Shima Katase (片瀬 志麻 Katase Shima?) (or 'Shipon (しーぽん) as she is dubbed by Arisa), is the heroine of the story. She joins the Stellvia foundation's space program so that she could "see the stars while looking forward, rather than having to look up".
In the beginning, she fluctuates between complete confidence in her abilities and believing she couldn't do anything. The series depicts her as extremely diligent, although she is also a natural genius.
As the series progresses, she learns to understand her mistakes and not think that she has to be perfect or else fail. For instance, after a rocky start to her training, during which she was dead last in her class at piloting, she takes the advice of Kouta Otoyama and realizes she was trying to keep track of far too much information on her ship displays. Her piloting improves dramatically as a result. However, she still will lose her confidence often. Once she is like that she will get into a deep depression like a little kid thinking that it is because she does not have talent.
She is called Shipon because the first time she piloted one of the Biancas she flew around like a ping-pong ball.
During the genesis mission she was piloting Halcyon (also called Lucyon by Arisa and Rinna). Some irregularities were interrupting the Infinity, so Halcyon released its barrier and absorbed the irregularities. She almost died at that risk. It is shown that she loves Kouta very much by almost sacrificing her life by saving him from the irregularities.She also participated in the school games.
She and Kouta develop a romantic relationship (they share their first kiss on episode 12). She likes Kouta very much but somehow gets irritated when he can't understand her.
Powers and AbilitiesEdit
Actually, Shima has a rare talent. Shima is offered to be the 5th member of the Big 4, after passing the test. Despite her early setbacks as a pilot, her programming abilities are top notch from the very start, and she eventually combines the two in order to become even more formidable in the cockpit.
