character: ereki_(beatmania), A detailed anime illustration, great quality,best quality, showing a medium shot of a blonde long-haired girl with an ear piercing, wearing a black oversized parka and a white skirt, sitting atop a stone wall in a narrow alleyway under a starry night sky. She is actively playing a black and white electric guitar, her left hand firmly fretting chords on the neck while her right hand strums the strings near the body. Her expression is focused and cool. The stone wall is textured and weathered, and translucent glowing jellyfish float gracefully in the dark blue night air around her. The background features other alley walls and glimpses of the vast, sparkling starry galaxy. Dramatic lighting from an unseen streetlamp casts sharp shadows, with a cool color palette dominated by blues and blacks, accented by the guitar's white and the girl's blonde hair, creating a mysterious and atmospheric urban night scene.
