Hanazono Shizuma is the secondary protagonist in Strawberry Panic!. She is voiced by Nabatame Hitomi.
Shizuma is seventeen years old. She 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 Rokujo 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 Aoi 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.
Hanazono Shizuma is the current Etoile. She is a highly respected and much beloved person to most of the other students attending the three schools. She looks very mysterious and also seems to have a number of secrets to match this visage. This makes her a difficult person to figure out or to even talk to, for someone just meeting her.
Most of her secrets and personal problems, seem to be related to her prior relationship with Sakuragi Kaori, her now-deceased Etoile partner.
Shizuma is very skilled on the piano and likes to play it constantly. She also played Carmen during the school drama a year before the series and then the prince.
Nagisa was the first to catch Shizuma's attention. She also became the center of envy as well as the attention of the whole student body when Shizuma had greeted her though she was late. At first, Shizuma states that she only wants to play with the girl for a while but it seems to Miyuki that she is slowly falling in love with the transfer student. Also, Nagisa was the only person who had persuaded Shizuma from skipping responsibility and to attend the council's meeting. Miyuki was utterly surprised along with the other council members. As the story progresses, Shizuma was reluctant of her feelings to Nagisa and in the end had made up her mind, that she is in love with her. During the Etoile election, she runs to the venue and makes a sudden entrance by slamming the doors. She walks to the center of the crowd, spreads her arms and shouting her feelings. The whole student body was stunned. Suzumi Tamao secretly smiled and pushed Nagisa to run away with Shizuma and forfeit in the election. Shizuma and Nagisa were running till they reached the woods and laid in the ground.
She has a friendly relationship with Miyuki.
