This cute granny from our fanart Demon Slayer Hotaru Haganezuka cursor pack is a supporting character of the anime series about demon killers. Even though he looks like a grandma, it is a Hyottoko mask - a wooden festival mask similar to Sakonji Urokodaki. Hotaru Haganezuka is a swordsmith affiliated with the Demon Slayer Corps, a rather passionate individual who seems to show very little care about anything besides the swords he creates.
