Stu Levy, founder and chief executive of TOKYOPOP, an American distributor and publisher of anime and manga, loves the way “Demon Slayer” brought together Japanese folklore “with a modern hipness.”

Haganezuka, the creator of Tanjiro’s original sword, claimed that this new sword was made from a stronger material than regular Nichirin swords. Moreover, the manga also implied that the sword was owned by Yoriichi Tsugikuni, the first and strongest demon slayer. However, thanks to Tanjiro’s habit of getting his sword broken, even this legendary sword broke in an important part of the story towards the end.
