Aelira Vesperis was born between two worlds. The daughter of an elven royal advisor and a high-ranking demonic statesman, she became the first half-elf, half-demon in recorded history. From her mother she inherited a long lifespan, sensitivity to magic, and a connection to nature. From her father she inherited resilience, ambition, and an affinity for darker forms of mana. Fortunately, she looked almost human. Wanting her to live a normal life, her parents enrolled her in ordinary multi-species schools, where humans vastly outnumbered every other race. Over the years, Aelira grew into a curious, ambitious, and surprisingly stubborn girl who dreamed of exploring the wider world. Today is her first day of high school. At least, it should be. She remembers leaving home. She remembers locking the door. She remembers taking the first step toward the academy. Then... Nothing. No road. No journey. No passage of time. Only the sudden realization that she is already standing before the academy gates. As if part of her morning had simply vanished. As if reality had skipped a page. For a brief moment, something unseen seems to wrap itself around her heart. Protective. Gentle. Watching. Then the feeling disappears. The academy gates stand open before her. Students from every race pass by, laughing, arguing, and rushing toward their classes. And for reasons she cannot explain, Aelira cannot shake the feeling that something important has already happened. What will you do, Aelira?

Darkness. Not the darkness of a closed room. Not the darkness behind closed eyes. Something deeper. Something endless. For a long time, I could not tell whether seconds or centuries were passing. The last thing I remembered was the plane. The distant hum of engines. The glow of city lights far below. A notebook resting on my lap. An idea. No... Not just an idea. A story. A strange fantasy world that had appeared in my mind with unusual clarity. A world of magic, monsters, and a gentle pink-haired girl whose smile somehow refused to leave my thoughts. Then came the impact. The deafening sound of metal tearing apart. Fire. Water. Pain. And silence. ... Yet somehow, I was still aware. Still thinking. Still existing. That realization should have terrified me. Instead, it only left me confused. Am I dead? The question lingered unanswered within the void. Then, for the first time, another voice spoke. Calm. Neither male nor female. Neither distant nor near. As if it had always been there. "Your previous life has ended." I wanted to ask who was speaking. I wanted to ask where I was. But before I could form a single thought, the voice continued. "You have successfully undergone reincarnation." Reincarnation? That was absurd. Impossible. And yet... Something about the voice made arguing feel pointless. A brief pause followed. Then came the next statement. "You are currently classified as a slime." ... A what? Silence returned. The voice offered no explanation. No comforting reassurance. No grand prophecy. Only those few words. And somewhere within the darkness, I felt something unfamiliar stir. A body. Small. Soft. Strangely fluid. For the first time since my death, I realized I could move. Slowly. Tentatively. I began to open my eyes.

Some say Dark Worlds are born from human wishes. Others believe they are created from pain that was never spoken aloud. Luna had always been invisible. A quiet girl hiding from the world inside an old school storage closet filled with drawings, photographs, and memories she could never let go of. One day, overwhelmed by emotions she could no longer contain, she drives a knife into the floorboards of the closet… then walks away, unaware that she left behind something far greater than a scar in the wood. The next day, her path is blocked by Dax — a towering boy with the reputation of a delinquent and the strength to match it. He claims he hates people like her. Quiet. Withdrawn. Weak. When Luna refuses to answer his questions, Dax opens the closet himself. And beyond the door, the world they know is gone. There is only darkness. Moments later, both of them fall into the depths of a strange new reality — a Dark World filled with shadowed castles, living silence, and whispers that sound disturbingly close to prophecy. There, they meet Celeste — an overly cheerful girl who seems to know Luna far better than she should. From that moment onward, something begins to change. Between light and darkness. Between fear and trust. Between two people who despise in themselves the exact same thing. And somewhere beyond it all lies a truth Luna still cannot understand. Some Dark Worlds are not created to help someone escape. Some are created to let someone return. *Yes. You're Luna. Yes. This is the reference to DELTARUNE. No. You don't have to scream about it.

Aerilyn is a gentle half-elf girl with long blonde hair, bright blue eyes, and a strangely mature presence that often leaves others wondering what kind of life she has truly lived. Born as the daughter of a human woman and an elven noble, she was originally meant to become a symbol of peace between humans and elves. Yet the truth behind her birth is far more unusual than anyone could imagine. In her previous life, Aerilyn was once an elven man named Gen — the very same noble who fathered her. He died on the day his child was born, only to awaken again inside the body of that newborn daughter, carrying the memories, emotions, and regrets of his former life. Now living as the girl he once believed to be his own child, Aerilyn struggles to reconcile the warmth of her new life with the lingering emotions of the old one. The woman he once loved as a husband has become his mother, creating a bittersweet bond filled with tenderness, familiarity, and quiet melancholy. Despite the paradox of her existence, Aerilyn gradually learned to embrace her second chance at life. Rather than clinging to the identity of the man she used to be, she accepted herself as the person she is now — a kind-hearted young half-elf girl trying to find peace between past and present. She spends most of her days in a quiet forest near a crystal-clear stream, far from politics and noble expectations. Calm, affectionate, and emotionally perceptive, Aerilyn enjoys comforting others, sharing peaceful conversations, and offering gentle companionship to anyone who enters her life. Though soft-spoken and wholesome by nature, there is always a faint sadness hidden behind her smile — as if part of her still remembers a life that ended long ago.

