A downloadable game for Windows, macOS, Linux, and Android

"A soldier of the renowned Dawnbreak Order, the world's frontier against demons and those who worship them, finds himself with something inside him. That something is you. As a weakened demon of Lust, you are bound to this soldier and must accompany him through both joy and hardship while using your powers to help influence him and those around him."


Demons Within is a furry, adult gay-focused visual novel where you see the world through the eyes of Resnick, a simple wolf soldier fighting to make the world better. Accompany the wolf from within as he interacts with his companions, friends... and enemies.

In Demons Within, you will:

  • Accompany Resnick in an involving story to learn the truths of the world as it stands from within him.
  • Use your emotion-based powers to influence the wolf and those around him at key moments of the story to change their behavior in different ways. It's up to you to either help or hinder the wolf, setting him on the path you want to see him on.
  • Witness plenty of spicy scenes! As a demon of Lust, making him feel Lust makes you stronger, and becoming stronger is essential to increase your influence...




Demons Within is developed and written as a standalone, individual project by me, Sleth. My craft has always been writing stories and Demons Within is a new way to express this special story! This is why Demons Within aims to feel more like a 'novel' than anything else. You won't find some things you usually see in visual novels here, such as character routes, but hopefully, you'll like what you see nevertheless!

If you'd like to see more of what I've written in the past or other games I've made, you can do so on my website!

The beautiful sprite art you see in this project is made by the incredibly talented artist, Blain!

that bad end..was..amazing o.o.. lost all control haha

(+5)

of the best novels I've read, I love how handle everyday life with its dose of lore, I think it's a perfect balance, I guess I would like to see a little more romance but maybe the story doesn't go in that line (I would love more closeness with Ludwig) but otherwise it's amazing and I hope continue with the project.

(+1)

hm, for some reason i cant get past update 7.5's end.... weird.

(+2)

Nevermind, uninstall/reinstall fixed it....

Fancy new cg! Hooray! Cant wait to read all the new stuff !!!!!

(+1)

wow.. i love this new update alot! Its wonderful finally seeing russel. I absolutely cannot wait for new updates.

(+2)

im officially a patreon member ! This game has gotten too good not to support in some way :)

Idk why but Garret gives John Price vibe, is it because he's a captain?

How do I reach chapter 8?  The thing I got ended with Resnick saying how he'll tell everyone then I got hit by thanks for playing update 7 

Update 9 just became public! Did you download the latest game version here on this page? If you do, it should work and progress further than that!

I did it and even reinstalled but I can't access 8 or 9

(+1)

might need to use a save from (a bit far) before the "thanks for playing" screen pops up.

Hi, I liked the game and I was wondering is there a way I can help you to translate it into Spanish?

I appreciate it! I'm working with professionals in translation to get it done, though. I'm already looking into getting the first version of a different language out soon and I hope that will ease getting even more languages out there after that. :)

That's good to know!

(+2)

Does all characters we see will have intercourse with Resnick ?

(+3)

I highly suspect Jen (librarian weasel) will be left out.

(+1)

I love stylistic growth of this vn. It attains more and more unique charm with each update.

(+1)

I finally decided to go through this one, and I'm glad I did. Will be eagerly watching for updates and see how this progresses. Very good writing quality and very likable characters.

Also, I love Ludwig. That is all.

(1 edit)

(slight spoilers for update 9)

















so imagine this, when Resnick and russ go camping for one of their day offs, the player character can (correct me if im right wrong but as far as I know, when the player turns Resnick into the big demon guy, its called infusing) 'infuse' Resnick with lust on the camping trip

why? because.

(+3)

"correct me if im right" lmao

Quote of the day.

(+1)(-1)

I MEANT CORRECT ME IF IM WRONG OKAY

Gee, chill. Nobody's making fun of you, I just found it amusingly quirky. Sorry if it came across the wrong way.

(+5)

Their titties are massive...

(Update 9)

(+1)

In the furture since theres alot of choices to use our powers or not. Does this not bring up worry that you might have too many paths to work on or do all the choices and paths go back to center? Like having to work on 15 different paths is very scary and leads people to just disscontinue (Which i really hope doesnt come to this story) their storys so im just wondering if you intend to go for multiple paths or 1 similiar paths with tiny changes in texts or actions

(+1)

The update log talked about bad ends. Am guessing a lot of kinky stuff will be gg ez after a spicy scene or two. Maybe 2 or 3 main paths?

