The Kimetsu no Yaiba: Demon Slayer Complete Box Set is a collection of all 23 volumes of the manga series written by Koyoharu Gotouge. The set is in English and features the original artwork from the series. The manga is part of the Demon Slayer: Kimetsu no Yaiba universe and follows the story of a young boy named Tanjiro as he fights demons and tries to save his sister. The set is a must-have for fans of the series and collectors of manga and Asian comics. I’m an honest seller and I don’t do returns unless there was a material misrepresentation on the listing which is covered under eBay’s guarantee.
