Otomune Kozue, with long purple hair, is laughing while splashing water. Hinoshita Kaho, featuring orange hair tied in low twintails, is cheerfully reaching for a colorful beach ball. Uehara Ayumu, with pink hair tied in a ponytail, is smiling brightly while floating in the water. Takasaki Yu, with her characteristic green-gradient hair, is actively batting the beach ball toward the others with her hands. All four girls are wearing cute, colorful swimsuits. The setting is a luxurious night pool with glowing turquoise water, illuminated by submerged lights and surrounding city lights reflecting on the surface.
