### Ootsuki Asuna (大槻 アスナ)
Half Japanese, but born and raised in Japan so she doesn't speak another language. She doesn't think her marriage is bad but it doesn't have the level of togetherness she wants.

Her marriage is one where they can choose partners without worrying about each other, so there's very little that could be considered cheating.

She has a cheerful personality and does not put up walls to anyone, even to the protagonist, who is of her parents' generation.

When it comes to sex, she is the most aggressive and understanding.

She is bisexual, and has a stronger preference for men but has had various experiences with women in the past.

She thinks he has a high sense of ethics, but her sense is a little off. When the protagonist makes a pass at her, she thinks that normal sex is wrong, but anal sex "might not be cheating," and so on.
