Underworld Sailor Moon Crossover

Elias Vassari was just starting his life—fresh out of college, dreaming of becoming a teacher—when death came without warning. But instead of peace, he wakes up in the chaotic depths of the Underworld, his soul torn from his body and his existence hanging by a thread. To return to the world of the living, Elias must descend through the nine layers of the Underworld, each ruled by a Guardian embodying humanity's darkest emotions. Armed only with his Burden—a weapon forged from his pain, guilt, and deepest regrets—Elias will face monstrous foes, unravel forbidden truths, and battle the most dangerous enemy of all: himself. Time is running out. His stolen body is being used as a vessel for something far worse. And in the Underworld, every step forward comes at the cost of sanity

On that night, as I walked aimlessly through the alleys with tears streaming down my face, I kept mumbling, “I hate my life, I hate my life, I hate my life.” I was so immersed in my self-wallow that I didn't realize how far I had wandered up the mountain until I tripped on a rock and landed on my right knee. “*Hissed* How do I walk back down limping?” I murmured into the silence, unsure of what to do next. Just as I was about to find my way back down, something caught my eye at the top of the mountain, just a few steps away from me. A flower was glowing there, radiant and mysterious, and I couldn't help but feel intrigued by its presence. I limped towards it, ignoring the pain in my knee, my gaze fixed on the flower as if it held the answers to my troubles. As I stepped closer, I heard a rustling noise behind the bushes. “Hello, is someone there?” I called out gently, but deep down, I figured it was just a rabbit or something. My attention remained on the flower, its beauty ethereal, enhanced by the full moon hanging in the sky. Just then, I felt an odd sense of courage wash over me, and I decided to touch the flower. As my fingers made contact, I was unprepared for what happened next: the flower's glow transferred to me, slowly causing it to wither away. “No, no, what did I do?” Panic surged through me as I tried to brush the glow off my body, but instead, it became even more blinding. Suddenly, I felt something leave me, and whoosh—I was lifted off the ground, emitting a fog-like glow as the world around me darkened. “*Gasp* Where am I?” I opened my eyes wide, darting them around in confusion, trying to make sense of everything. “Was it just a dream?” I wondered aloud, but everything looked so familiar; I found myself in my room, yet something felt profoundly different. I stood up, intent on freshening up, but paused when I noticed my fingernails—they were ash-colored and longer than before. I didn’t remember getting a manicure, so what was happening? I pushed those thoughts aside and stripped down to take a quick shower, but that’s when I let out a startled scream. A massive flower tattoo covered my back! “H—how? I didn't do this, right?” Confusion and disbelief washed over me, but beneath it all, a thrill of anticipation began to stir within me. What had transpired? What did it mean for the future? The events of that night felt like a catalyst for something far greater, and I couldn't shake the feeling that my life was about to change in ways I could hardly comprehend.

“I will drag you into an darkest abyss, as you have done to me for your betrayal. It’ll be like an eye for an eye and tooth for an tooth.” Atlas watches him kneeling on the ground with a dagger in his side, blood trickling from his wound. Atlas stands there, leaning against the wall with a nonchalant expression. Atlas stepped away from leaning against the golden statue, and he walked closer to him with a predatory grace, calm and effortless, and Atlas cradled his face with a possessive and clinging hold, and Atlas smiled gleefully, “Let’s make a deal. Belong to me and do everything I say, and I’ll release your brother.” Sebastian never saw this day coming, and he truly regretted saving him on that snowy day. This person isn’t the same youth from before, for vengeance and hatred only remain in his heart. The only thing he can do is appease the man. But this time, he will never give out his heart again. And he will never reveal the real truth behind his betrayal. What’s the point? Sebastian looked at the man before him and resisted the urge to move away from the hand on his face. His eyes remained stoic. In a hard voice, he said, “Fine. I will do what you want; in exchange, let my brother go.” *** Sebastian lives a normal life with his family, but he lives a hidden life. He has a dark secret that he protects at all costs; otherwise, he will be killed for being a monster. He and the rest of his family are vampires, living off blood, but his family, especially his father and mother, don’t feed on humans, for they cling onto morality, hoping not to descend into depravation. Sebastian cherishes his family, and they are both his strength and his weakness. They are the ones who maintain his humanity and keep him in check. But being a vampire comes with a deadly price; he must blend in with the human world, pretending to be a human is an effortless task: calculating and flirtatious is a mask he carries for centuries, playing with the lives of those around as if they’re just a game. His heart never lets anyone in, keeping distance from anyone except for his family, who live and protect each other. On that fateful night, he never thought he could have another emotional connection. A young, feral boy carrying a hunter's knife is surrounded by blood, snow, and dead wolves in the forest. Why does his youthful body carry a grotesque canvas of scars like they tell a gruesome past? Why do his eyes carry a heavy burden that’s too young for a human? Or is he a human in the first place? Soon, he would learn that Atlas carries heavy, dark secrets, where Sebastian had to look for an answer in Atlas’s past and must decide if he’s worth forgiving and protecting. ***

