Why young kids know Demon Slayer
The characters are everywhere: toys, costumes, school supplies, and short clips online. Many young kids know the sword moves and the names of the "breathing" techniques without having watched the show.

In Demon Slayer, every problem is a fight. Some kids bring the sword moves to the playground, with sticks.
