Yenra Kokoro, Darling in the Franxx Kokoro Tsurumaki - School Uniform Illustration: A young girl with long blonde hair wearing a school uniform consisting of a gray blazer, white shirt, black tie, and plaid skirt. She has her hands raised to her chin, and the background is darkened to focus attention on the subject. The overall impression suggests that this might be an illustration or painting from a manga series, possibly 'Kokoro Tsurumaki' or another similar title.
