Susamaru, also known as the Temari Demon was a Demon that aspired to join Muzan Kibutsuji's Twelve Kizuki. Susamaru is a pale-skinned woman with bright hazel eyes with cat-like pupils and black hair with orange-colored ends. She has bangs over her forehead and the ends of her hair appear similar to paintbrushes. Susamaru wears a pair of long silver earrings and an orange kimono that matches her hair. She wears a black kimono on top but takes them both off when she enters battle, revealing a small sash that covers her chest. Although she normally has an average build, when fighting seriously, her arms become noticeably more muscular. She can also grow two new pairs of arms as well. Susamaru is almost always smiling and enjoys a challenge. Her pet phrase is "what fun this is" and she will repeat this constantly if engaged in bouts she deems amusing. Her immaturity is a stark contrast to Yahaba's seriousness.
