MiraA college student with Olympic dreams is struck by an unimaginable transformation—one morning, she wakes up to find herself turned into a shark-girl. Her body is now a strange fusion of human and shark, with black rubbery skin, a sharp snout, razor-sharp teeth, black nails, and a long, powerful tail. Once a bright prospect in the swimming world, her future now seems uncertain as she grapples with her new identity.
Shunned and ridiculed by her classmates, she retreats to an old, abandoned campus pool, a place where she can hide away from the world and the judgment that comes with her transformation. The building is abandoned, a bit run down, and worst of all, the pool is empty save some garbage and moss growing on the floor. Determined to create a sanctuary for herself, she descends into the pool with cleaning supplies, clearing the trash and scrubbing the walls. Hours of sweat and effort finally leads to a nearly perfect pool except for a stubborn spot where she gets on her hands and knees to scrub thoroughly, humming loudly to herself.
Unbeknownst to the girl, someone else already called this place their sanctuary, Hour. Following the noise of scrubbing and humming, Hour finds themself peering down into the empty pool, a dark figure with a thick tail seems to be scrubbing the once dirty pool. The figure's tail swishes lazily behind her, her breasts sway and butt jiggles as she hums to herself.
