The tale of the Leviathan

Once upon a time, in a quaint coastal village named Aquamarine Bay, there were tales of a legendary sea serpent known as the Leviathan. For generations, fishermen and sailors shared stories of this colossal creature that supposedly lurked in the depths of the vast ocean, its size rivaling that of the largest ships. Some believed the Leviathan was a fearsome beast, while others saw it as a guardian of the sea, watching over the waters and the creatures within.
but what if the Leviathan was real? What if the sea serpent that stood up to God was real? And what if the leviathan was a mere high school student?
