This is a Bandai Demon Slayer Kimetsu no Yaiba DX Nichirin Sword, officially licensed in Japan. It is made of plastic, measures 580mm in size, and is inspired by the TV show Demon Slayer: Kimetsu no Yaiba.  It has 50 dsifferent sounds and japanese phrases from the anime series.  The life-size replica Tanjiro Kamado's Nichirin Sword is here as a Proplica from Bandai Spirits! Tanjiro's blade was created to capture the beauty and feel of a real-life blade using carefully molded plastic. It features fine details, such as a tsuba guard painted in a metallic black for contrast. The sword also plays back more than 50 sounds from the show, ranging from the Demon Slayers theme song to samples of Tanjiro Kamado's dialogue. The samples were selected from Demon Slayers or Fighting Tanjiro Kamado modes, with the opening theme as sung by Lisa. It also includes a special booklet introducing "kata" from the anime.
