It mixes up the clichés and makes up a decently original story imo. I see potential in this. That said, not sure if the waifus on here are going to be all that attractive, which is fine, just a little sad.
The goddess really said fuck the kids original body, that's gotta be infuriating. Living your life then some goddess of your world rips you out of your body essentially killing you and putting someone else there and there is nothing you can do about it.
Ok so let me get this straight. The author starts out with a fantasy world post-demon-king birth yet unexplained mysteries and a natural magic system, only to immediately replace it with high-school bullies at a cliched supernatural academy with contemporary fantasy monster gates and litRPG dialogue windows? Eat my ass.
