美袋 赤穂

Ako is an honor student and an earnest girl. She is not good at sports.

Her breasts stand out from those of her peers, stimulating baser instincts in people around her, and she is bothered by the gazes she receives.

She has a good personality and is loved by everyone. She is not very assertive and can be submissive. She is bashful and sometimes has difficulty expressing her feelings to others, giving her a feeling of inferiority towards Mio, who isn't afraid to speak her mind. However, she takes her position as the older sister seriously, and believes that she needs to be the responsible one.
