BRIGHT：LIGHTS in ナイトプール

sagisawa_fumika, tachibana_arisu, idolmaster_cinderella_girls, two young female idols, Sagisawa Fumika and Tachibana Arisu, are depicted in a night pool scene on a luxurious rooftop swimming pool. Fumika has long, dark blue hair with messy bangs framing her face and long hair strands. She wears a modest, elegant navy blue one-piece swimsuit with subtle ruffles and is submerged in the dark blue water, which glows with neon lights from below. Her skin is wet and glistening with water droplets, and she has a gentle, shy smile on her face. Arisu has long, dark hair tied in twin tails and blue eyes. She wears a cute, light blue and white checked bikini with small ribbons and frills and sits on the poolside with her legs dipped in the water, her expression cool with a slight blush on her cheeks. The water's surface reflects the night city skyline in the background, with palm trees visible. Steam rises from the water, and the overall atmosphere is non-erotic and innocent. The composition is dynamic, shot from a slightly below angle, with sharp focus on their beautiful, detailed eyes, perfect anatomy, and detailed faces. The lighting is cinematic, with underwater lighting and reflections, creating a high-quality, ultra-detailed, and atmospheric image.
