I have the Demon Slayer special edition manga with the can badges, but only Tanjiro and Rengoku are missing. Also, the hologram ones are from gashapon machines. Demon Slayer Can Badge Hologram Pajama Character 5th Edition: Inosuke Hashibira, Giyu Tomioka Sanemi Shinazugawa Tengen Uzui Gyomei Himejima are from Kura Sushi. Some of them have rust on the back.
