StrongGirls FMG Visual Novel

Sunday Devblog 06/01/2025

Happy Sunday!

I hope you enjoyed Episode Raven last week! This one was a little different. It ended up being the longest side story to date and packed in some significant lore for the StrongGirls universe. It was also a blast to write a true anti-hero character and really lean into her perspective.

With Raven wrapped up, I took a short trip, so this week hasn’t been a full work sprint. But I’ve already kicked off work on the Sumi side story.

This one will be a more classic FMG story, shorter and more contained. After Raven’s scope creep, I definitely need a breather. I’m also putting more time toward Chapter 6 of the main game.

So now I ask you: what are you hoping to see from Sumi?
I’ve got a first draft of her story written out, but I’d love to hear your thoughts while it’s still early. It’s always helpful to align expectations and make sure it delivers what you're excited for.

Hope to share more soon! Thank you as always for supporting StrongGirls!

Happy Friday!

This weeks album I played with two separate concepts. One is the girls checking themselves out. I am a huge fan of the pose where a muscular girl flashes her abs and tits.

I also went big on this idea of a barista girl growing, and offering milk for your coffee with breastmilk. Might be weird for some of you. I like it though! I know this would have been a perfect concept for Haruka but I don't want to suggest that lactating is a canon concept in the game. Maybe if you like it, it could be a serum variant. FMG breast milk.

Happy Sunday!

Work continues on Episode Raven. Even though I initially wanted to keep this one short, it’s definitely starting to grow bigger than planned (Ouf … but that's good news for you!).

I decided to bring Raven’s boyfriend, Kei, more into the plot. He’s got some key connections and ended up being a great way to connect the dots in the story.

I know I’m being vague here, but that’s just to preserve some surprises for when you get to play it. Right now I’m aiming for a release before Saturday. I’ll be doing some travel starting next weekend, so that gives me a firm deadline to work toward.

In other news
Last week I posted the poll for the next side story, and the winner is… Sumi, the art teacher! (or I think it will be, poll remains active for another week!)

I guess you were all a little too eager to see this melancholic teacher get a taste of the good life with the muscle serum. I’m really excited to write her story! I already set her up as someone who needs a good energy boost haha!

Since she’s a teacher, I’ll need to be thoughtful about how it fits into the bigger story. Speaking of teachers: Kaz ranked high too. Looks like you're all dead set on turning the whole school into muscle girls. I can’t blame you!

The Sumi side story will be coming in June, and I’ve got some amazing stuff planned for it.

Thank you as always for your support. I’m pumped to get Raven’s episode wrapped up and can’t wait to show you what’s next!

Today we're getting Nene and Raven!

I needed images of Raven doing some 'rough and tumble' play with her lover so here are some concept images from that. But I rewrote some parts of her side story so I won't go further with the concept. But makes for great images to share in the NSFW friday post!

Why is Nene here? Well for most girls, I managed to get them to look great in the more advanced model but Nene I struggled a bit. I think I've gotten to a point where I can do a sort of stocky short build with pecs without getting silly proportions. Let me know what you think!

June Side Story poll

Alright! The nominees are the same as last month. Take your pick! Multiple choice allowed.

Sunday Devblog 05/11/2025

Happy Sunday!

This week I’ve been working on the Raven side story. Formerly known as just the goth girl.

We already know from Chapter 5 that she eventually steals serum from the StrongGirls Club, and this story will dive into the events leading up to that moment.

After Nene’s little break-in at the lab, security at the club got a lot tighter. Now, dancers aren’t allowed to take serum off club grounds, and that’s really not sitting well with Raven. She used to enjoy the perks of serum off-duty, and now she’s stuck under stricter rules. Being treated like a kid, as she sees it.

To make things worse, the person policing her is none other than Nene, the very reason the rules changed in the first place. (Being treated like a kid, by someone who acts/looks like one!)

Raven is very much an antihero. Her motivations are entirely self-serving. She doesn’t want to play by anyone’s rules, and this story gives us a deeper look into her mindset and frustration.

It’s shaping up to be a fun and character-rich episode, with appearances from other StrongGirls Club locals, like Mika, and a good amount of tension and attitude.

I can’t give you a solid release date just yet, but I’m committed to having it ready before the end of May.

Also, I was supposed to post the poll for June’s side story already… whoops! It’ll be up soon, I promise. So vote carefully when it drops ;)

Thank you always for your continued support! looking forward to sharing more soon!

Doing some classic drink serum and grow images. How do you like the art? Been working through some improvements. It opens up more possibilities for poses, clothes, etc. Hope you like it! Last week user TheScorpion613 requested face sitting. I did an attempt! Hino with MC between her thighs. Would not have been possible without the model upgrades.

Let me hear your ideas for future albums!

Sunday Devblog 05/04/2025

Happy Sunday!

This week I’ve been deep in story planning for Chapter 6, so I don’t have much in terms of flashy screenshots to share just yet. Most of my time has gone into figuring out the core beats of the chapter—what scenes need to happen, how the story progresses, and how to keep everything tight and engaging.

