A post-apocalyptic world with a quiet, sunken atmosphere. The scene is a flooded classroom of a ruined Japanese high school. The interior is filled with shallow, clear water through which the wooden floorboards are visible. Several desks and chairs, reduced in number, remain irregularly scattered, some half-submerged. Wet papers and notes are scattered on the floor. One wall of the classroom has partially collapsed, revealing a view of a vast, serene ocean beyond. The sea is calm, wave-less, with a mirror-like surface. The sky is a pale, bright hue, with soft, natural light streaming into the room. A white curtain by the window sways slightly. The overall mood is one of silence and desolation. A young girl is seated on one of the desks. She has pure white, waist-length long hair with straight-cut bangs, translucent white skin, soft E-cup breasts, and gentle, calm silver eyes. She is dressed in a school uniform: a fitted white shirt, a gray pleated miniskirt, and a brown diamond-patterned wool cardigan worn open. A bright red, thin ribbon is tied at her collar. She sits quietly, one leg hanging down, the other slightly bent, her body turned towards the window as she gazes out at the sea, her expression thoughtful and melancholic. The composition is wide, prioritizing the environment over the character; she is placed as part of the scene, not overwhelming it. The style is cinematic, with a focus on the decaying, water-logged environment, creating a profound sense of stillness and abandonment.