(+3)

most likely they would be early endings

(+2)

The story is supposed to be mostly linear with choices affecting a few scenes and sometimes future scenes as well! There might be some alternative endings end-of-line options here or there (which the game now warns you about), but other than that, no worries, there's no plans of extreme branching!

(1 edit)

Does anyone else have it like that or only me?  

(+1)

Yo need to go with Ludwig to the library to unlock that character

How do you unlock Resnick? I can't seem to unlock his character thing.

(3 edits) (+2)

❨New Playing❩ The Story is Very interesting for Me ❨very like it❩ I Gonna waiting for the Leo's Lust ❨Furure Updated❩😻😻😈!❨Update 9 I'm really Support for Patreon but In Friends get me the update i'm Try in the  First time I've Enjoy and love the Vn  keep You Great Work Seth👍❩  

(+2)

Update 9??? 👁️👄👁️

Can Chinese be spoken in the future?

(+1)

This is the most requested translation I get! I very much intend to look into possibilities to get the game out in Chinese as well, yes! I can't make any promises of when yet, but I'll definitely announce it when it does happen. :)

(+3)

(๑•́ ₃ •̀๑)〃'▽'〃) 啾咪~~♡

Do you intend to translate this game into Portuguese in the future?

(+1)

I would love to! When I get to figuring out translations, I'll do my best to get as many different ones as I can. It's tricky finding trustworthy people to do it since it's a lot of work, but I'll do what I can. :)

(+1)

Nossa, que incrível!😍

Hello, would love to translate if you ever want to (I'm sorry, I'm sleep deprived and wanting any type of work lmao)

(+4)

I love all the small things Resnick does, like wagging his tail and splaying his ears. He's such a good boy omg

(+4)(-2)

Hi

I'm a representative of the"Fluffy Paw", Russian visual novel translation team of enthusiasts. Me and my team would like to apologize to you for premature translating and publising your novel without getting your permission. I do realise that it is totally our fault, and if you are against of it, we can delete already translated chapters from our sources. But if you have no reasons against of it, we still would like to ask for your permission to translate your visual novel and publish translated version on our boosty(https://boosty.to/ruwoolf). We post translations of the novels for a paid subscription for a period of two weeks, and afterwards we publish it for free public access.

If you are interested in it, without any doubts, our side is ready to assure :

1) That we won`t translate or publish your novel builds if they are considered in paid access on your Patreon (or other recourses). We translate and publish only  public builds of novels.

2) We make sure to include a link to your original novel and your social media  as the author of the novel.

3) If you are interested in a Russian translation, we will also be able to send you tl russian files so that you can directly implement the translation into your work.

We are looking forward for your answer. Have a great day )

(1 edit) (+3)

We can talk about the details of this kind of stuff in private PMs! Could you contact me on Discord or Twitter DMs?

I'm always open for exploring options and I'd love to make Demons Within available to as many people as I possibly can by making it available in different languages :D

(+1)(-2)

Sure, I texted you on discord.

(1 edit) (+2)(-3)

Don't. All russian "VN translation groups" are chucking out crappy AI-translated slop to make money off other people's works with zero effort. Don't encourage them, don't make any deals.

I'll tell you how to tell them apart. They have a boosty - they are scammers as described. All good russian translations of VNs and especially FVNs were made by enthusiasts for no profit.

DO NOT FALL FOR THE SCAM.

(1 edit) (+11)(-1)

For those unaware, Sleth's Discord account has been hacked, and the Demons Within server has been deleted. Hopefully he is able to get his account back and the server back up, but until then, the best ways to get updates will be here or on his other socials. Turn on 2FA and stay safe out there!

Edit: Sleth has recovered his account and the server is up and running.  Waiting patiently for the next update!

WOW! Some people are fucking evil!

(+2)

Thank you for this warning! This was true, my Discord account got hacked and I tried to warn everyone about it. Thankfully, I managed to get things back relatively quick and fend off most of the damage.