That said, I want to take this opportunity to ask you—what would you like to see in Chapter 6 or beyond?

While I’m very careful to keep the scope under control so we can stay on track for a summer release, your feedback is always valuable. I want to make sure the experience meets your expectations, while still being realistic about what I can build in time.

A few things to keep in mind about Chapter 6:

• It will be very story-focused, with time skips to cover the winter months.

• I do not plan to add dozens of individual dates per girl—not like Chapter 5’s 12-per-girl scale (that was intense!).

• Instead, I’m aiming for around 3 new dates per girl, across 9 girls, for a total of 27 dates. That’s still a lot, but feels manageable while keeping focus on the main story and special events.

One date idea that keeps being suggested—and I totally agree—is a gym date! We definitely want to see our strong girls hit the weights and show off a bit in their element.

So let me know:
What kind of scenes do you want to see?
Any specific events or ideas you think would fit well in the winter arc or the evolving story?

Thanks so much for following along and supporting the project. I’m excited about where Chapter 6 is going, and I’ll keep you posted as things come together!

Release date?

Yes I realize I mentioned summer. I at least hope to meet that. But I will need to keep the scope in check to make that a reality. The way I imagine is:

• May - Raven side story

• June - Another side story (Poll to be posted this week!)

Then I won't do more side stories until chapter 6 is ready. Which I hope to be August, giving me July to do everything I can to make it a smooth launch.

This will be possible if I keep the scope of the side stories also within reason. I realize I've kept making them longer and longer with each one. But I cannot keep doing that sustainably. I hope to settle on making them similar length to Mika.

If anything, making side stories is a lot of fun and really allows me to focus only on narrative which is great. No gameplay or branching paths considerations. But ultimately we are here to play a game with player choice so side stories will never be a priority over the main game.

Anyway! Hope I didn't ramble too much. Let me know your thoughts. As always, thank you so much for your continued support. This game wouldn't exist without you!

Please write in the comments your wishes for chapter 6 and beyond🙏

Unused Chapter 4 images (REUPLOAD)

This post is for archive. Previously I shared links on discord and it was hard to find all the posts. So here is the complete chapter 4 unused archive.

Unused Special Serum images (1708 total images)

These are the images from the special serum scenes for every girl. Both Queen and Kasumi route. To see the whole album, like always download the ZIP and extract.

There should be a lot of unused nsfw images, and giga size images in there.

But it isn't all nsfw. Some test images are present like outfits. I included some pics from my tests using a new illustrious model.

NSFW Friday 05-02-2025

Today's theme is Mika and Hana going wild at the club! The idea was suggested in a previous NSFW Friday post. I couldn't find the original comment but I took note of it! That said, please comment below what you'd like to see!

Sunday Devblog 04/27/2025

Happy Sunday! Hope you're doing well.

First off, did you enjoy the new 5.1 update that dropped on Tuesday? I hope you had a great time with the new special serum scenes! If you missed it, it's here: https://www.patreon.com/posts/chapter-5-1-link-127210621

With 5.1 out of the way, I’m now shifting full focus onto the Chapter 6 update.

A few details about Chapter 6:
It will lean much more into the main story, with the timeline jumping forward between several significant events. On the Kasumi route, Yuka’s relationship with Kasumi will face new challenges and be tested more deeply. On the Queen route, Harumi will push for expanded testing on more subjects such as elderly people.

The villain of the story will also begin to make a move, especially as Yuka starts to get closer to uncovering the truth about her father.

I’m keeping things intentionally vague here to avoid spoilers, but I hope that gives you something to be excited about! Right now I’m working on the scripts for the update, so no screenshots this week, but once the writing is locked in, I'll have more to show.

On a personal note, I’m thrilled to finally have the special serum scenes and the promised teacher scenes finished. It feels great to have kept my word and delivered, and now I’m so excited to be moving back into story-focused content. This is the part of the project I’ve been looking forward to the most.

Switching gears for a moment: about the Goth side story, the girl has officially been voted to be named Raven. I’m aiming to deliver Raven’s side story sometime in May. My plan is to first build up strong momentum on Chapter 6, and then slot Raven’s story in when there’s a good window. Plus, after just releasing 5.1, it’s good to slow down a bit and make sure the next releases are as polished as possible.

Thank you so much for your support and excitement!

Chapter 5.1 released! [Download Link]

This release includes all content and side stories up until now! You do not need to download any other uploads, this is the latest.

The long awaited Special Serum scenes are here!

You will see 4 versions

• 4k PC

• 1080p PC

• 4K MAC

• 1080p MAC

Not sure which version to get? 1080 is a smaller file size - quicker to download. If you plan on playing on a big screen that supports 4k, go for the 4k version.

Note: Saves are not compatible between versions. If you played 4k before, but switch to 1080, you will need to start over.

The new stuff:

• Special serum scenes! 18 FMG scenes in total with 148 images. 2 scenes for each girl. To unlock you must not run away when the failed serum is used on you in either Queen or Kasumi lab route. Then they will give you the serum. You can use it once per playthrough.

