I should also mention the difference between streaming and downloading. If they have a 4K TV or monitor, maybe they can stream it via legal services. If they're looking for a 4K UHD disc, I can mention that. Also, note that some sites might repackage pirated content as 4K 60fps, but that's not reliable or legal.

Purchase the 4K Blu-ray directly from Funimation or stream via Amazon/Apple TV for optimal quality and legitimacy. Disclaimer: This article promotes ethical viewing practices and does not endorse piracy.

Also, the user might be looking to pirate the movie. Since I'm supposed to avoid aiding in piracy, I need to make that clear. They might not realize the movie is available legally. I should direct them to official sources.

Another angle: maybe the user wants to watch it in native 4K 60fps, which might require hardware that supports HDMI 2.1. I can briefly explain that. Also, check if the movie actually has scenes that use 60fps; perhaps they want smoother animation which could be simulated in 60fps.

Finally, ensure the article is informative, guides them towards legal options, and warns against illegal sources. Make it clear that providing direct links to piracy is against terms of service and potentially illegal in many countries.
