I want to play this game with my friends after exams are over. Was wondering this steamrip was safe. If not then how should I go about downloading this?

For context, I've not read the manga yet(was planning to before the anime announcement). Didn't kagurabachi only release recently? Is this a type of kagurabachi joke that I'm unaware of or is it just plain larping.
