See post #1760084 for base form.
She is portrayed with long grey hair tied into a long braid, brown eyes, and large breasts. Despite her design being based off Hiryuu, she has a starkly different guise because she spent her final sortie in Chinese waters.
Her default base outfit consists of a blue and white vest with green trim, white miniskirt and green thighhighs along with greaves and platform rudder shoes. Most parts of her clothes have cloud-like patterning as a reference to her name (Cloud Dragon). Her rigging is based off her real-life bridge and platforms with several anti-aircraft guns, which can be operated with a built-in trigger, while she uses a staff for her shikigami aircraft with her real-life flight deck used as a banner.
For her kai form, see the corresponding page.
Unryuu is depicted as a highly calm individual, with degrees of her "coolness" varying in several fan works. Some depict her as stoic and somewhat air-headed, others as very ladylike and quiet, or even almost expressionless in some cases. Though many of them usually depicted her as being serious when it comes to her tasks she was assigned to do.
