[h1]Story - Content[/h1] Mythos, Book One begins with our protagonist (who can be chosen to be male or female; the only difference during the game session will be intimate scenes and some dialogues and the surname) getting questioned by Agent 8699 about their name and nickname, and while the question is being held, you can find a donut on the desk a little blurred out.

About This Game

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.

Overall I would say this is a good mystery story to follow. As the developer said it is based upon the book they wrote, so the erotic scenes were added to bring it home to the audience; i.e. they are not the focus of the story. Which also means they are not around every corner--few. Whereas some VN you can't follow the stories because of all the erotic scenes get in the way. The author has a nice broken 4th wall approach, provides hints throughout the story (make sure you look at the book) and I was able to use the clues to discover the murder without resorting to constant rolling back to find the correct one. That brings me up to my main sour point, the achievements. I applaud that they have gone outside the box to obtain achievements, but in reality only about 20% can be found without using the guide. It requires a lot of rolling back, replaying scenes after the game is over and while I was able to get 75% completion, I am just tired and don't want to keep restarting the game. I pref...
The game was fine. I liked the who done it aspects and how the game shows you various endings. I don't like most the character models, I thought they were a bit ugly. Not a bad game but, only buy on a sale.
Fun well written story with a complicated plot and quirky characters. This would be enjoyable even without the sex scenes. Originally planned to be a female protagonist but now you can play as a woman or man. I played through the first time playing Kylie and then the second time as Kyle. Definitely worth it to play both paths.
