Etoile and the second half of the best pairing in Strawberry Panic. Shizuma & Nagisa is Beauty.
The current Etoile, Shizuma 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 image. This makes her a difficult person to understand or to even talk to for anyone except those closest to her, which is not very many people. Shizuma is often haunted by her previous relationship with Kaori, who died after suffering from a terrible disease.
She is very skilled on the piano and likes to play it constantly. Much of the time, she doesn't enjoy the dull work of the Etoile, so she often finds ways to skip on her duties, much to the annoyance of the other notable people on Astrea Hill. However, Nagisa manages to persuade Shizuma to resume performing her duties, and live up to the expectations of those around her. She is a skilled actress and has participated in Astraea's annual play twice, playing Don Jose in the production of Carmen . She is also noted to excel in French, which is a key part of the storyline because of the tutoring she gives to Nagisa throughout the series.
Shizuma seems to have developed a deep emotional tie with Nagisa. Despite initially seeing Nagisa as just one more pretty girl to get close with, Shizuma eventually comes to see her as different, displaying a very strong possessive streak with regards to Nagisa. Early in the development of her relationship with Nagisa, she is only trying to replace the hole in her heart left by her former Etoile partner and first love, Kaori, who had died the same year they had been elected as the Etoile. Towards the end of the anime, after a series of guilt-ridden conflicts and her own self-discovery, Shizuma realizes she is truly in love with Nagisa.
An extremely emotional character Shizuma suffers from some obvious form of depression, and is not initially aware of the effect he flirtatious manner has on others. She does eventualy develop the ability to find love once again, when her emotional opposite is found in Nagisa. Her and Nagisa are very different to be sure, but they make a great couple and cancel the other persons negative traits out.
