While various other characters and narrative text describe Vivian using masculine terms such as otoko ("man"), and otōto ("little brother"),[3][4][5][6] Vivian initially describes the shadow sirens as san shimai "three sisters",[3] and routinely uses the feminine first person pronoun atai. However, in Super Paper Mario, Vivian's Catch Card describes her using the term otoko no ko,[7] a Japanese-language term that can interchangeably refer to a feminine-presenting man or a crossdressing man, rather than "transgender" (which is identical in Japanese to the English-language word) or okama (a term for an otherwise masculine man who dresses as a woman, sometimes used as a slur to refer to trans women, even in family-friendly media at the time). However, Vivian never refers to herself this way.
