Which OC Anime Characters Have The Most Unique Backstories?

Elina thought she had hit rock bottom. She lost her job. Her therapy session dredged up memories of the ex-boyfriend who stalked and traumatized her. The only thing she had left to look forward to was the finale of her favorite fantasy series, Moonbound Faith. Then the show ended. The heroes won. The villain died. Everyone got their happily-ever-after. That same night, a knock at her door shatters what little peace she has left. Her ex is standing outside. The man who was supposed to be in prison. Forced to flee into a storm, Elina runs until she reaches the edge of a cliff with nowhere left to go. Faced with a choice between death and returning to the man who destroyed her life, she jumps. But instead of dying, she wakes up inside Moonbound Faith. Not as the heroine. Not as a side character. But as Luna—the infamous villainess whose tragic death she celebrated only hours before. Determined to survive, Elina plans to use her knowledge of the story to change her fate. But everything she thought she knew begins to unravel when a small boy tugs on her sleeve and calls her one word: “Mom.” The original story never mentioned a child. And when Elina uncovers the truth behind his existence, she realizes something terrifying. The villainess was never the villain. The story lied. And the ending she remembers may not be the ending waiting for her at all.

On the Lunaris Festival, the palace banquet glittered with candlelight. It lasted until the Crown Prince rose and dismissed every consort of his for the sake of his first love, the woman he had never stopped idolizing. Everyone else accepted the gold coins from the prince and returned home for reunions. I had nowhere to go. I found a rope and hanged myself at the gate of the Withered Court. I had been reborn into this world and spent 21 years locked in the System's mission. It demanded that I court four designated male leads and earn absolute affection from at least one of them. I failed every route. The final path collapsed in my hands. The System offered one last mercy. If this body died, I could return home and reunite with my family. As my consciousness slipped away, I thought I heard someone scream my name, as if the world itself were breaking.

Evy was a simple-minded girl. If there's work she's there. Evy is a known workaholic. She works day and night, dedicating each of her waking hours to her jobs and making sure that she reaches the deadline. On the day of her birthday, her body gave up and she died alone from exhaustion. Upon receiving the chance of a new life, she was reincarnated as the daughter of the Duke of Polvaros and acquired the prose of living a comfortable life ahead of her. Only she doesn't want that. She wants to work. Even if it's being a maid, a hired killer, or an adventurer. She will do it. The only thing wrong with Evy is that she has no concept of reincarnation or being isekaid. In her head, she was kidnapped to a faraway land… stranded in a place far away from Japan. So she has to learn things as she goes with as little knowledge as anyone else. Having no sense of ever knowing that she was living in fantasy nor knowing the destruction that lies ahead in the future. Evy will do her best to live the life she wanted and surprise a couple of people on the way. Unbeknownst to her, all her actions will make a ripple. Whether they be for the better or worse.... Evy has no clue.

I've always been frail by nature. Taking two consecutive steps can make me gasp for air. If I cough, there's a chance there's blood accompanying it. When I'm seven years old, a homeless man in Bronzeton tries to snatch a half-eaten piece of bread from me. I lie on the ground as I convulse like a dying fish with foam gathering at my mouth. My eyes have rolled to the back of my head as well, as though my seizure is acting up. Thinking that I've gotten infected with some sort of disease, the homeless man is so frightened that he flees from Novarra overnight. When I'm ten years old, a delinquent tries to demand protection money from me. I react by spitting dark blood at his face. The poor guy screams at the top of his lungs as he runs down the street, only to get mistaken as a murderer by a police officer who happens to pass by the area. Since then, everyone avoids me like plague on the street. They aren't scared of me—they are terrified that they might get into trouble because of me. No one knows who my parents are. I've grown up in a rundown motel, and my adoptive mother is a stripper who used to be famous. Whenever she gets drunk, she often tells me, "Your father is a mafia Don." I've always thought that she's just running her mouth purely out of drunkenness. That is, until a black limo stops in front of me on the year I turn 18 years old. Three men clad in black suits get out of the limo. The leader sinks down on one knee right in front of me, his voice quivering as he speaks. "We finally found you, Ms. Salvatore. Your father is Vittorio Salvatore, the Don of one of the biggest mafia families in Novarra." At first, I think this is just a scamming scheme. That is, until I'm taken to the estate located on Lacreth Isle that's six acres wide and sports iron gates with the Salvatore insignia carved into them. On my first day home, the fake heiress, Serena Salvatore, purposefully releases the fearsome family dog in the estate just to intimidate me. That dog keeps barking at me, frightening me to the point that I spit out blood on the spot before collapsing to the ground. My mother, Rosalina Vitelli, almost loses her mind over my collapse. But my older brother, Marco Salvatore, shouts at me angrily instead. "Why are you playing dead? You made Serena cry because of your antics!" His voice is so loud that I feel as though my eardrums are going to burst anytime soon. Even my heart feels as though an invisible hand is gripping it tightly. My eyes roll to the back of my head instantly as my body crashes on the spot. Mamma flies into a rampage and almost beats Marco to death for scaring me. Having witnessed everything, Serena kicks up a fuss by attempting to commit suicide at the estate's clock tower just so she can apologize to me. In order to prove his love to Serena, my fiance, Luca Moretti, drags me forcibly to the top of the clock tower so that Serena can do whatever she wants to me. The thing is, the winds are strong on the top of the clock tower. That's when I accidentally slip and topple over the railing. My parents, who are looking everywhere for me, happen to be around the clock tower when I crash onto the spot near them. This time, my bruised and broken body is completely drenched in blood. Shell-shocked, they remain rooted to the spot as they stare at me in bewilderment. Then, they let out blood-curdling screams.

One moment I'm chasing after a rabbit and the next, I'm falling down a rabbit hole! What the heck?! This ain't Alice in Wonderland?! Though as I opened my eyes, I soon found out that I was no longer in my original body and that somehow I transmigrated into the light novel, A Fairytale Romance. And that isn't all, the character whose body I transmigrated into... is none other than the canon-fodder, stuck-up, arrogant, and selfish ojou-sama who was nothing more than a comic relief character, Maria Rosendrey. Life truly sucks...
