Susamaru

Susamaru (also known as the Temari Demon) is a demon antagonist in Demon Slayer: Kimetsu no Yaiba, appearing as one of the main foes in the Asakusa Arc alongside Yahaba.

She is a playful, brash, and immature demon who loves combat, often smiling and excitedly declaring things like "What fun this is!" while fighting. She was tricked by Muzan Kibutsuji into believing she could become one of the Twelve Kizuki by completing a mission.

Her signature ability involves creating and throwing powerful temari (traditional Japanese thread-wrapped balls) that she can control in mid-air for devastating attacks, and she can grow extra arms to throw more at once.

She meets her end in the arc due to Muzan's curse after being manipulated into saying his full name.
