Although she used to be
unable to join long lessons due
to her frail body,
she's overcome her challenge with growth
and is now a standout Stage Girl.
She can be considered
to have a lot of common sense
compared to the other quirky girls of Siegfeld,
and often appears wise because of that.
Her older sister Fumi transferred schools
without telling her why,
and Shiori feels somewhat
reserved about having been left behind.
