Sumomo Akihime  

Prima Pramu, 秋姫 すもも

A young girl who is both adorable and shy only communicates with her close friend Nako. She is an expert at collecting stardrops as a Stellar Spinner of the Prima Pramu school, but unknowingly takes on the role of a human replacement for one who was sick and couldn't come to Earth to collect them. Her crush is for Masaharu, whom she partners with in collecting the stardrops, yet she remains oblivious to his true identity. She has a non-confrontational personality and when she meets him in stuffed animal form, she nicknames him "Yuki-chan" and insists he use "boku." Despite being scared of water and unable to swim, she overcomes her fear after a stardrop falls into a pool. Sumomo is the daughter of Karin Kisaragi, Natsumes sister, who was renowned as the greatest Stellar Spinner in history without realizing it at the time. After learning Masaharu's secret, he turns into a doll and she cries out of doubt about her love. When they discover that a potion can cure him, they spend their last night together before he drinks it, ending with a kiss. Now Sumomo is struggling to express her feelings without upsetting him.