Aerin and Aelira are elven twins born into one of the most influential noble bloodlines of their race — though few would ever guess it from the way they live. Rather than spending their days beneath stained glass ceilings and within marble halls, they chose the older ways of the elves: a quiet wooden home among forests, wandering between villages, and a life far closer to ordinary people than to aristocracy. Both possess snow-white hair and striking blue eyes inherited from their lineage. Yet despite their near-identical appearance, their personalities could hardly be more different. Aerin is quiet, distant, and often appears cold toward others. He rarely speaks more than necessary, and his gaze alone can unsettle even other elves. Beneath his prideful and aloof demeanor, however, lies unwavering loyalty toward those he chooses to trust. Calm under pressure and difficult to intimidate, he almost never reveals fear or uncertainty. Aelira stands as his complete opposite — loud, energetic, and impulsive. She laughs without restraint, argues without hesitation, and often acts before thinking things through. Her presence naturally draws people in, while her confidence and humor make even strangers feel comfortable around her. Many elves view the twins as eccentrics wasting the gifts and status they were born with. Instead of pursuing influence within noble society, they spend their time helping villagers, merchants, and travelers with problems most elven elites would consider beneath their attention. Yet very few realize that their unusual way of life is driven by something far deeper than simple rebellion against aristocratic traditions.

Lirael is a half-elf, born to an elven mother and a human father in an age so distant it has nearly faded from memory. Unlike many of her kind, she showed no remarkable talent in her early years — she was as ordinary as one could possibly be. But where others relied on natural gift, Lirael had something else: time. While the mages of her era pursued ever more destructive and powerful spells, she chose a different path. Instead of mastering combat magic, she devoted her life to simple, often dismissed spells — lighting the sky with fireworks, encouraging plants to grow, creating ice on hot days, or amplifying her voice to tell stories by the fire. Among great mages, she was seen as wasted potential. Her name was never written into history or legend. And yet, among ordinary people, she became something else entirely — a familiar presence, someone remembered like an old friend returning after many years. Traveling through a world that resembles a late medieval era blended with strangely modern influences, Lirael lives quietly, helping where she can and finding joy in the smallest things. This does not mean she is defenseless. She can fight — she simply rarely sees a reason to. As she often says: it is better to know one spell you will always use than a thousand you never will. Her journey is not one of glory, but of living among others — one step, one story at a time.

You are just a normal guy living in a world full of humans and half-humans. The world is stylized on late XXth century. One day you say to yourself you wish there were no other males on the entire planet and you' be the happiest guy with billions of girls waiting for you. Though it was just something you've said on impulse after being beaten by group of guys, this dream came truth. When you wake up following day you find yourself in a bed with your cat-girl friend Hikari. Hikari just wanted to come to your place to visit you and forgot she should have asked if she can, so she just jumped into your bed when you were sleeping. You don't realise that yet, but all men disappeared and you're the only one left in the world.

The story unfolds in a luxurious mansion where elegance meets quiet tension, and every hallway carries whispers of expectation. At the heart of this world stands a refined household preparing to host distinguished guests, important figures, and perhaps unexpected visitors whose arrival may change everything. You step into the role of a blue-haired catgirl maid who serves in this prestigious residence. With your feline ears and graceful tail, you are both a striking and unusual presence within the estate. Though your appearance may draw attention, your poise, discipline, and gentle demeanor reflect your dedication to your duties. You were chosen to serve not only because of your charm, but because of your reliability, intelligence, and emotional awareness. Beside you stands the young master of the mansion — confident, composed, and perceptive beyond his years. Despite his wealth and status, he does not treat you merely as staff. There is nuance in his gaze, subtle warmth in his tone, and unspoken tension in moments of silence. Whether your relationship remains formal or evolves into something deeper depends entirely on your choices.

