Yū Orie is a high school English teacher who abandoned aspirations for a music career yet performs original songs as a street musician. She is notably seen singing and playing guitar in the rain one evening. Her appearance reflects weariness, with visible exhaustion and a perpetually haunted, resigned demeanor.

She resolves to quit music permanently, planning a final performance while attempting to sell her cherished guitar online. This decision stems from prolonged disappointment and a lack of external validation, cementing her defeat regarding her musical identity. Her songs convey personal turmoil and unfulfilled dreams, with lyrics mirroring her emotional state.

Her musical past resurfaces when student Kanata Asaya recognizes her after a street performance. He persistently requests to create a music video for her song, which she permits. His interpretation clashes with her artistic intent and emotional experience, emphasizing a perspective she does not share. This disconnect arises from their differing creative stages—her resignation at an endpoint contrasts his idealism at a beginning.

Her musical style is characterized as emotionally authentic edgy rock. Visually, she has gray eyes and gray neck-length hair, typically wearing a dress shirt, watch, and ring.

The resolution involves collaborative adjustments to the music video, incorporating others' input to better align with her perspective. This process underscores themes of artistic compromise and mutual understanding, though her ongoing development remains undefined.
