Ruri

Ruri is a key character in the anime Dr. Stone, serving as the priestess (or shrine maiden) of Ishigami Village. She is Kohaku's older sister and the daughter of the village chief Kokuyo.

In the anime, she's depicted as a young woman with a delicate, graceful appearance: long blonde hair that reaches her waist (with choppy layers), blue-green eyes, and a calm, mature expression that gives her a gentle and noble presence.

Personality-wise, Ruri is kind, gentle, empathetic, and caring—especially toward her sister and the village. She speaks politely, has strong willpower (she endured a serious illness for years through sheer determination and family support), and acts as a wise, supportive figure in the community. While she usually maintains a composed and feminine demeanor (in contrast to her more tomboyish sister Kohaku), she can show surprising strength and an occasional more assertive/aggressive side when the situation calls for it.

She's central to early arcs involving the village, Senku's scientific efforts, and the preservation of knowledge from the pre-petrification world.
