If it's a male sword, at least it will stay a sword and not turn into a waifu making the sword part moot. Will be perverted though, it's just a given trait of all male swords.
@randomname Most male MC mangas have a talking female weapon (when the weapons talks cause even the weapon needs to be a part of the harem) so I would be interested in how this goes.
Since the sword is intelligent it may have its own preferred pronoun or not even care either way. It could also change depending on its user too. There's so many ways this can go.
