Leon's de facto little sister, though they're not actually related by blood. She sees him as her real older brother and takes it upon herself to look after him—mostly because he's basically helpless at everything except research. She's got this infectious cheerful energy and genuinely doesn't scare easily, no matter who or what she's facing. Fans often note that her upbeat personality and willingness to jump into anything is what keeps Leon grounded in day-to-day life.
