Why This Is the Perfect Time to Catch Up on Demon Slayer
Adapted from Koyoharu Gotouge’s manga and animated by Ufotable, Demon Slayer is now one of the biggest anime franchises of all time, due to its mind-blowing animation, epic fight scenes, and emotional storytelling.
Kazuhiko Torishima, former Weekly Shonen Jump editor of Dragon Ball, once likened the manga to raw coffee beans and stated the anime “roasted and brewed them into something truly special.”
