Various times, when Zoro is fighting, his scabbards just disappear mid fight. Especially when it is convenient, because he is doing motions that require a lot of flexibility and what not. So, I imagine it is just easier to help with the battle to act like his scabbards do not exist but is there a good reason for this that I am missing?
I have been surprised by the answers to weird questions I have had about anime on the internet so I want to see if someone can give me a rational explanation for this. Thanks!
