"Sweet one second, sour the next."

Sour Sweet, a high schooler at Crystal Prep Academy, embodies her name with a bipolar personality disorder that swings between obnoxiously nice and sharply sarcastic. Highly competitive and confident in her athletic abilities, she thrives on peer pressure to assert her dominance. One moment, she’s sweetly charming; the next, she’s cutting with her words. Sour Sweet is a fierce competitor who always aims to win, no matter the cost.
