Hey, Sword Sister

The waters around the Land of Wano were being disturbed by the presence of a jade-colored equine with a horn, running across the sea around the several islands on its bare legs. The speed at which it moved and its consistent pace and movement allowed it to do so, with the side-effect of leaving behind waves of varying sizes, and degrees of danger to surrounding ships and harbors unfortunate enough to be near the one-horned horse.

And yet, more interestingly, was the woman riding on the back of the fanged steed, clutching onto its silver mane, her head lowered to the level of her steed, unfazed by the wind pressure.

From the islands, it looked like a single drill-like stream of water rushing across the sea. Until it crashed into a nearby harbor, bringing about a large wave of waters reaching into the nearest buildings, drenching the surrounding in water.

The woman, clad in an ornate red and blue attire and with distinct silver hair, got down from the horse, petting it "Alright, Jin. Stay put until I come back." She instructed her steed, Jin.

In response, Jin stepped away, each step it took leaving a dent in the ground, either from its weight or strength, going near the waters to lean its head down and drink from the sea directly.
