murasaki_shion, masterpiece, ultra detailed, a young girl with long grey hair and yellow eyes, wearing an idol outfit inspired by hololive 1st live, dominated by white with contrasting accents. She has a large bow, a luxurious frilled skirt, a volumized pannier, and mismatched thigh-highs. She is climbing a glowing transparent glass staircase in a concert venue, seen from a low-angle dramatic perspective looking up from beneath the stage. She wears a radiant, full-faced smile, with her hands positioned perfectly. The scene is illuminated by sparkling stage lights, with light effects spreading from her feet and countless penlights waving below. The atmosphere is cinematic and filled with concert energy, focusing on her dynamic expression and the elaborate stage setup.
