I just found out the levi has a transparent blue ribbon circling the blade in a figure eight. However, this aura does not appear to be visible at all times.

So far I've found that it's only visible on ice and shock stages. I assume this is unintentional. I know it's a very minor bug and therefore low priority, but it'd be nice if the devs could look into this. It's a little disappointing to me when a weapon I like using can't be displayed in its full glory, the way it was intended to be displayed.
