Senjumaru Shutara is a member of the Royal Guard, holding the title "Great Weave Guard" (大織守, Ōorigami). She holds the position of Fourth Officer of the Zero Division (零番隊 第四官, Zerobantai Daiyonkai), as well as "Divine General of the North" (北方神将, Hoppō Shinshō). Senjumaru has the appearance of a slender and very youthful woman with fair skin and long, black hair that is adorned at the back by a large golden ornament in the shape of a crescent moon with numerous small lines radiating outwards. Senjumaru wears the standard Shinigami shihakushō beneath a white long-sleeved haori, over which she dons a further white robe fastened at the front near the center of her chest. Her height makes her the shortest among other members of Zero Division, but she wears a pair of extremely thick-soled okobo. She has six long, golden skeletal artificial arms attached to her back that she uses in place of her physical hands. Senjumaru is somewhat playful, providing a fanfare with several musical instruments upon the Royal Guards landing in Soul Society and taunting Mayuri Kurotsuchi. She is also focused on the mission they have been given, seeing it through while other Royal Guard members talk with each other and the Gotei 13. She can be rather forceful as well, to the point of threatening, as she threatened to castrate Renji if he did not take off his fundoshi so she could fully measure his body for a new shihakushō. When referring to herself, Senjumaru uses the archaic pronoun "warawa".
