Pyrrha and Black get away with it because of a magnetic sheath, which means they don't have to draw their weapon from the scabbard, which stays there. In Blakes case, she uses the scabbard as a melee weapon as well, and has gotten used to drawing her blade from there enough to get away with drawing the blade but not the sheath in a pinch. Pyrrha basically uses her semblance to get the blade and shield to her hands, which negates problems drawing blades over the shoulders bring with it.

Sage...probably has a magnetic sheath as well, since he doesnt actually have a proper sheath for his sword. This allows him to easily pull the blade away from his back without having to get it clear of a holster or sheath over his shoulder.

If you were to use a magnetic clasp on the OC's back, which means the entire weapon including actual sheath comes away when they draw it, then you could get away with it, as it removes the need for over-the-shoulder draws, which are very difficult in practise. The problem with that is that if they just want the short sword, it would be slightly difficult to clear it from the sheath, as when drawing a weapon from your back the sheath does not move, which means you have to stretch your arm up high enough to clear the entire blade in a straight up motion before being able to bring it down to a ready position.
