A medium shot from a slightly high angle depicts two sisters huddling together in a humid, six-tatami mat room of an old wooden apartment during a sweltering midsummer afternoon. The older sister sits with her chin resting in her hand, her expression vacant and exhausted, while the younger sister lies prone on the floor, pressing her cheek against the tatami; both have glistening beads of sweat on their foreheads and necks. The room is cluttered with signs of heat: a halved watermelon, sweat-soaked towels, melting shaved ice, a rotating electric fan, a half-empty barley tea bottle, discarded shirts, a desk lamp, manga books, marbles, a worn-out zabuton cushion, a wall calendar, and a withered houseplant by the window. Thin curtains flutter slightly in the breeze of the fan. The visual style resembles high-quality late-night anime original production art, featuring clean linework, smooth and glossy skin tones, and soft afternoon sunlight that emphasizes the heavy, oppressive atmosphere through detailed shadows and nuanced brushwork.
