How Do Anime OCs Enhance Cross-Fandom Fanfiction Plots?

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.

As a reader, we can fall in love with a Fictional Character. The words that the author use to define the physical attribute makes us readers fall in love with that character. Same as Amira Madrigal, who's deeply in love with a fictional character named Zeke Alejandro from a book that she always read, the title "Unexpected Love Story". Zeke is a bad boy and an arrogant campus prince who's written to fell in love with Krisha Fajardo, the female lead character of the story. Unfortunately, Amira hasn't read the book completely because her professor caught her reading the book while his teaching. An unknown sender gives her a link to a site where she could continue to read the next part of the story. She doesn't know that this will be the way for her to enter another world. Another dimension. To meet her Love. Zeke Alejandro, the fictional character inside the book. Could she also be the main character of the story she accidentally went into? Or would be the antagonist to the main character that she always imagined to be her? How will the story run?? How will the story end??

I woke up inside a novel, and not even as an important character. I became a pretty background extra in a smut novel. My brother, however, was the only normal person in the entire story. His character setting was the one man the soft, delicate heroine could never win over. He was the cold, unattainable Prince Charming she could never conquer. When the heroine cried and confessed her love, he was studying. When she offered him her whole heart and body, he was busy starting a company. When she spiraled into scandals and nightlife, he was already a billionaire, calm and untouchable. I thought he would live a quiet, ascetic life forever. Until one night, I walked in on him at midnight… holding a piece of clothing I recognized all too well, murmuring a name over and over, a name so familiar that my scalp tingled.

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.

On the day I decide to quit the game, multiple comments suddenly streak across my vision. "Great news! The female supporting lead is finally quitting the game!" "Stacy no longer has to worry about getting exposed for using the supporting lead's game account to get into online relationships with others!" "Stacy is really smart! Every time she uses the supporting leads account, she always uses the in-game voice chat function! That supporting lead has no idea that Stacy has been doing this behind her back!" "Wow, Stacy really is blessed to have reeled in such amazing men!" "I can't believe she used the female supporting lead's max-level account to flirt with four of the best players on the server!" "At 2:00 pm later, she'll be meeting her first target, Lewis Johnes, the cold and aloof campus heartthrob, at Riche Cafe!' "Tomorrow, Stacy will be meeting the best assassin in person. The day after that, she'll meet the rich scion who's also ranked second on the list! She really is amazing with her time management skills!" The "Stacy" that the comments mention is Stacy White, my roommate. She actually impersonated me to flirt with four top-tier players on the server, huh? More comments streak across my vision once again. "Why isn't Heather leaving right now? Lewis is already waiting for Stacy!" "This is their first sweet date as a couple! Oh gosh, I can't wait to see it unfold!" I turn to look at Stacy, who's touching up her makeup in front of the vanity mirror. Only then do I understand that I'm the female supporting lead the comments are talking about. A small smile appears on my face. Since Stacy is impersonating me to become a Casanova, then it's not wrong of me to attend those meetings and reap the reverse harem she has prepared for me, right?
