Visual novel presented as a corporate training tool where the story of the characters we are following seems very normal until it begins to drift off the rails, all illustrated with that kind of stock photo
You know the kind
Take the story to some severely strange places, or a murder mystery, or horror. But never ever break from the corporate training style. And commit to the bit and never wink at the audience, even in the itch description or whatever. It's a training tool. That's it.
