Hey the vn is still early days so i have no doubt that it'll get sorted as for weapons being too big you could just bloodborne them. Bloodborne's trick weapons can be used small or folded out to be bigger a bardiche could have a simple metal holsteer that just contains the blade and a small handle with the ferals being able to extend it to full length with a simple button press. Its your vn world so you could explain it however you want. collapsible weapons are somthing thats logistically possible and a rather simple explanation that you wouldnt need to explain too hard so its a option but in the end its up to you.
Also just because its text and the way i type can come off as abrasive. I actually do like what you've done so far the critique about the combat is just because that stands out most to me because i overanalyze things like that (i play far too many strategy games) so im more hyper aware of it. However don't take my comment too seriously? too heart? I'm no sure how to put it because both of them are wrong, i guess don't over think it your vn is still very early most of the writing is judas back story gil's story and great job of world building. So you don't need to worry so much you can always go back later to polish it up if you aren't satisfied with it. The combat and other characters have only barely been touched on and you've got all the time in the world. I've no doubt as the story continues and everything fleshes out more you'll do a great job, you've already proven that you've got a verry good quallity of writing. So just keep on keeping on and dont worry so much.
