robin_\(honkai:_star_rail\), stelle_\(honkai:_star_rail\), two girls standing on stage in a grand opera house in the morning. Robin has long, flowing blue hair with hints of purple and green eyes. She wears a black sleeveless shirt, a white shirt, high-waist black pants, and a black choker. She stands with her arms relaxed at her sides, looking at Stelle with a light smile and closed mouth. Stelle has grey hair styled in two side-up buns with a large black hair bow, and yellow eyes. She wears a pink frilled shirt, a black frilled skirt, black kneehigh socks, and black footwear. She smiles with her mouth open, appearing cheerful. Between them is a large magician's transparent reinforced glass water escape tank, rectangular with a dark metal frame and brass bolts, open top, filled with crystal clear water, showing gentle ripples and tiny bubbles on its surface. The stage is illuminated, creating a dramatic and magical atmosphere, with high detail on textures like glass, metal, water, and fabric, capturing a sense of anticipation and performance.
