Mythos, Book One

You follow the story of the main character – which you may choose to be male or female – as they learn of the mysterious death of their ex-girlfriend, Lisa Harrison. Soon, the main character finds themselves fumbling through the hidden society of supernatural beings that lurk in plain sight. Some are very much like the legends suggest, while others couldn’t be further from what one would expect.
Will our hero piece together the puzzle behind the murder of Lisa Harrison, or will they be consumed by new attention they’ve brought upon themselves?

Solving a murder while also discovering that there's a whole supernatural world out there is quite a feat, but thankfully you'll have some help! A rowdy country-girl childhood friend, a tricky fae, and even a police detective are amongst your allies as you unravel the threads.
Of course... who's to say that these accomplices aren't also suspects?

Why is the word "adult" in quotes, up there?
Simply put, "Mythos, Book One" does have some sexual content in it. Five lovely ladies are helping you with your investigation, and as you investigate Lisa's death, you may find yourself becoming romantically entangled with one (or all!) of them. If that happens, things can get very spicy, very quickly. However, you can also choose to completely forgo any romantic encounters at all, choosing to instead focus only on the detective work. Whichever you pick, the core story of the murder investigation will be unaffected by whatever amorous side quests you choose to partake in. Mythos is, first and foremost, a mystery visual novel. There's just some naughty bits thrown in if that's the sort of thing you're into.

And for those of you who want the romance without the naughtiness (or if you plan to stream the game), there's a toggle that lets you skip right past any of the NSFW bits, even if you do choose to get closer to one of the ladies.
