Ranka Otenba appears in the anime series. During Episode 17, she is falsely accused of eating a fishman's fish, an act actually committed by Muka Muka. This leads to her receiving comedic spanking as punishment from the fishman. In Episode 36, she reacts with disgust towards the main character Uiba's excessive and inappropriate behavior, joining others in expressing disapproval. A notable trait is her distinctive "Noblewoman's Laugh" (ojou-sama laugh), reflecting an aristocratic or refined mannerism. Information regarding her background story, family origins, or development in additional media like movies, OVAs, or spin-offs is not available.
