New Demon Slayer Apparel Arrives: Zenitsu and Kaigaku, Akaza T-Shirts Revealed

New apparel from the anime Demon Slayer: Kimetsu no Yaiba has been announced. The lineup includes the “Zenitsu and Kaigaku T-Shirt,” featuring fellow disciples Zenitsu Agatsuma and Kaigaku as their paths and gazes collide. Also included is the Akaza “Won’t you become a demon too?” T-shirt, designed around the scene in which Akaza delivers the line. Both items are scheduled for release in late July 2026 and are now available for pre-order via the COSPA Online Shop and other retailers. The article also mentions an early September 2026 release window, so the official product page should be checked for the final release date. Product details: “Zenitsu and Kaigaku T-Shirt” comes in sizes S/M/L/XL, color BLACK, priced at 3,300 yen including tax. “Akaza ‘Won’t you become a demon too?’ T-Shirt” comes in sizes S/M/L/XL, color BLACK, priced at 3,300 yen including tax. The shirts use durable and comfortable 5.6-ounce fabric with enough thickness and strength to be worn on their own. The material offers breathability, moisture absorption, and heat retention for comfortable wear across seasons. The fabric uses yarn designed to reduce fuzziness, creating a smooth feel against the skin. A seamless tubular body construction helps prevent twisting after washing and maintains comfort. The ribbed neckline makes the shirt easy to put on and take off, while taped shoulder finishing helps prevent stretching and deformation around the collar. The neck and sleeve openings use double stitching for a sturdy finish intended for long-term wear. Copyright: © Koyoharu Gotouge / SHUEISHA, Aniplex, ufotable.
