Creating an unkown sword slash effect

After scrolling twitter ages ago I came across an interesting slash effect that I have no idea how to reproduce. I’m referring to the blue / white slashes when you swing your weapon. See a video of it: Of course one might automatically assume a trail is the way to go here, but after trying (and failing) the best thing I could create wasn’t at all looking like this video. After closer inspection, I realized that it may not be a trail. At 0.25 speed you can see the effect go past …

How would I go about making this effect?

As the topic title asks, I’m wondering how I would make this effect, for a while now I’ve seen it being used more commonly. To be less vague the effect I’m looking at is the moon like shape. Not sure if it’s an asset that’s out there for free or an invisible mesh that’s wrapped in a texture/decal.
