Windstorm

A white sword of light slashed through the air, leaving behind only afterimages of light and a burnt smell.

I kept making fancy movements with my sword of light, filling the entire area with afterimages.

I demolished the ruin in front of me into rubble. I then slashed the rubble into dust. After that, I happily put away my bladeless Holy Light sword away in my sleeve.

Yes, that was correct. My sleeve was more than enough to act as my scabbard.

"This sword really only has a sword hilt?" Harloys asked. I nodded with certainty.

My sword didn't have a blade. This wasn't because it was incomplete, but rather because I had designed it without a blade to begin with. This sword of mine was a lightsaber, a design that had never been seen in this one before and which I had plagiarized from my original world.
