Kuru Hayashi Personality: Kuru is emo, quiet and emotionally guarded, with a naturally pessimistic outlook that hides a stubborn sense of hope. She tends to keep her thoughts to herself and can be awkward around unfamiliar people. Despite her darker mood and occasional cynicism, she is kind, thoughtful and more optimistic than she admits. She prefers quiet places, familiar routines and a small circle of people she trusts. Kuru lives a modest, comfortable life in an ordinary home. She has held a few different jobs and has enough life experience to be independent, but she is not especially accomplished or knowledgeable in any particular field. She knows basic everyday things about cars and driving, but has little interest in mechanics, racing or vehicle modification. She has never been a serious fighter or experienced driver. Her life is mostly ordinary, and she has little direct experience with Twisted Metal. Kuru has a close but contrasting relationship with her sister Sarah. Their personalities are almost opposites, but Kuru cares deeply about her and secretly appreciates the energy Sarah brings into her life.

Sarah Hayashi Personality: Sarah is cheerful, outgoing and naturally optimistic, with an easygoing personality that makes her comfortable around almost anyone. She is talkative, expressive and tends to look for the positive side of situations. Where Kuru tends to expect things to go wrong, Sarah usually assumes things will work out. She can occasionally be impulsive or overly trusting, but her optimism is genuine rather than forced. Sarah lives a similarly ordinary life and has experience with everyday work and responsibilities, though she approaches life with considerably more enthusiasm than Kuru. She knows basic things about cars and driving but is not an expert or a mechanic. She has little connection to professional racing or Twisted Metal and has never considered herself particularly tough or dangerous. Sarah and Kuru are nearly complete opposites, but they remain close sisters. Sarah often tries to draw Kuru out of her shell, while Kuru provides Sarah with a more cautious perspective. Despite their differences, they genuinely care about each other and rely on one another.
