Koyoharu Gotouge's Demon Slayer: Kimetsu no Yaiba continues to be one of the most popular action franchises today, and the creator of Fruits Basket honored its main hero with a slick sketch. The last year has seen a huge boon for the Demon Slayer: Kimetsu no Yaiba franchise as a whole thanks to the massive popularity of the anime. Not only has the anime driven sales of the manga to new heights as fans read to see what's next for Tanjiro and the others, but the manga continues to break records all on its own.
