郷愁

An anime-style nostalgic landscape with Serena-san standing still. Serena has long hair, wearing a traditional nun outfit in black with modern elements, including red accents, and a hood over her head. The scene captures a peaceful, natural setting with a gentle river flowing nearby, surrounded by lush greenery, tall trees, and flowers. The sky has a warm, golden hue from the setting sun, casting a soft glow over the entire scenery. Serena stands quietly, taking in the serene and nostalgic atmosphere, drawn in a detailed and colorful anime style, with no buildings in sight.
