Just to let you know, this is the first (and maybe only) Knight's & Magic fanfic I will ever make. I am inspired by the anime (although I didn't read the manga/light novel), and I've been thinking of a possible swan song story as a conclusion. This story has OC characters (extraterrestrials), one serving as an ally and the rest being the main antagonists.
The story will be strictly rated M, featuring excessive gore and violence in some scenes, coarse language, one sex scene, and intense/frightening scenes. Will have a mix of action, drama, sci-fi, and horror to the fantasy genre, emotionally devestating moments, and a bittersweet ending.
One thing I have to say, this story's gonna be batshit crazy. Think of it as a mix of the anime, with action elements from Independence Day: Resurgence, intense horror elements from Overlord (2018) and the dark overtones like The Killing Joke; consisting of mechs, magic, destruction, evil aliens, zombie-like mutants, and badass explosions. Throughout the story, it will be gradually darker as the story goes, with the final half of the story being a bit lighter.
Lastly, this story is not intended to ruin the series, it's only intended as a 'what if' storyline as if the whole series were to make a conclusion.
Enjoy.
