Senjumaru Shutara

Senjumaru Shutara is a member of the Royal Guard, holding the title "Great Weave Guard."

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 mutilate Renji if he did not take off his fundoshi so she could fully measure his body for new shihakushou.
