Orihime was once a member of the legendary idol unit Masquerade and was known as "Hime" (ヒメ lit. Princess). At the peak of Masquerade's popularity, she and her partner, Miya, disbanded with Hime removing her mask, and Miya leaving the stage without doing the same. As of now, Orihime is the current headmistress of Starlight Academy.
Orihime is an adult woman with dark blue eyes and medium-length, curly brown hair. She has a blue color scheme and is depicted in a fashionable suit with a powder blue scarf around her neck.
Orihime is a kind yet stern woman. She sometimes acts as a voice of guidance for the idols of Starlight Academy and rarely loses her cool. She is shown to be rather patient and has a high degree of faith in the idols of Starlight, especially Ichigo and her friends. In the anime, Orihime always keeps track of the activity going with her idols and tends to, as Johnny puts it, "search for excitement". Despite the fact that this claim was proved many times in the series, Orihime never truly denies it.
- She is sometimes called "Gakuen Mother" by Johnny Bepp.
- Orihime is shown to be commonly annoyed by Johnny's various antics at times.
- "Orihime" is another name for the star Vega and the name of the weaving goddess and lover of Hikoboshi (Altair) who is celebrated during Tanabata.
- She is the first known idol to have beauty mark, followed by Sora Kazesawa and Nono Daichi.
- But her beauty mark not always shown in each episode.
- Aikatsu! Photo on Stage!! confirms her as a Sexy type idol.
