Well, he tried to get out of this. Unhappy about the prospect, he picked up a blade and held it with both hands. It was heavy, but nothing Alex wasn't used to handling. He examined it carefully. The blade was a bit rushed, but he did have to make a lot of them. Still, it was a relatively easy job, if time consuming. He held the blade in front of him in a basic grip that felt alright. Of course, he wasn't ready for this. The most combat he had seen lately was that one small scuffle with that demon thing.
He took a deep breath and charged forward, swinging the sword in a wide arc from his left shoulder diagonally downwards. As he swing it, the blade itself turned red as it began to heat up before setting on fire. The flames, while hot, didn't melt the blade, though it glowed with heat. The runes inside of it sparked the chemical reaction needed for fire and contained it in a flickering field around the blade.
All Alex could hope for is that she would dodge, block, or something. He didn't want to hurt her. He didn't want to hurt anyone.
