Ururu Tsumugiya is an employee of the Urahara Shop.
Ururu is a young-looking girl with a perpetual blush on her cheeks who wears a white t-shirt with the Urahara Shop logo in pink print and a knee-length, pink skirt with white dots. She has round purple eyes and long, black hair with a purple tint. It is parted down the middle, with two strands of her bangs in the middle of her face, opposing each other. The rest of her hair is in pigtails with pink ties. Seventeen months after the defeat of Sōsuke Aizen, Ururu no longer has pigtails with shorter strands between her eyes. She also wears a school uniform and sports a noticeably fainter blush.
Ururu is a very quiet and shy person and is very polite to those around her. When asked to help, she does so happily. When she mistakenly sells poor quality merchandise to a customer, she becomes upset and cries, apologizing for her error. Ururu seems to respond robotically when she is injured or when Hollows appear. Jinta Hanakari also mentions that she reacts to strange spiritual presences, such as those of Arrancar. During such times, Ururu takes on a rather simplistic view of right and wrong.
She considers those that cause harm (relative to her) as enemies, and believes that enemies must be eliminated, though she never attacks Jinta, despite his tendency to pick on her. She and Jinta are seen bickering a lot. Jinta tells her what to do, despite her being three years older, and she usually does it without question. She seems meek and timid, but this is at odds with her great power. Seventeen months after Aizen's defeat, Ururu appears to have emotionally matured, appearing more calm than meek.
Ururu's origins are unknown.
