for it!
