Over the weekend, Demon Slayer: Infinity Castle broke all kinds of records both here and around the world, and it doesn’t look like the hype is going to die down any time soon.

If your kids are fans of the manga or anime and haven’t stopped talking about the new movie, there’s a good chance they may be wanting to rep their favorite character this Halloween.

With that said, we rounded up a few top-rated Demon Slayer costumes for kids that you can snag on Amazon right now.
