Susamaru

A direct subordinate of Muzan. A demon girl with a bob haircut who speaks in an old-fashioned manner and behaves like a young girl. She claims to be one of the Twelve Kizuki but is merely being deceived by Muzan. She uses the Blood Demon Art "Temari," which allows her to throw or kick temari balls for attacks, as well as replicate them. Her arms and temari balls can increase up to six each due to her Blood Demon Art, with immense destructive power. Along with Yahaba, she attacks Tanjiro and Tamayo in Asakusa under Muzan's orders. Her attacks include smashing through building walls with her temari, pulverizing Yushiro's head, and blowing back Nezuko's leg when she tries to kick back the temari, showcasing her full strength. However, after Yahaba is defeated, she falls under Tamayo's spell and inadvertently speaks Muzan's name, triggering a curse. A giant hand grows from her mouth, and the remaining cells of Muzan within her body destroy her, reducing her to dust in the morning sunlight. Tanjiro reflects that she was probably just a girl who loved playing with temari balls when she was human. According to the fanbook, the temari were gifts from her father during her human life.
