Otohime is a human character in the film Pui Pui Molcar the Movie: MOLMAX. She is the proprietress of Ryugu-jo, a tourist spot in the world of the film, and she is presented as a capable administrator who oversees the attraction. Her title as princess and the name of her establishment echo the Dragon Palace and its princess from the Japanese folktale of Urashima Taro, giving her a storybook quality within the setting.

In the story, Mol City has entered a high-tech era in which drivers are switching to new AI-driven Molcars, and Molcars have begun disappearing. After the Molcar Potato and his friends are saved by a skilled driver who is searching for his missing partner Molcar Dodge, the group sets out to find the missing Molcars. During this journey they visit Ryugu-jo, and Otohime appears there as the person in charge of the location, acting as the host during the travelers' stop at the tourist attraction. Her role in the film is a supporting one: she represents one of the destinations the group encounters during its search, and her competence as an administrator is the notable ability attached to her character.
