The World Ender of My Little Pony

If a soul from a dark world, after enduring endless torment, arrives in this half-utopian world, can it return to where it began and reclaim the heart that once made it a hero? The protagonist is essentially a container for energy. Their changing forms are simply different bodies needed to wield energy of different kinds. [Likely multiple female leads (the early story focuses on character growth, and I haven't decided on the romance yet)] + [Not invincible] + [Meat-eater] + [A little dark, but not much] + [More everyday life] + [May be OOC (the author is catching up on anime while writing and is worried later episodes will pull the rug out from under the story) (the author may also proactively revise plots and characterizations they aren't happy with)] + [There may be typos, I'm sprawled out] [Feel free to share suggestions. The author will keep an eye out. I hope you'll nudge me to update more often; I need a little motivation, sprawled out] [The author is a bit of a late-night manic, so don't be surprised if you come across strange bonus chapters or comments] [The early chapters are being rewritten. I'm planning to revise and rewrite chapters 7–18, but lately I've had almost no inspiration, so progress has been slow. Please bear with me. I'll revise the other chapters as needed, too.] [This book has become a mountain of spaghetti code. The fact that it runs at all is a miracle. Some chapters aren't very good, so I recommend skipping them outright. The author has no idea how to fix them anymore. Stares at the sky. After all, everyone has days when they're out of sorts or in a bad mood.]
