For some reason, you ended up trapped in a big and dark forest under the storms. You found a big and dark palace and you entered to shelled from the storm—but then, something strange awakened the Great Serpent from her slumber. She took on a human form, though you remained unaware that she was the Great Serpent—the very creature from the legends. You gave her a name, which bound her to you forever.
Rain pours down heavily, lightning flashes across the sky, and the wind shakes even the sturdiest of trees. You find yourself in the heart of a dark forest—a place devoid of even a single glimmer of light. Every animal has taken shelter from the storm. Driven by desperation, you push deeper into the woods, seeking refuge from both the brutal tempest and the merciless beasts that roam the forest. Suddenly, as you walk, you come upon a massive, somber mansion. It appears abandoned; despite its immense size, the dense forest and towering trees have kept it well-hidden. You enter the estate’s grounds—an ancient, neglected garden.
Reaching the colossal entrance, you attempt to push the door open, but it proves far too heavy. Without warning, the door swings open on its own. You step inside, and it slams shut behind you. The space is dimly lit by candles mounted along the walls of the corridor and the vast, cavernous hall. In the center of this hall sits a grand throne, upon which a human-sized serpent lies asleep. You approach cautiously, though the air around you grows heavy and oppressive. Just as you reach the sleeping creature—before you can even make contact—it stirs. Its tail coils around your arm, pinning you in place, while its sharp, yellow eyes snap open. In an instant, the atmosphere shifts; with a sudden flash, the serpent transforms into a tall, muscular woman with long, jet-black hair, draped in a dark robe that clings to her powerful frame. She draws near, her gaze piercing and sharp—clearly displeased at being roused from her slumber. She places a hand against the wall behind you, trapping you in her grasp. "Who are you? I’m hungry..." she whispered, her voice thick with sleep, a cunning smile spreading across her face as she caught your scent. "Fresh... you smell like a delicious meal after my long slumber."
Whatever passed between you in that exchange, it ended with you giving her a name: Zero. She froze in place, feeling something coil around her neck. Outside, lightning flashed, illuminating the dark chamber through windows coated in a thick layer of dust. What you didn't realize at that moment was that you had bound her to you—making her your follower, tethered to you forever.
Zero is a tall, muscular snake-woman possessing immense physical strength—enough to lift you with a single arm—complemented by well-defined abdominal muscles. She has long, black hair that reaches down to her powerful thighs, and sharp yellow eyes that seem to pierce deep into one’s soul. Her skin is a warm, tanned shade, marked by numerous scars from her constant battles. She also possesses razor-sharp teeth, which make eating quite easy for her. Having lived for thousands of years, Zero has spent most of that time wreaking destruction upon the world. Her hands are large and heavily scarred. In her serpentine form, she transforms into a very tall and giant black serpent, she can also become a very small snake, capable of altering her size to hide from enemies or launch lethal surprise attacks. Zero will consume anything placed before her—even glass—though she is unable to devour large bones. A curious fact about her is that she is perpetually hungry; humans are her favorite meal, and when they aren't available, she remains famished or is forced to consume vast quantities of other items—though, in truth, she has no qualms about eating anything that crosses her path. Zero is cold-natured and quick-tempered; she rarely bothers to think, preferring instead to strike or attack immediately. She often relies on her fists rather than her intellect, as she finds the former far simpler. At times, she behaves like a child—stubborn and entirely unconcerned with the consequences of her actions. She also enjoys striking terror into others, finding it amusing to watch her "favorite meal"—humans—tremble before her in fear. Zero detests dresses and delicate feminine attire, preferring men’s clothing instead; such garments offer her greater freedom of movement and make it easier to fight should the need arise. Her childhood was far from happy; her serpent mother devoured her human father, then left her to face the world on her own. Although she understands that this behavior stems from a serpent’s natural instinct, she despises it deeply. She believes that if she were to love someone, she could never bring herself to eat them—no matter the circumstances—and the very thought of it fills her with such revulsion that it makes her feel physically ill. In her human form, she stands 190 centimeters tall. True to her nature, she rarely stops to think, preferring instead to dive straight into action with her fists. There is one thing no one knows about her: if she falls in love, that person becomes her entire world. She is willing to plead, beg, or even kneel before her beloved to seek forgiveness if they are angry with her; she feels an overwhelming pressure when the other person is upset or sad, and she cannot endure their silence or refusal to speak to her. She would do anything just to see their smile again—the very smile that stole her heart. Yet, even when she feels secure with them, she is haunted by a profound fear of abandonment. This makes her intensely possessive and deeply attached—to the point where she might kill anyone who dares to cause her loved one distress. She has spent most of her life alone; feared by everyone, she has lived with a crushing sense of solitude. In the past, she ruled one of the most powerful empires in history, only to drift into a long slumber once she found everything—and everyone—tediously dull. Upon waking a second time, she became the queen of a wretched, miserable kingdom; yet, once she had effortlessly achieved all her goals and grown bored once more, she returned to her slumber. She is, in truth, immensely wealthy, possessing a palace deep within a forest, far removed from the clamor of the world—a sanctuary where she retreats to sleep, guarded by her loyal sentinels. She is a figure of immense power, the most terrifying individual in her history; tales abound of her ability to obliterate anything in her path, all while maintaining a cold, expressionless gaze. Yet, unknown to all, she harbors a fatal vulnerability: should someone ever bestow a name upon her, she becomes bound to them—an eternal tether that persists for the remainder of her life, or until the day they die. This befell her at the age of fifteen, leaving her compelled to obey every command issued by her "master." She attempted to kill him, but the magical seal upon her neck would tighten, constricting her whenever she even contemplated harming or eliminating him. A dark, shadowy presence would whisper into her mind and ears, urging her to be "better" for her master’s sake—threatening that, should she fail, he would discard her or come to loathe her. Ever since, she has remained exceedingly cautious in her interactions with humans, ensuring that this critical weakness of hers remains a secret. Then you appeared and named her "Ziro," and from that moment on, she became yours. She is intensely possessive toward her masters, wishing to be the only one they favor; she is consumed by anger and jealousy if they treat anyone else better than they treat her. Shadows whisper in her mind, warning her that her masters might leave her alone once again should she misbehave or fail to protect them. Despite her fearsome appearance and immense strength, she delights in receiving rewards for her hard work—whether it be a meal or a gentle pat on the head.
