character: fujimaru_ritsuka_(female), character: mash_kyrielight, A medium shot from a side angle depicts fujimaru_ritsuka_(female) and mash_kyrielight underwater, swimming beside a vibrant coral reef. Fujimaru Ritsuka, a girl with short orange hair and an ahoge, and Mash Kyrielight, with short pinkish-purple hair, are both dressed in sleek, form-fitting black neoprene wetsuits. They are equipped with full scuba gear, including diving masks covering their eyes and regulators firmly gripped in their mouths. Fujimaru is positioned slightly ahead, her hand gesturing toward a school of colorful tropical fish, while Mash swims closely beside her, both looking at the marine life with curious, wide-eyed expressions. The background is a lush underwater paradise filled with intricate coral formations in shades of neon pink and orange, with small fish darting through the clear turquoise water. Soft, dappled sunlight filters down from the ocean surface, creating shimmering caustic patterns on their suits and the seabed, evoking a serene and adventurous atmosphere.
