Susamaru

Susamaru is a demon girl who appears to be a young child with a bob haircut and an archaic, courtly manner of speaking.

She behaves like a playful, doll-like child, laughing frequently and treating battle as a game, yet she is cruel and revels in destruction and killing.

She habitually refers to herself with the pronoun “I,” though on rare occasions slips into an old-person style of “I” that matches her old-fashioned speech.

She loudly calls herself a member of the Twelve Kizuki, but this is a lie Muzan Kibutsuji fed her, and she bears no rank or number on her eyes.

According to Tamayo, Susamaru is far too weak to be considered on the same level as the true Twelve Kizuki.

By comparison, a genuine Lower Rank such as Rui, the Lower Rank Five, is portrayed as vastly stronger than Susamaru and her partner Yahaba.

Her combat style centers on her blood demon art Temari, where she attacks with powerful balls that can pulverize bodies and buildings.

Although she appears childish and fun-loving, her love of temari play has been twisted into a lethal game as a demon.

Her voice actress in the anime adaptation is Mikako Komatsu.

Under Muzan Kibutsuji’s direct orders, Susamaru teams up with Yahaba to hunt down Tanjiro Kamado in the Asakusa area.

Their mission is to take Tanjiro’s head as a tribute to Muzan, proving their worth and, in Susamaru’s mind, securing her position among the Twelve Kizuki.

Susamaru and Yahaba track Tanjiro to Tamayo’s hidden residence.

They launch a surprise attack, smashing through the building’s walls with temari and attempting to kill Tanjiro, Nezuko Kamado, Tamayo, and Yushiro.

Fighting alongside Yahaba, Susamaru initially overwhelms the group.

Her temari are incredibly fast, and when combined with Yahaba’s ability to alter trajectories, their attacks become almost impossible to predict or block.

Tanjiro eventually defeats Yahaba by adapting his Water Breathing techniques, including a modified Second Form called “Horizontal Water Wheel.”

With Yahaba gone, Susamaru is left without the vector manipulation that had made her attacks so fearsome, though her raw power remains terrifying.

During the continued fight, Susamaru grows more serious and reveals that she can sprout up to six arms.

With these extra limbs, she can wield and hurl multiple temari at once, turning the battlefield into a deadly storm of flying projectiles.

Despite her brutality, Susamaru’s battle retains the atmosphere of a “game” to her.

She laughs in a high, gleeful tone, enjoying the destruction and the challenge of facing demon slayers.

The turning point in the battle comes not through raw power, but through Tamayo’s blood demon art.

Tamayo uses a technique called “Scent of Daylight”, a sort of magical truth serum that weakens mental resistance and lowers brain function.

Under the influence of this art, Tamayo deliberately insults Muzan Kibutsuji, calling him a coward and provoking Susamaru.

Susamaru, fiercely loyal and proud of her master, angrily tries to defend him and falls directly into Tamayo’s trap.

In a rage, Susamaru shouts back that Muzan is not a small-time weakling and declares that he is the strongest, calling him specifically by name as Muzan Kibutsuji.

This act triggers the curse that Muzan places on demons who are forbidden from speaking his name aloud.

As the curse activates, Susamaru becomes tearful and panicked, realizing too late what she has done.

She begs desperately for forgiveness, crying out for Muzan to spare her and apologizing, but the curse is absolute.

Grotesque giant hands erupt from her mouth and stomach—manifestations of Muzan’s power—and crush her body from the inside out.

Her entire form is pulverized like minced meat, an extremely gruesome and painful end, showing Muzan’s ruthlessness even toward his loyal underlings.

Even as she is being destroyed, Susamaru’s instinctive attachment to her temari remains.

Her scattered remains continue to reach for her ball, and Tanjiro gently places her original temari next to what is left of her body.

In her final moment, Susamaru tries to speak as if she were an innocent child again.

Her fading voice murmurs something like “Let’s play…” as she vanishes in the morning sunlight, hin