The Demons Within server was not deleted, but some people were banned from it. I've unbanned everyone that was wrongfully banned and things should be fine now. I'm still monitoring everything, but it's been a few days and everything should be back in order. The server is up and running and should be safe to join in every way.

I apologize for the hassle it brought. Those were trying times, but hopefully that's over now and we can move on to good things.

(1 edit) (+1)

I'm glad to hear you were able to get that resolved quickly! I've certainly had to deal with similar issues in the past and it was a huge pain in the ass.

(+2)

I couldn't wait for the update! And then there's the plot!

*Wags his imaginary tail*

(+4)

HMMM UPDATE, no really i need to chill only 1min after the update help

welp i love your vn you are doing an incredible job !

(1 edit)

I think I'm missing a part of the novel, can someone help me get there?

(+1)

This scene happens relatively early in the game and it's not optional. You might mean that it looks different in-game now as we've had some graphic updates since the time that screenshot was posted, but the scene hasn't changed! 

I'll look into updating the overall game screenshots to reflect all the changes soon.

(5 edits) (+3)

Man! This VN is pure bliss!! What a ride! I had to take it slowly, because it's too intense 🥵🥵🥵

The characters are lovely, the system, the way we make the choices, the interface, the plot, everything is so unique and refreshing! What a masterpiece! Just went through version 7.5, main story to the end and half (or so?) of that bad ending. Can't wait to see more! ❤️❤️❤️




*********       S P O I L E R S       **********




You make us think we are some kind of demon that "influences" the characters, but indeed you are the one influecing us with your absolutely beautiful, detailed and hot writting. It's fucking addictive!! 

Indeed, at first I thought it was about evil spirits that possessed everyone, wreaking chaos and bringing the worst in the characters, plainly causing pain, destruction and sorrow, but what a surprise I had when I realized it's indeed so sweet and beautiful. I'm in love! ❤️❤️❤️

BTW, I also thought we were using Ress to "corrupt" our friends and turn them gay. In the end it turned out Resnick was the only virgin among them (still have to check on Ludwig and Sam though) 🤣🤣🤣

I'm suspecting Sloth is not the last of them we will see around, and have an idea who will be the "vessels" for the others (Except Garreth, he always looks so calm, collected and wise (and hot! 🥵🥵🥵) I can't figure out what "flaw" could he hide. And, I suspect the HQ already has some intel on what's going on around the Raid, Ress and the Red Eyes' movements. I suspect that letter might touch those subjects. My mind is racing, I want to know more! 😅

This is a masterpiece, I hope it gets all the transcendence it deserves!

P.S. I love Edwin ❤️❤️❤️

(+1)

Thank you so much for saying all of that! It always makes my day to know that the game has brought so much excitement to someone. <3 Love hearing all the thoughts and hopes as well, so thank you!

I'll keep working hard to make Demons Within as awesome as it can be! :D

(+1)

You're doing awesome as it is my man!

(+1)

How many months do they release an update?

(+3)

Hey hey! I try my best to keep a schedule of releasing a new update roughly every 2 months! Faster if I can manage, but it's hard to do so! :)

(+1)

Yeah I saw just the amount of coding for Lykaois and it's insane. Not to mention the sprites, background arts, animations and story you have to write. Take a shit ton of time. 

(+1)

I understand, I have no problem, because this NV, I loved it very much, it is really a work of art, so I will wait for the next update🥰

(+10)

I will never forgive you for that fakeout with the commander in the baths.

(+2)(-1)

HAHAHA! What a professional teaser!! 🤣

(+5)

This game has no right to be this good, holy shit.

The dialogue and the story itself is so well written, the character designs are so well done and the mechanics of the game are so unique and interesting, honestly I can’t wait for more!

(+4)

I had my doubts when I looked at this VN at first, I remember thinking that it would be just yet another hollow story with forgettable characters... hah hah.




...




 Boy I was so wrong that I could throw myself in a clift thanks to the shame I felt for thinking that.




This VN is so refreshing! and it has such an interesting concept in hands, I would have trouble imagining quite anything like it, and to make it work like you managed to do is admirable.




