Shizuma Hanazono is the love interest of Nagisa Aoi from Strawberry Panic! She is voiced by Hitomi Nabatame.
Shizuma has a long silver hair and light green eyes, although there are times that they were either yellow or gold. She has a feminine stature and is tall. She is mostly seen wearing St. Miator uniform and dresses on either casual or formal occasions.
When Shizuma first became Etoile with Kaori, her partner, she's been very cheerful and lively. However, since Kaori's death, she's been locked up in her room always and the cheerful and lively character turned to depressed, almost blank. She was very hard to read and predict which somehow annoys Miyuki. Much of the time, she doesn't enjoy the dull work of the Etoile, so she often finds ways to skip her duties.
She met Nagisa and behavior changed once again, much to the student council's surprise and mostly Miyuki. The lively Shizuma somewhat came back again and her naughty, playful personality.
She also has a kind of playgirl attitude as seen in the series. Once, Nagisa saw Shizuma in the woods with another student whom she was about to kiss but was interrupted and the student had ran away with a flushed face.
