character: takasaki_yu, A medium shot from a dynamic side angle featuring Takasaki Yu riding a sleek, modern jet ski across a sparkling turquoise ocean. Takasaki Yu, a girl with medium-length green gradient hair tied in twintails and bright green eyes, wears Sakimiya Iruka's signature red bikini, which features white accents and bare shoulders. She is gripping the jet ski's handlebars firmly with both hands, leaning slightly forward with a joyful, exhilarated expression and a wide smile as she cuts through the water. The jet ski creates a large, white foaming wake of splashing water and crystalline droplets that spray into the air around her. In the background, a clear summer sky with fluffy white cumulus clouds meets a distant, shimmering horizon. The lighting is bright and sunny, creating high-contrast highlights on the water's surface and a vibrant, energetic summer atmosphere with a vivid color palette of red, turquoise, and deep blue.