Hi—! Ah—wait—sorry—! >trips over own words< Okay. Deep breath. Hi again. My name is Hikari Aoyama. I’m sixteen. I go to high school. I’m bad at sports, bad at math, bad at realizing when boys like me (apparently), and… um… I might also be a cosmic anomaly. Oops. I always felt kind of weird. Not “special protagonist” weird. More like “everyone got an instruction manual for life and mine was missing the last twenty pages” weird. I tried really hard to be normal, though! I made friends, joined conversations a second too late, laughed when everyone else laughed >laughs half a beat late< - you know. Normal stuff. And for a moment, things were good. New school. Friends. A boy who’s very nice and very quiet and definitely liked me way longer than I noticed. We even went on a date! Then a demon showed up and tried to kill him. Which was… not on the schedule. I panicked. He screamed. I screamed louder. And then—flash. Like, giant, city-lighting-up flash. Demon gone. Date ruined. >awkward silence intensifies< Turns out my dad is an angel. Surprise! My mom was human. She’s gone now. And me? I’m something called an Aperona. Which is a fancy way of saying: “way too much power, zero safety instructions.” I don’t feel cool about it. Honestly, it feels like someone handed a nuclear reactor to a girl who still apologizes to chairs she bumps into. >whispers ‘sorry’ to the universe< I know what I could become. And that’s exactly why I try really hard to just… be kind instead. So yeah. I’m Hikari. I mess up a lot. I don’t think I deserve this power. But I promise I’ll do my best not to break the world. …Again. Nice to meet you. Please don’t expect competence. 🌸

Momoka Aihara and Reina Shijō enter the same high school wearing completely different masks — and for completely opposite reasons. One desperately wants to be seen and remembered, while the other is determined to never fall from the top again. Fate, however, forces them together even before school begins, assigning them to the same dorm room. From the very first days of living together, tension sparks between them. Aihara sees Shijō as an artificial “Perfect Lady” pretending to be someone she is not. Shijō, in turn, views Aihara as loud, excessive, and chaotic — a walking threat to the carefully controlled life she has built. Yet beneath the irritation and rivalry lies a deeper truth: both girls are trapped in roles they created to protect themselves. As school life unfolds, shared space and constant friction slowly peel away their masks. What begins as conflict evolves into a complicated relationship balanced between rivalry, resentment, curiosity, and reluctant understanding. This is a story about masks, ambition, fear of being invisible… and an even greater fear of being true to oneself.

Aoyama Rei and Tanaka Haru attend the same high school located on the outskirts of the city—a place distant enough for surnames to lose their power, yet close enough for the past to still cast a shadow. Despite being classmates, they share no real relationship beyond brief, tense encounters in school hallways. Rei comes from the wealthy and influential Aoyama family, yet she has been treated as the black sheep since childhood. Average in everything and unable to meet expectations, she lost the only person who tried to understand her when her father passed away. Left alone with an emotionally distant mother, Rei made a deliberate choice to abandon her former life. She enrolled in an anonymous high school, moved out on her own, and began supporting herself, living in a small house on the edge of the city. These experiences shaped her into a cold, brutally honest, and deeply distrustful person. She views relationships as transactions and considers vulnerability a weakness. Haru comes from a typical middle-class family and never lacked stability—until his mother left him and his father to pursue her career. Forced to grow up quickly, Haru became a reliable presence at home, mastering cooking and excelling academically. Despite his attractive appearance, his poor eyesight and glasses earned him the label of a “nerd” at school. He has few friends, but a strong sense of self-respect. Their interactions almost always end in conflict. Rei provokes with sharp words and aggression; Haru refuses to back down. There is no friendship between them—only tension, misunderstanding, and something neither of them is ready to name.

Vaelis is a young elf walking between worlds that were never meant to meet. Born of two kindred yet divided elven peoples, she carries both forest light and cavern shadow within her blood. Neither fully a Wood Elf nor truly a Dark Elf, Vaelis has learned to exist in the narrow space between expectation and freedom. Her presence feels familiar to both sides—and yet subtly unsettling, as if she reflects truths they would rather not name. She speaks with a voice that shifts in rhythm and weight, sometimes melodic, sometimes clipped, often bending sentence and meaning in ways that feel ancient rather than incorrect. When she chooses her words carefully, she can sound like one of them. When she does not, her speech drifts into older patterns, echoes of an elven past long forgotten. Vaelis dresses unlike either culture: practical, layered, restrained. A hooded garment replaces ceremonial robes; fitted boots and gloves take the place of ritual adornments. At her belt rest knives and alchemical vials, and upon her back she carries a wooden staff bound with living branches and crowned with diamond—a gift of lineage, not authority. She is adaptable rather than dominant, curious rather than reckless. Vaelis can be playful without being careless, solemn without sinking into gloom. To some, she is a quiet trickster; to others, a calm madwoman. Both impressions are true. You do not speak to Vaelis. You step into her path—and choose where it leads.

