Susamaru

Susamaru (朱す紗さ丸まる Susamaru?), also known as the Temari Demon (手て毬まり鬼おに Temari Oni?), was one of the two primary antagonists in the Asakusa Arc of Demon Slayer: Kimetsu no Yaiba, along with Yahaba. She was a demon who was tricked into believing she was a member of the Twelve Kizuki.

Susamaru was a pale-skinned woman with bright yellow eyes, cat-like slits, and white horizontal slats. She had black hair, transitioning to an orange-colored at the tips, styled with short, spiky bangs at the front. Susamaru wore a pair of long silver earrings and an orange kimono that matched her hair. She had a black haori on top, but took them both off when she entered her battle, revealing a small black sarashi that covers her chest and upper abdomen. Although she normally had an average build, when fighting seriously, her body became noticeably more muscular, in addition to growing two new pairs of arms from her torso and waist.

Susamaru was shown to be rather playful, yet very brash and quite immature while almost always smiling and always enjoys and accepts 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. She was fanatically loyal to Muzan Kibutsuji and battled to the best of her abilities in the hopes of killing Tanjiro Kamado and taking Tamayo hostage for her master. When the latter had denounced Muzan as a manipulative coward, she defended his honour and denied her statements vehemently.

Susamaru was a young girl who enjoyed playing with temaris before she was transformed into a demon. At some point, she encountered Muzan Kibutsuji and was convinced by him that she, along with Yahaba, was a member of the Twelve Kizuki, a group of the most powerful demons in history that serve under him. She became intensely loyal towards Muzan and was incredibly proud of her "position" as a Twelve Kizuki.

Outraged by the appearance of a Demon Slayer wearing hanafuda-like earrings in Asakusa, Muzan summoned Susamaru and Yahaba and ordered them to hunt him down. The two walked the streets of the busy city searching for a trail to their next target. Yahaba used his Blood Demon Art to track the footsteps of a Demon Slayer carrying a large box. Susamaru walked alongside him, bouncing her temari as she follows along. Yahaba soon found that the Demon Slayer was accompanied by others. Excited to slaughter them all, Susamaru asked how they should go about destroying them. Yahaba replied that, they must execute them vindictively for Muzan, much to Susamaru's liking. She followed her partner to an invisible house hidden behind a fake wall, and used her temaris to destroy the seal hiding the building. Having tracked down their enemy, Susamaru agrees with Yahaba that they must kill them all brutally. Using Yahaba's arrows to guide her handballs, Susamaru tears apart the house. After making a large enough opening to see inside the house, Susamaru notices the Demon Slayer with hanafuda-like earrings, Tanjiro Kamado, inside. Yahaba scolds Susamaru for her immature approach and for splattering dust on his kimono. Susamaru ignores him and continues having fun, replying only that Yahaba needs to relax and let loose on the enemy. Yahaba falls back and uses his arrows to guide Susamaru's temari to Yushiro's head, instantly decapitating him. Susamaru tells Tanjiro that it's time for him to die and throws a temari straight towards him. He counters by stabbing the ball at an angle, impressing Susamaru. Yushiro's head regenerates and he curses the Temari Demon for ruining his peace with Tamayo. Susamaru claims he's babbling and removes her kimono to grow four more arms. She tells them all that they are about to be killed by one of the Twelve Kizuki, asking them if it made them feel special. The Temari Demon prepares six temaris and asks her opponents to keep playing until they die. She tears up the house and injures both Yushiro and Nezuko. The former gives Tanjiro a way to see Yahaba's arrows through one of his talismans, enabling him to effectively counter Susamaru's temari. As Susamaru battles Tanjiro, she tells him that she's going to bring her master Tanjiro's head for sure. Meanwhile, Nezuko attacks Yahaba and dispells his arrows.

Susamaru was a fairly powerful demon, as she was able to hold her own against Tanjiro Kamado and pressure him in battle. Even when Nezuko strengthened herself in order to match Susamaru's power, Tamayo noted that in a drawn-out battle, the Temari Demon would eventually prevail.

Flesh Manipulation: Like all demons, Susamaru possessed the ability to control and alter her flesh to a certain extent. She can use this ability to grow 4 more arms, allowing her to conjure more handballs and increase her offensive output.

Regeneration: Susamaru, like all demons, possessed powerful regenerative abilities, as shown when Tanjiro had sliced off all her arms and she was able to heal just moments later.

Enhanced Strength: As a demon, Susamaru had tremendous physical strength, as she was able to throw her temaris with enough force to smash through walls and decapitate Yushiro. She was also able to kick her handball strong enough to sever Nezuko's leg.

Unlimited Stamina & Endurance: As a demon, Susamaru had infinite stamina and endurance, she was able to endlessly throw her temari handballs without getting tired. She also had all 6 of her arms sliced off by Tanjiro yet still smiled gleefully showing no signs of agony.

Hiasobi Temari (火ひ遊あそび手て毬まり Hiasobi Temari?): Susamaru's Blood Demon Art allows her to conjure temari handballs at will. These handballs are extremely durable, being able to withstand being thrown and kicked at high speeds and destroy any objects they come in contact with. They can, however, be penetrated by a sharp object such as a Nichirin Sword. Susamaru uses her temaris in conjunction with Yahaba's Koketsu Arrows to increase their lethality and effectiveness.
