A medium shot from a side angle depicts a female version of Rengoku as a mermaid, swimming gracefully through a vibrant underwater realm. She has a voluptuous figure and fair, porcelain skin, with a slender face featuring sharp yet gentle features and fox-like makeup around her eyes. Her very long, flowing hair drifts in the current, adorned with numerous lush peony flowers. She possesses a magnificent fish tail with scales and fins that mimic the vivid, flaming red of royal poinciana flowers. Both her body and her tail are intricately decorated with elegant peony blossoms. She is surrounded by various crabs and fish that swim alongside her. The scene is filled with shimmering light filtering through the water, creating a dreamy, high-quality anime illustration with a rich, saturated color palette and a serene, ethereal atmosphere.