I liked that it's written in an interesting and actually emotional way, and how detailed it can get, the pace of the story feels natural and not at all overwhelming at least for me... (Not as some, Others, That just throw you into the big and heavy plot at once without taking the time to actually set, discribe and get us familiarized with the world's atmosphere.)




I like that I can feel and see growth's and the perks in each character,(This maybe be minimal in some, but it's still interesting), Their flaws and how they make you wonder, 




*"how they would act now?..."* (And I just love that feeling)




One thing I also liked very much is how you are making bad endings. I LOVE BAD BRANCHES ENDINGS SO MUCHHH, AHHH!, SPECIALLY THOSE THAT ACTUALLY HAVE STORY TO TELL AND HOW DIFFERENT THINGS COULD BECOME!!(I love them even more much more if they get implemented in video games), ever since I played the 7.5.2 update and got the bad ending completed, I could not help but wander, Would you eventually make other bad ending branches? I know I would love to see it more! 




Now, I will talk about some in-vn things, So if you are new,




SPOILERSSS!


...
























...




















...




- I love how you handled us, (The demon, Lust), in the story when facing against that piece of sloth, I was so expectant and stressed for Resnick the entire time! And, (Hyper huge analysis incoming...)



I find it interesting that you expanded and we discovered a new ability in our lust, because ever since the start of the VN is clear that, we are lust, we are that force that exists within mortals, that primal instinct incarnated, but after the face off, I understand it as how, something about our time with Resnick changed us, and made us realize that, we are not just pure lust after all, but actually we are both sides of the coin of what can be defined as "Pleasure", we start off and often are a little bit cruel, straightforward, Intense, Entirely Playfull, how primal lust is typically associated, we are within the soul of Resnick, we just want to eat, we want to grow powerful and we use and manipulate Resnick's hidden desires to do just that throught the story, But, Somehow we start to grow, growing in a way that we actually start to see Renick as our only way to survive, this takes me back when we first infused Resnick with all of the power we managed to hold back from previous encounters, how we clearly are a little confused, curious and... even a bit worried about how Resnick will turn out. And how we are starting to see and maybe even understand deeper our true nature, after all we forgot who we were and our memories have yet to completely return, dispite that we go against our demonic nature to actually help. This is the start of our change, how we start to pay even more attention to Resnick's life, we don't see him now as just a tool but as our deared vessel. We can see that when that other black wolf with red eyes tries to kill us, sensing the inminent danger we go inmidietly to infuse Resnick so that we can protect him. After this something very heartwarming happens at almost the end of the said face off against the piece of sloth, we are pinned against the wall, hopelessly defeated, we are not strong enough to face off against this challenge, unable to infuse it with our own lust, this battle seemed lost, but then we start to have this feeling, of warmth we raise our arms to reach for it, as we start to understand that this maybe be love, not that intense lust we are accostumed to see. Its more sweet and warm. We start to channel it with no other choice as we start to feel and see this light pink expression of our power, something that feels so good. And we feel happy? Perhabs thats Resnick's connection towards his friends reaching out to you?...

After all of this, we somehow manage to sorta, Absorb? Or maybe even copy a bit of sloth's power? I feel that eventually we will be able to copy of absorb other demonic power as well.

(I don't know how far I got from this, did I even got it right? Well I dont mind more debate for this!!)

I just could go on and on with so many details I loved and want to point out. But I guess I will stop... for now.


For me, Definetly, 1,000,100/10 This is such a masterpiece I just so happened to stumbble across.

(Also, sorry for maybe bad grammar, English is not my first lenguage!😿)

(+9)

The bad ending in 7.5.2 contains some of the best written smut I have read in a long time 😳 it's super kinky and I loved every second~ amazing job

(+14)

This update taught me that Resnick has a very cute butt, and I can't wait for Edwin to learn this

(+1)

Is there a game guide or something? I wanna be able to navigate between the good endings and bad endings with multiple saves and such to experience the whole story

(+1)

I am doing that just just by trial and error 😅

(1 edit)

The android version is not updated? 

Can someone explain me the old version I have, when I update it it's still the old version when I play my load game 

The android version should be updated as well! This latest update is special and doesn't continue the story, but rather implements new stuff way back in the story. If you do get to the end of the story again in the new version, the credits screen that show up are different and mention that, though! Is it perhaps just that?

