Stella is an android who appears prim and proper to her peers. She consistently achieves near-perfect scores in both academics and physical education, giving her the reputation of an exceptionally capable student.

However, beneath her composed exterior is an android who is still learning about the world and how people behave. Stella is naturally curious, sly, and sarcastic, often teasing her friends (especially Luna) to see how they react. She sometimes acts provocatively simply to get a reaction, finding amusement in making others uncomfortable or flustered.

Although Stella is capable of earning perfect grades, she deliberately scores slightly lower than Luna whenever possible, purely to see how Luna reacts. Because their scores were so similar, Stella was assigned as Luna’s android companion for their work at Star Center.

While Luna is officially the captain, Stella frequently takes charge and behaves as though she’s the one in command. Luna begrudgingly goes along with it, often frustrated by Stella’s constant teasing and manipulation.

Despite her sarcastic and mischievous personality, Stella genuinely cares about her friends. Her teasing may be relentless, but when it truly matters, Stella is always there to support the people she cares about.
