Manami has black hair, styled into twin braids that reach just below her shoulder and brown eyes (lavender in the anime). She wears glasses and has a more petite frame than most of the girls in Class 3-E.
Seven years after graduating Class 3-E, her hair is styled into a single braid, which rested over her left shoulder, instead of her usual twin braids.
Okuda is a shy and rather introverted girl. She has poor language skills and is straightforward because of it. Despite her introversion, she's a sweet and determined girl who hopes to be useful to the class.
