How would a long sword help? It would be heavier and more unwieldy to use, and it doesn't seem like they are having trouble with the short swords, the short swords help them move quicker and stay agile. The only real issue they have is just that their weapons are seemingly weak and break easily (so need a lot of extras), and that's not something a longer sword would fix.Oh that's why kids, why we must call pest control. I don't get it why they fight with just short sword in the first place. Probably for stupid tension.
