Sakamoto's daily wallpaper features a Japanese shonen manga style, with strong, bold lines and exaggerated muscle depiction. The dominant colors are bright yellow and vivid green, paired with a pure white background, creating a striking visual impact. The white-haired, round-glasses-wearing, chubby uncle Sakamoto Taro is wearing a convenience store apron and holding a gun, while the blond teenager Shin shoots stylishly from the back, with shell casings flying around.
