In the anime Stella of the Theater: World Dai Star, Dugong is a small otter who resides at the Sirius bathhouse. Serving as a kind of mascot for the theater company, this creature is most often seen swimming and playing in the bathtub, an activity it particularly enjoys. While its daily life is simple and revolves around the bathhouse, Dugong holds a peculiar significance within the world of the story. A notable superstition is attached to the animal, as it is said that any person followed by Dugong is destined to become a Dai Star, the title for a top-tier theatrical performer. This belief elevates Dugong from a mere pet to a living, four-legged omen of success and potential. In its role within the narrative, the otter acts as a lighthearted and charming element, providing moments of calm and cuteness. Its interactions with the cast are generally passive, though it has been known to bite certain characters, an action that can serve as a simple gag or a sign of the animal's unpredictable nature. There is no deeper exploration of its personality, motivations, or any significant character development throughout the series. Its primary function is tied to the superstition of fortune and its presence as a beloved animal companion of the Sirius troupe. Outside of its affinity for the bathhouse and its reputation as a herald of stardom, Dugong does not possess any notable dramatic or supernatural abilities.
