I've Got It
As someone else in the comments said, I don't think it hurts to have videos that somewhat stray away from your youtube 'niche,' I think it's totally fine. Even if you have a curveball of a video every now and then that doesn't have much of a relevance to the rest of your videos I don't think that's a bad thing haha.
If the video is benefiting your channel over all, then definitely keep it!
