岡本 ののか

The Maid.A third-year student at Kotogaoka Academy.

She is a clumsy, fumbling girl who often makes mistakes but puts her whole heart into her maid duties.
She gives off a sense of warmth and reliability—the kind of person who is always there whenever you turn around.

She has been working as a live-in maid at the protagonist's family home for a little over a year.
In truth, she has lost her memory, and it is due to these circumstances that she began working as a maid.

Although Koichi is supposed to be meeting Nonoka for the first time, he somehow feels a sense of nostalgia around her.

Commonly called Nono.
