character: otomune_kozue, character: hinoshita_kaho, character: uehara_ayumu, character: takasaki_yu, A medium shot from a slightly high angle depicts four girls diving deep into a crystalline turquoise ocean, their bodies suspended in the buoyant water. Otomune Kozue, with long purple hair floating weightlessly, wears a cute frilly swimsuit and reaches out with her hand toward a school of fish. Hinoshita Kaho, her orange hair tied in low twintails, swims alongside with a joyful expression, her hands paddling through the water. Uehara Ayumu, featuring pinkish-orange hair in a high ponytail, drifts with a serene smile, her arms gently curving by her sides. Takasaki Yu, with her characteristic two-tone green and black hair, swims in the center, glancing back at her friends with a bright, excited look, her hands gesturing towards the deep blue abyss. The environment is a deep underwater scene with shimmering caustic light patterns dancing on their skin and the sandy seabed below. Tiny oxygen bubbles rise around them, and the lighting is a gradient of bright teal to deep navy, creating a refreshing, ethereal, and serene atmosphere.
