Senjumaru Shutara

Zero Squad Fourth Officer, Senjumaru Shutara, the Northern War God.

Characterized by a large hair ornament and six prosthetic arms on the back, gender is ambiguous (referred to as female by Gerard confronted). Uses the first-person pronoun "warawa" and has a forceful and haughty personality. Known as "The Great Weave Protector."

Seems to be acquainted with Mayuri, often exchanging sarcastic remarks. Refers to Mayuri's lab as "when I was there," suggesting a past in Squad 12 or the Research and Development Institute, though details remain unclear until the end. The term "Shutara Scale" is used within the Research and Development Institute.

The interior of her palace is vividly decorated with various fabrics. She does not hesitate to threaten others to strip naked for measurements.

By covering with a curtain that blends into the scenery, she can hide people behind it and create spaces that mimic reality, projecting false images of herself or buildings. Known for tailoring "Shihakusho" for characters like Renji, she is believed to have introduced "Shihakusho" to the Soul Society.

Initially appears descending to the Seireitei with other members of the Zero Squad to greet Ichigo and others. During a moment of conversation between the Gotei 13 and the Zero Squad, she collects Byakuya, Renji, Rukia, and Tensa Zangetsu. She tailors the highest quality Shihakusho, embedded with the "King's Key," for Ichigo and others upon their arrival at the Royal Palace. However, this inadvertently causes a breach in the barrier protecting the Royal Palace.

Confronts Yhwach and his forces in the Royal Palace, defeats Nianzol but is then shot by Lille's sniper attack. Reveals that the battle was taking place in a fake Royal Palace and the real Senjumaru appears, continuing the fight. No further depiction is provided, but she is defeated by the revived Schutzstaffel.

In the anime, she dominates Uryuu in a fight but underestimates the strength of Gerard's heart after the revival of the Schutzstaffel, leading to her disadvantage. Later, as the most suitable for fighting the Schutzstaffel, she releases her Bankai and annihilates them.

Zanpakuto: "Shigaraki"

A small knife-shaped Zanpakuto resembling a sewing needle. Senjumaru's skill allows her to swiftly tailor or modify enemy clothing into makeshift armor. In the anime, she crafts an umbrella that deflects attacks and stuffs cotton into wounds for rapid healing.

Bankai: "Shatatsukaragara Shigaraki no Tsuji"

Summons a large loom, sealing opponents into fabric. Activated by sacrificing the lives of three members of the Zero Squad, its effects extend to the living world.
