Moa is a main character in Show By Rock!! Short!! and a member of the band Plasmagica, serving as its drummer and vocalist. She is an alien from outer space who originally came to Earth with the purpose of investigation, though she keeps this fact somewhat unclear. Her drums are called Super Cosmo. She tends to end her sentences with the phrase Pyuru. She is energetic, bubbly, and excitable, often speaking without thinking and getting into trouble with her bandmates as a result. Despite her alien origin, she holds a part-time job at a bedding store, which sometimes causes her to miss band practice. Moa is naturally curious and enjoys sightseeing in MidiCity under the pretense of her planetary investigation. She compiles reports using a star-shaped CPU and frequently includes a great deal of personal opinion in them. Her music sense is described as cosmic and exceptionally strong among the band members. Moa is friendly and kind-hearted, straightforward in expressing whether she really likes or dislikes something. She is the tallest member of Plasmagica and has long pink curly hair, blue eyes, and animal ears. Her role in the story is as a core member of the band, contributing her energetic drumming and vocals to their performances. She maintains close relationships with her fellow band members, especially Cyan, Retoree, and Chuchu, and her lively personality often drives the group's interactions and comedic situations. Within the series, Moa shows little overt development in terms of backstory but remains a consistently cheerful and enthusiastic presence whose love for music and exploration defines her character. Her notable abilities include her skilled drumming, her alien senses that inform her reports, and her ability to bring high energy to Plasmagica's sound.
