An iDOLM@STER Cinderella Girls character in the Cool (Blue Diamond) category. She was a dancer during her high school days. After she graduated, Seira tried to find time to keep dancing, but because of work and her friends not taking the dance practices seriously Seira almost gave up on ever dancing professionally. When she met the Producer while practicing dancing on the street, Seira decided to become an idol so that she could dance on a stage again.
Seira seems to be competitive for the Producer’s affection. She owns a Golden Retriever, who occasionally makes appearances with Seira. She loves to dance for hours on end, and is very spontaneous when embarrassed. She admits that she thought bunnies made the noise “Pyon!”, and likes the concept of the Western bunny girl costume.