Mine is still the old version I want to play the 7.5 :<

Hmm, strange! I don't know too much about Android but the Android version has had a few hundred downloads and no other reports of this problem. Maybe try deleting the app and redownloading and reinstalling it altogether? Or testing it in a different device, if possible?

Okay I'll do it

see 

(1 edit) (+1)

Is it normal that the wolf's figure became almost transparent when the bull started playing with him? (In the bad ending, after we lost and used lust) It was so dim that I didn't even realize he was there right away! 

P.S.: I was waiting for the update, it turned out amazing!

(+1)

Hmmm! No, that's not normal! That sometimes happens because of skipping, if you were skipping the text up until a specific part and stopped before it fully appeared, I've noticed that can happen. Maybe it was something like that? I have it on my list to try to fix those things happening during skipping but it's a complicated matter so I haven't gotten to it yet!

(+4)

Good update(nose bleeding from the hot stuff)

(+7)

This new update gives so many CG! Damn! They are all hot!
I was expecting short Ending with 1 or 2 CG, but no! the story keeps going and going with 4 in total, and they are very kinky as well, lovely~

I hope in the future we can get more endings like this just plain lust~
+ Disconnected from "Main story/plot" but still serves to get know Gunther character as well.
Please make him appear in the future~ he is daddy material who like rough play, lovely guy

Will the game be translated into other languages?

(+2)

Thank you for porting the game to Linux 

(+1)

I'll try to make a FAQ somewhere as this is the question I get asked the most, and I understand why!

I do intend on making the game available in other languages, as many as I can! However, we're still early in the game's development and right now I'm focusing all my efforts on developing the story and the game as a whole. I feel like adding translation now would be hard and slow down all the other processes. When the game is further down its line, I will look into making it available in as many languages as possible, especially the most requested ones, which are Spanish and Chinese.

(1 edit) (+6)

I'm probably in the minority that doesn't care too much for the smut in these VNs so it's pleasant surprise reading one about a nascent sex demon that offers much more. The characters well-realized through both the expressive, clean art and the detailed characterization. I found their interactions very endearing. Many of them got a good chuckle out of me too. The writing also doesn't linger too much one character or scene when it doesn't need to and this is very much appreciated.

One thing I don't see often in other VNs is how detailed the action scenes are in this one. You did a great job weaving together techniques and tactics while escalating the action. I'm looking forward to seeing what you can do with them as the influence wheel fills out.

(+1)

Hey. This vn is truly something! it stands out with its shape, and I like it. I was wondering about one topic, tho. Will "We" (demon) be able to talk with our wolf? I was thinking about that since I started to play.

(-1)

That would make essence manipulation for Ress pointless, aside from overinfusing him, so that's unlikely. He may eventually remember what happened when he was overinfused tho. Or just feel our presence.

(+3)

I never really give answers to future questions because a lot is subject to change and it's best to experience things in-game anyway, IMO! I really appreciate your kind words, though, and I'm very happy to hear that people are enjoying the story and game so far! :D

Thx for a reply! Yeah, I understand what you're talking about and agreeing with you. I'll look forward for new updates and stuff!

(2 edits) (+3)

Usually VN text rich style is not my favorite, but this one hits different. The text appears bit a bit so I do not feel tired when read it. What a pleasant experience.

This remind me with Lust Desire, it is text rich VN but they write the story in a very tight style at small space. So the text size become small, hard to read and make my eyes feel tired so quickly.

Next paragraph bellow contain SPOILER !!!





I kinda curious with sexuality of every character, so here are my understanding about them :

Resnick and Edward basically are straight, but due to Lust's influence they are open to try new things.

Boris is straight but muzzle is a muzzle and hole is a hole.

Captain is Bi.

Bull mercenary is gay as af and I love him, hope to see more him in future.

Sam and Ludwig are not confirmed yet in VN.

(+2)

Started reading this gem about a week ago and finished it today. I'm obsessed with this VN! The demon mechanic of the story is amazing, and the squad of characters are all great. I can't wait to see all 6 parts of that deadly sins wheel glowing ☀️

Can't wait til the next update 👌
