Initially born into a lower class, Rukia retains her modesty, even as an adopted member of the nobility. She is graceful and 'clean', yet chooses to talk to ordinary people. However, her cool and lone demeanor often forces her to hide her personal troubles, even from her friends. According to Ukitake, Rukia never opens up her heart, and has difficulty making friends. Rukia is clueless about the ways of the modern Human World. She is very good at acting, having acted her way through a number of tough situations, such as getting out of trouble with school teachers and convincing the Kurosaki family to let her stay at their house. Rukia always has trouble finding clothes that fit her, especially when inhabiting a Gigai in the Human World, leading to her stealing clothes from Ichigo's sister, Yuzu. She likes to climb to high places. Rukia likes everything rabbit-themed, and becomes quite sensitive when someone insults her obsession with them. People often have difficulty understanding her drawings, which are typically rabbit-like, and doesn't like it when people complain about their quality. Rukia's favorite foods are cucumber, eggs, and rice dumplings.
