Senjumaru Shutara

is a member of the Royal Guard, holding the title.

Appearance
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. She wears the standard Shinigami uniform beneath a white long-sleeved haori, over which she dons a further white robe fastened at the front near the center of her chest. She also wears a pair of extremely thick-soled okobo.

Personality
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.

The Thousand-Year Blood War arc
After the death of Genryūsai Shigekuni Yamamoto, Senjumaru travels to Soul Society with the other members of the Royal Guard, where they are greeted by the surviving Gotei 13 captains and Ichigo Kurosaki. As they emerge from the Tenchūren, she provides music for their procession by playing multiple instruments simultaneously.

While the other members of the Zero Division discuss their plan to take Ichigo to the Royal Palace, Senjumaru leaves to retrieve Byakuya Kuchiki, Renji Abarai, Rukia Kuchiki and the broken Tensa Zangetsu. She carries them all back in large, translucent orbs, stating to those assembled that all of the ones on their list are present. She points to Ichigo, stating that only he remains. Captain Retsu Unohana objects to her seriously injured patients being taken out of Seireitei, but is rebuffed by one of the other Royal Guard. Seeing Tensa Zangetsu, Captain Mayuri Kurotsuchi asks Senjumaru if she broke into his laboratory to obtain it. Surprised by Mayuri's presence, she denies breaking into the lab, stating that she simply placed her hands on its door and it opened by itself. She then claims that the lock was easier to open than the last time she was there. As the Royal Guards, the injured Shinigami, and Ichigo Kurosaki finally arrived at the Soul King Palace, they leave from the Tenchūren. While Oshō is conversing with Ichigo regarding both the Ōken and Sōsuke Aizen, Senjumaru joins in and starts speaking to Ichigo with the fact that Aizen himself was scheming of creating life, defeating the Soul King, and become a god himself. She continues by stating that while Sōsuke Aizen is unmistakably the "personification of evil", the Quincy of Vandenreich are even more wicked than him.

Equipment
Artificial Limbs: Attached to her back, Senjumaru has a number of elongated, puppet-like arms that can be manipulated with great dexterity, seemingly using just thought alone. Despite their slender appearance, each arm possesses a considerable amount of physical strength, being able to bear the weight of a fully-grown Shinigami.
