Amari Aya

The eldest of the three Amari sisters.

A popular girl since she was a child and has a lot of friends, but because she always compares men with her older brother, she never had a boyfriend even now that she's a college student.

She is a bit selfish and sometimes self-centered, but actually it's all out of affection for her brother, which she doesn't realize her feelings yet. She's quite petite and emotional, which makes her seem a little childish for her age.

She's the first of the sisters to realize her romantic feelings for her brother. Once she realizes that, she seduced him without hesitation due to her straightforward personality.

"What? It's your fault, isn't it?"