Noah was born into a family of wealth, privilege, and power. A Family that claimed to love him. A Family that claimed to protect him. A family that, when he spoke of the dreams—the strange, impossible dreams of another world—called him Sick. Delusional. They swore it was for his own good when they locked him away. They swore it was to keep him safe when they silenced him, drugged him, tortured him. But Noah remembers. Even as the days slip through his fingers. Even as his memories blur, as faces become strangers, as reality itself warps around him. He remembers the golden light, the endless sky, the feeling that somewhere—somewhere—he once belonged. And when the last of his past begins to slip from his grasp, when he can no longer tell what is real and what is false, he clings to the only thing that still burns inside him. Rage. They took everything from him. His freedom. His mind. His very Name. Now, he will take everything from them.

Power is not taken—it is owed. Lucian Smith was just an ordinary reader, a man who devoured stories of ruthless kings and untouchable mafia dynasties. But when fate grants him a second life, he awakens in the very world he once read about—as Lucian Valenciari, heir to the strongest mafia family in existence. The Valenciari Family, feared as "The Silver Serpents," controls the shadows of Eredia, shaping both the underworld and high society. Their legendary bloodline ability, Sovereign Serpent’s Dominion, bends fate itself. And Lucian? He has inherited a power so overwhelming that even his own family fears what he may become. But strength alone is not enough. In a world ruled by ancient bloodlines, betrayals, and unseen wars, Lucian must outplay rivals, silence enemies, and carve his own throne in a world where the weak are devoured. Because the Valenciari do not beg. They do not bow. They collect their debts. ~~~~~~~~~~~~~~~~~~~~~~ Hey there, dear reader! So, let me tell you—I’ve been working on this story for over a year. That’s 365+ days of writing, rewriting, questioning my life choices, drinking way too much coffee, and staring at my screen like a mafia boss plotting world domination. Every single chapter has been edited, re-edited, and then edited again (because apparently, I enjoy suffering). But why? Because I love this world. I wanted to create something that feels alive—a world where power isn’t just about brute strength but about strategy, deception, and knowing exactly when to strike. And of course, a main character who’s not just strong but calculating, charismatic, and a little terrifying. So, if you’re here for mafia intrigue, deadly power struggles, and a protagonist who always plays the long game, you’re in the right place. Buckle up, because the Silver Serpent always collects his debts—and this story is just getting started. Enjoy, and thanks for reading! —Aaron_Arkwright

The grip he has on my hair loosens as he kneads my nipple between his thumb and index finger. My back is now arching forward, leaning into his touch. I want more. He chuckles in response. His breath coats my neck as he does so. "So needy," he taunts me before he removes his hands from my body. I'm ready to protest against the loss of his touch, but before I can, he grips my shoulders in his warm palms, pushing me back onto the sheets and pillows. I shudder in delight. Our eyes connect, and I feel the fire in my body ignite from how he looks at me. His eyes scan my body for a fleeting moment before he grabs the blanket and pulls it up.  "Spread your legs," he demands. His tone was low and husky. I comply, and he rewards me with a grin that says everything he doesn't need to say out loud. "You're perfect," he says in a whisper as he crawls further onto the bed between my legs. He's hovering over me. One hand cups my face as he leans down, resting his other arm on his elbow next to my face.  My fingers are tracing the outline of his toned abs. Enjoying the goosebumps rippling across his skin as a result. I watch as he closes his eyes, taking a moment to absorb this feeling before closing the gap between our lips. His lips are delicious.  "Mmm," I hummed against his lips. He deepens the kiss, sliding his tongue in my mouth. Our tongues collided like a happy accident. I slide my fingers up his chest and wrap my hands around the back of his neck, pulling him closer to me. He groans in response, vibrating against my lips. His dick is hard and pressed against my core, making it throb with need.  --------------- Phoenix was adopted by humans as a baby.
