Attack Of Giant Frogs

Elise and I reach the location where the shout is, it's Sakura Ai who gave the alert, I climbed the wall and there's a lot of giant frogs outside the wall, those frogs are bigger than the one we fight the first day, this frogs as a red colored skin and black eyes, with big muscles in their legs. Fire magic is the most effective spell on giant frogs, but the magic will not reach them, the frogs are about seventy feet away form the wall, so the magic will not reach them. I need a long range weapon that can combine with the magic, I looked around my classmates maybe I can think of something that can eliminate the frogs with their magic. Wait, it doesn't have to be a long range weapon, then a brilliant idea came to me, it's so good I laughed, Hirumi Saya!, Bella White!, come here I need you to do something for me!, Bella and Saya are helping with the cooking, but luckily I got their attention, they run towards me and ask me if what's up, ' How many swords can you copy?, she said that she can control a dozens of sword, ' Bella I want you to focus your fire magic on the swords, covered the swords with fire but don't destroy them, can you do it?', with no hesitation she answered that she can do it.
