So I live in Japan and i was here during the big boom.

Nobody talked about it before the anime. The anime came out JUST
when Covid started here. You know what I saw more than anything during that time? Masks with the characters fabric in them. You could see the main characters masks everywhere. Kids were wearing them during covid. They also had merchandise of it too.pencil cases, all that normal stuff. Plus, the theme song was sooooooo big out here. You couldnt go to a store without hearing it once. It was all over TV and even in arcade music games here.

A combination of right time and place (exciting new thing at the start of a confusing time), heavy marketing push, and an earworm song that played every 30 minutes. I dont know how it was in the US, but i had never seen an anime take off like that so quickly.

Its still around today but it has died off a lot. People are back to their mainstay anime like Conan, Pokemon, and shounen stuff.
