How Do Anime Crossovers Impact Manga Sales?

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.
