[Crossover] I Just Won't Die

To erase the monster inside my body, I kept trying to kill myself, but every attempt failed.

As for why, I have no idea.

I lost all my memories from the year after that. When I woke up, I found myself lying in a bathtub full of bloody water, and my heart nearly stopped. I cleaned the bathroom as hard as I could so Mom wouldn't find out. Then, on the back of the toilet tank lid, I felt a sticky note firmly attached with tape.

"There's a monster living inside my body."

That's what it said.

1. This is an all-original-character story written for practice and personal enjoyment, as well as to vent my feelings. The logic may not always be airtight, so please bear with me.

The protagonist is a naturally gifted outlier, with an ability similar to [What Is Love]. Anyone who observes and interacts with them develops a sense of familiarity and dependence, but the protagonist cannot control whether the effect on those people is positive or negative.

2. Romance is not the main plot. The characters remain enemies even while having feelings for each other.

3. Some timelines have been heavily altered. Please treat them as parallel universes.

4. For now, the world is a crossover of K, Detective Conan, The Prince of Tennis, Bungo Stray Dogs, and Jujutsu Kaisen. More works may be incorporated later to round things out. Since there are so many crossovers, some settings may be mishandled or overlooked. Feedback is welcome.
