Create an image highlighting the name "Kau ã. " The image should have a background in shades of blue and black, creating a dynamic and attractive look. Add elements inspired by the character Tanjiro Kamado from Demon Slayer, details that reference the character, but without including Tanjiro himself in the image. Remember that the only word that should appear is the name "Kau ã, " in a stylized font that matches the chosen theme and colors
