Wow, I completely missed that this movie exists and thought you were fucking with us. But no, they seriously did a soldier isekai into Monster Hunter world. How much coke was involved in making such a travesty?

Wait monster hunter the game series or monster hunter international the book series? the books focus on private contracting companies hunting vampires and what not for the government while trying to keep the public from knowing monsters are real, one of my favourite book series so I hope it's the latter

Try Monster Hunt.
