Midori Aikawa trains as a maiko apprentice at a Kyoto geisha house alongside peers Mai Ichinose and Riko Kikuzuki. She possesses black hair and distinctive purple eyes. Her life is profoundly shaped by prosopagnosia, a neurological condition that prevents facial recognition or memory. This forces her to navigate daily interactions and relationships using alternative cues like voices, gait, clothing, and hairstyles. Despite the resulting barriers in her highly social profession—which fuel underlying anxiety about her future—Midori maintains a cheerful, determined exterior, actively developing compensatory strategies while masking her struggles.

Her situation shifts upon meeting Akihito Taira, who faces a complementary challenge: an inability to remember names. They forge a partnership, meticulously memorizing each other’s non-facial identifiers such as voice and mannerisms. This mutual support fosters personal growth and emotional resilience, enabling Midori to confront her fears more openly.

Dedicated to mastering traditional arts like dance and song, Midori’s commitment faces a test when an upcoming festival restricts their geisha house to only two performing apprentices. This limitation strains her bonds with Mai and Riko, transforming their camaraderie into rivalry as each competes for the coveted roles. The emotional distance forces Midori to weigh personal ambition against preserving their friendship, challenging her core values.

Midori’s journey centers on reconciling her condition with her aspirations. Initially concealing her difficulties to blend in, her relationship with Akihito and the pressures of the festival conflict gradually compel her toward vulnerability. This serves as a catalyst for self-reflection on trust and sacrifice. While specific outcomes remain undefined, her path illustrates a progression from isolation toward interdependence, highlighting adaptability in overcoming both neurological barriers and complex interpersonal challenges.
