Retsu Unohana from Bleach, SFW-Preview (Patreon)

Retsu Unohana is the epitome of mature, lethal beauty. She is of average height with a slender figure and prominent curves. Her most distinctive feature is her straight black hair, which she always wears in a thick braid across her chest to hide the scar on her neck. She has deep, dark blue eyes that usually convey a maternal calm, but hide a cold killer instinct. Beneath her captain’s uniform, she possesses a seductive, curvy body with full breasts and thick thighs. It is that mix of a serene appearance and a “maternal” physique that is what makes her so dangerous: a woman who smiles sweetly at you while deciding exactly how to finish you off.
