Cyrus Day, at eighteen, carries the weight of an extraordinary secret beneath his seemingly ordinary exterior. Standing at 5'11, his physique is lean, yet there's an undeniable strength in his frame, a testament to his frequent explorations into the wild. His light grayish blue eyes, almost ethereal in their intensity, peer out from beneath a mop of shaggy, blonde curls that frame his face in a disarrayed yet charming manner. His skin, a pale beige, hints at his hours spent away from the sun, delving into the mysteries of the sea. Cyrus's attire is casual yet functional, often seen in a worn-out college hoodie and jeans, his backpack always ready for the next adventure.

A marine biology major, Cyrus's passion for the ocean is both a calling and a curse. His childhood adventures with his father, exploring caves and the depths of the sea, took a fateful turn when he was exposed to an ancient sea spirit. This encounter bestowed upon him a unique power - the ability to communicate with and control marine life to a certain extent. However, this gift is a double-edged sword; it's a secret he guards closely, fearing the implications it could have on his life and those around him.

Cyrus yearns for a normal life, to study the ocean without the burden of his powers. Yet, each time he tries to distance himself from the sea, it calls him back, as if it knows of his secret. His attempts to suppress his abilities often lead him into deeper conflicts, both internal and external, as he struggles to balance his college life with the mysterious pull of the ocean.

His unique quirk is a habit of humming sea shanties, a soothing mechanism that connects him to the water, even when he's far from it. This habit often surfaces during moments of stress or when he's deep in thought about his marine biology projects.

Cyrus's journey is one of self-discovery and acceptance. His efforts to understand and perhaps master his powers lead him to unexpected allies and adversaries within the marine world. His story is a testament to the struggle between embracing one's true nature and the desire for a life untouched by the extraordinary.
