Ururu is a meek, black-haired girl who mostly does manual labor for the shop, as well as assisting Urahara in training Ichigo. She is Karakura Pink in Don Kanoji's superhero team and uses a multi-barreled cannon as her weapon. She seems to respond robotically when injured or when hollows initially appear. Jinta also mentions that she reacts to strange spiritual presences, such as those of arrancar. During such times, Ururu seems to take 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.

Ururu's meek attitude is somewhat at odds with her fighting ability, which is undefined, but quite high (Urahara vaguely mentions that her fighting ability is at an "anti-shinigami" level). Her leg-strength in particular is far greater than it should be, even when compared to Kon while he's in Ichigo's body. Her combat skills are shown when she gives the arrancar Ilfort Grantz a devastating kick to the head while he is fighting with Renji Abarai, overpowering him to the point that he is forced to release his zanpakutō. In the anime, she also delivers a powerful kick to Sawatari's giant whale doll, Baura.
