真壁 愛洲

The main heroine.
She is a part-time waitress at Ao's favorite cafe-bar.

She is serious and firm.
She has an excellent academic record and is good at housework in general.
She has never experienced love because she is always busy with her studies and part-time jobs. Although she does not usually show it, she has a pure and innocent girlish heart.

Aisu has only ever bought fast fashion lingerie, but when she visits 'LingerieS' to meet Aoi, she becomes interested in high-end lingerie.