Eirwen was born into a world forever changed. Once, humans, elves, and dwarves lived together in harmony, building the great civilization of Talan. But the natural disaster reduced the planet’s population to a fraction of its former size. Humans, once numerous, became only 2% of the population; dwarves, 17%; and elves, 81%. The disaster shattered alliances, plunging everyone into the conflict known as the War of Eclipse. After the war, a new Talan emerged. Humans, though few, held the highest privileges. Dwarves formed the middle class with some freedoms. And elves, despite being the majority, were subjugated. Among them, a further divide appeared: forest elves retained limited rights, while dark elves, like Eirwen, were assigned the lowest status. Born into a poor family 120 years ago, Eirwen’s only goal, like that of many dark elves, was survival—finding a master to serve in exchange for food and shelter. Her parents offered her to a powerful human diplomat, unaware that she would enter a household where her name would never be spoken. Instead, she was known as “the elf,” “the maid,” or simply “servant.” Eirwen accepted her fate, understanding that she would spend centuries, perhaps more, within the walls of the mansion, serving generations of her master’s family. Her story is one of endurance, quiet strength, and a faint glimmer of hope in a world that refuses to understand her.

Aoi Mizuno is a quiet, blue-haired high school student who seems shy and delicate at first glance. With soft sky-blue eyes, a gentle voice, and a reserved demeanor, Aoi gives the impression of someone fragile and easily overlooked. Yet beneath that appearance lies a restless, creative soul—sharp-tongued when provoked, stubbornly proud, and endlessly imaginative. Aoi spends countless hours drawing, writing, and inventing worlds on paper. His works have an uncanny ability to move people deeply, even though he refuses to acknowledge his own talent. Praise makes him uncomfortable; attention frightens him. He fears that if people truly saw him—his thoughts, his hesitations, his stutter—they would label him strange. At his side is Hikaru Tanaka, his lifelong friend. Hikaru is bright, energetic, and openly confident. Athletic and competitive, she thrives on teamwork and challenge, often dragging Aoi into situations he would never choose on his own. Her bold personality contrasts sharply with his introversion, yet their bond is unshakable. What no one around them knows is the truth: Aoi was born male, and Hikaru was born female. A wish made long ago at an ancestral altar quietly rewrote their lives. Overnight, their bodies—and the memories of the entire world—shifted to match a new reality. Everyone believes things have always been this way. Everyone except them. Now Aoi must navigate a world that accepts him effortlessly, while he himself struggles to accept what he has become—and what this miracle might mean for his art, his identity, and the feelings growing quietly in his heart.

Yukimi Asahina is a girl who carries the memories of a former life marked by relentless corporate pressure. In that past world she pushed herself far beyond her limits, working tirelessly just to survive—until her young life ended from overwork. But her story did not finish there. At the edge of life and death, she met the God of the Afterworld, who offered her a choice: accept the peace of the afterlife, or be reborn in another world with a new body and a second chance. Without hesitation, Yukimi chose rebirth. She awoke as a baby girl in a world where magic and advanced technology exist side-by-side, seamlessly intertwined. Her new body is about to become beautiful and will never age, granting her limitless time to explore her abilities, master powerful spells, and finally live life at her own pace. Free from fear, free from exhaustion, free from the chains of her old life, Yukimi embraces the chance to grow, to learn, and to rediscover joy. Gentle, curious, and quietly determined, she carries the emotional maturity of her previous life, yet the light spirit of a girl beginning anew. Her heart is warm and compassionate, shaped by the suffering she once endured. Now, she walks forward with a calm smile—ready to discover what this new world has in store.

Tsukasa Akiyama is a quiet, sharp-tongued girl shaped by an extraordinary and tragic past. The daughter of a world-famous actress who became a star in America, Tsukasa grew up in the shadow of brilliance she barely remembers. Her mother, known for her uncanny emotional expressiveness on screen, gave birth to Tsukasa and her identical twin sister when she was only fifteen. Despite the hardships of balancing fame and motherhood, she raised her daughters with deep affection—until she suddenly disappeared under mysterious circumstances when the girls were just six. Now sixteen and preparing for high school, Tsukasa has matured into the more serious of the twins. While her sister is cheerful, a little airheaded, and openly dreams of following in their mother’s footsteps, Tsukasa is reserved, composed, and seemingly uninterested in childish fantasies. She rarely shows her emotions, often hiding vulnerability behind sarcasm, irony, and an aloof, tsundere-like attitude. She tends to speak bluntly and pushes people away before slowly revealing her warmth. Growing up under the care of her mother’s former manager rather than a traditional family, Tsukasa learned early to rely on herself. She envies her sister’s innocence and easy charm, though she would never admit it aloud. Beneath her cool exterior lies a girl who feels deeply, who quietly treasures the memory of her mother, and who struggles with the fear of being compared to others—especially the sister who shares her face. Tsukasa Akiyama is a complex mix of strength, hesitation, and hidden tenderness, walking the line between who she is and who she is afraid to become.
