Numa no Himemiko

Numa no Himemiko is a catfish who became a swamp deity and lives in a palace beneath her swamp with numerous fish attendants. Ten years after falling in love with a boy, she asks Nanami to help her meet him again. Quiet but perceptive, Himemiko also seems to notice Nanami's feelings for Tomoe. A makeover from Nanami gives her a more human-looking appearance for the reunion.
