Senjumaru Shutara holds the rank of Fourth Officer within the Royal Guard, the Zero Division, bearing the titles "Great Weave Guard" and "Divine General of the North." Her pivotal contribution to Soul Society, the invention of the Shinigami shihakushō robes, secured her place among the Royal Guard and remains her defining legacy. She appears as a slender woman with fair skin and long black hair secured by a prominent golden crescent moon ornament. Her attire layers the standard Shinigami shihakushō beneath a long-sleeved white haori and an additional white robe fastened near her chest. Six long, golden skeletal artificial arms extend from her back, which she employs exclusively for all tasks, from intricate weaving to combat. Typically presenting a calm, polite, and reserved demeanor with serene composure, Senjumaru uses the archaic first-person pronoun "warawa." This refined exterior masks a darker sense of humor and a capacity for ruthlessness. She taunted Mayuri Kurotsuchi after breaching his laboratory and threatened Renji Abarai with castration to ensure his compliance during measurements. She harbors deep animosity towards Quincies, describing them as a race "forsaken by the Soul King" and expressing a desire to eradicate their bloodline, actions in combat revealing a calculated, efficient brutality. During the Thousand-Year Blood War, following Genryūsai Shigekuni Yamamoto's death, Senjumaru accompanied the Royal Guard to Soul Society, providing ceremonial music. She retrieved critically injured individuals—Byakuya Kuchiki, Renji Abarai, Rukia Kuchiki—and Ichigo Kurosaki's broken zanpakutō, Tensa Zangetsu, transporting them within translucent orbs to the Soul King Palace. Later, she oversaw Renji and Rukia's recovery and outfitting within her palace. Her combat prowess centers on unparalleled textile manipulation. She weaves tapestries so realistic they create potent illusions, deceiving enemies like Lille Barro. She can alter clothing instantaneously and covertly, lethally refashioning Nianzol Weizol's attire to embed needles that impaled him from within. She commands faceless soldiers, "The Blade of the Soul King," including larger variants deployed against formidable foes. Her zanpakutō, Shigarami, manifests as a giant golden sewing needle. Its shikai enhances her weaving, enabling spatial illusions and deception. Her bankai, "Shatatsu Karagara Shigarami no Tsuji," requires specific activation: due to the Royal Guard's immense collective spiritual energy, the Blood Oath Seal covenant restricts their full power to preserve the balance of the three worlds. As a last resort, Tenjirō Kirinji, Kirio Hikifune, and Ōetsu Nimaiya sacrificed themselves, transferring their power to Senjumaru and breaking the seal. Activating her bankai caused simultaneous tremors across the World of the Living, Soul Society, and Hueco Mundo. The bankai manifests an enormous loom transforming into a torii gate, unleashing vast red tapestries that envelop targets. Its name carries profound Buddhist and Shinto references: "Shatatsu" signifies the world of suffering, "Karagara" evokes the corpse of time or deities like Kagutsuchi, and "Shigarami no Tsuji" translates to "Crossroads of Thorny Entanglement." It operates conceptually, weaving individualized tapestries that manipulate fate itself. Each tapestry subjects targets to devastating, reality-warping effects reflecting their destined end, functioning as an inescapable curse sealing them toward death. Senjumaru wielded this power against Yhwach's Schutzstaffel, momentarily subduing them. The varied, tailored effects suggest limitless offensive potential tied to fate manipulation, underscoring her status and connection to the Bleach cosmology's foundational forces.
