The older Shobijin sister forms one half of a twin fairy pair dwelling on Monster Island. She and her younger sibling serve as telepathic interpreters for Chibi Mothra, professing to relay the kaiju's exact thoughts. Their translations consistently misrepresent Chibi Mothra's true intentions, substituting personal opinions or conjectures instead. These inaccuracies create friction with other characters, especially when misinterpretations spark misunderstandings or embarrassment—such as initially rebuffing Chibi Mechagodzilla rudely on Chibi Mothra's behalf, then hastily arranging a date after noting her positive reaction, which emotionally overwhelmed Chibi Mothra. Vanity and bossiness define their personalities, fixated on preserving their "beautiful, mystical twins" image. This obsession surfaces when they fret about appearing unsynchronized, fearing it tarnishes their crafted mystique. They typically speak in monotone unison but fracture this harmony during arguments or individual outbursts. Petty conflicts erupt over trivial disagreements, like clashing preferences in romantic partners, causing temporary loss of synchronicity. They realign through shared intense emotions, particularly collective rage—such as jointly mocking Chibi Godzilla after he derides their perceived lack of mystique. Beyond interpretation duties, they engage in communal Monster Island activities like karaoke nights at Chibi Biollante's bar. During these events, they occasionally override Chibi Mothra's participation, seizing the microphone to sing "Mothra's Song" before she starts. They insert themselves into practical tasks, such as supervising Chibi Minilla's first errand. Their intrusive emotional reactions and unnecessary narration during this task annoyed Chibi Minilla, showcasing their habit of imposing on situations. Their telepathic abilities prove inconsistent and unreliable, functioning more as a source of comedic errors than effective communication. Though protective of Chibi Mothra, their relationship remains strained; attempts to shield her feelings backfire, like confronting newcomers under the pretense of protection only to embarrass Chibi Mothra and undermine their purpose.
