This is the PROPLICA Nichirin Blade of Kyojuro Rengoku from the TV anime "Demon Slayer: Kimetsu no Yaiba." It's an approximately 1/1 scale official 3D recreation. It includes over 60 sounds, such as Kyojuro Rengoku's famous lines, Flame Breathing techniques, and sound effects, as well as Tanjiro's voice. Furthermore, it includes the movie theme song "Homura" (approx. 55 seconds) as background music, which can be played simultaneously with the lines. It was opened for photography, but it's in like-new condition.
