Overview
Rustic girl, or "jimiko" (地味子), is a Japanese term used to describe a type of woman who is perceived as plain, modest, or unassuming in appearance and demeanor. A jimiko woman may dress conservatively, avoid drawing attention to herself, and generally prefer a low-key lifestyle and personality.
The term can convey the nuance of someone who is reserved, introverted, or not particularly attention-seeking. It's often contrasted with individuals who are more outgoing, attention-seeking, and fashionable. While "jimiko" can be used in a neutral or descriptive sense, it may also carry connotations of being overlooked or underestimated due to its understated presence.
They're often characterized by their glasses and their voluptuous body in order to created a sense of gap moe that came from the contrast between their plain personality/appearance and their sexual appeal.