  • This means if you side with Queen -> You get the Queen special serum, it can be used with your girlfriend once.

  • Same with the Kasumi lab -> You get the Kasumi lab special serum and can only be used once per playthrough.

    • HINT: If you want to experience all scenes but don't want to do 18 separatee playthroughs, you can keep a save on each of the two routes, then use the cheat menu to swap girlfriends before using the special serum.

    • The option to use the special serum appears in the evening on September 24th (assuming you didn't run away from the September 22nd serum test.)

    • 

• Random encounters at school. Can happen on any weekday. 30% chance. Encounters can result in small stat bonuses.

• Teacher scenes.

  • History teacher, Toma starts on Mondays in October

  • Naomi starts on Fridays. (6 new teacher scenes in total)

• Nene and Jiro side stories added to the bonus content section in chapter select

  • Jiro side story is unlocked on her third lesson in October.

  • Nene side story is unlocked by reaching the Kasumi level 9 scene (When you get 9 stars with Kasumi)

• New regular sprites for Miyu, Hino, Kasumi

• Cheat menu added to the main menu -> Requested by mobile users where the quick menu is bugged. (unlocks once you reach the end of chapter 5, stays unlocked acros saves)

• All currently known bugs addressed. If you encounter any bugs, please post it in the feedback forum on the discord or if you don't want to use discord, send me a private message.

In short, this update adds a lot of FMG content, and makes the school feel more significant.

Note: This update isn't a continuation of the story.

I will be working on chapter 6 from now so please stay tuned. I hope to get that out sooner since I will focus on a lot of story, and less on adding individual scenes for the girls. My scope for chapter 6 is very strict. I will share more in next Sunday update!

Sunday Devblog 04/20/2025

Happy Easter! 🐣💐 Hope you're having a wonderful day, whether you're spending it with family, relaxing, or getting some well-earned downtime.

Now for the update—unfortunately, I need to push the official release of the Special Serum Update to Tuesday.

The scenes are mostly complete. I still need to do some final revisions on Haruka’s scene, take care of bugfixing (my goal is to have all known bugs fixed in this release), and prepare the 1080p version of the build as well.

I missed my release mark mainly because of Easter—I didn’t expect to be this busy with family stuff. I still managed to crank out a ton of work over the weekend, just not quite as much as I wanted. On the plus side, I got to enjoy some quality time with my family… and 1.5 year old daughter learned to dance, so I’d call that a win!

Thank you all so much for your support and your patience—I really appreciate it. I hope the Special Serum scenes live up to expectations. I’ve pushed myself on this one, especially by making each girl’s encounter unique, with new outfits and new locations sprinkled in to keep things fresh and surprising.

The total new image count is almost 200, including the new backgrounds, and outfit sprites. The FMG sequence images for all the girls make up the bulk of the images, with the total being 148 images.

Can’t wait to share it with you soon—just a couple more days!

(P.S. This post is light on screenshots since Patreon is strict on me because these posts are public. I will post some in the Discord game updates channel.)

(Growing on dates vol2) NSFW Friday, 04-18-2025

This week I am continuing with the concept I started last week, doing the girls in different outfits and having a simple growth result. I tried to have a nsfw and a sfw version of every growth.

I went a bit wild with Hino's outfit so it was challenging to make it consistent between pics but I like the aesthetics of each of her pics so I decided to keep them in.

Happy Easter! I guess I should have done a Mika set to go with the spirit of easter bunny but too late now. I'll do Mika next week!

Always open for suggestions. I am working hard to get the special serum update ready. I got a bit left to go, appreciate your support on this! Can't wait to share, it's going to be great!

Sunday Devblog 04/13/2025

Happy Sunday! Hope you're doing well.

This week we did the poll for the name of the Goth Girl, who won the Side Story bid by a landslide.

All names were suggested by community members. And the winning name is Raven! I imagine it's a bit of a stage name. Perhaps she chose it when starting at StrongGirls.

I already started chatting with Beriya about storyboarding her side story.

This week I wrapped up more work on the special serum scenes and I am working hard to get these done soon.

Last week the Sunday post got removed for violating rules on patreon. It got restored when I removed all screenshots so hope you don't mind if I go light on screenshots this week. Besides, I am mostly working on NSFW scenes anyway so I don't want to spoil anything.

I am still aiming to release this update next week but I also want to do a thorough debug of the game to get rid of any remaining known bugs. Not sure how long that all will take.

As always appreciate your patience! Thank you so much for the support and I will work hard to get at least this out in April and hopefully the goth girl too!

Have a great week,

Jon

Name for Goth Girl Poll

Since she is on track for the next side story it's about dang time she got a name! It's multiple choice.

(Growing on dates vol1) NSFW Friday, 04-11-2025

I had the idea to do a sort of 'What if girls grew on dates?' scenarios.

I wanted to use the opportunity to make the girls from the game in new outfits. I had to tweak a ton to make them grow like I wanted with the outfits. I decided to do NSFW and SFW versions of the growth- For Saya the SFW version of the jumpsuit turned out better - the jumpsuit unzipped like I wanted. Makes me think there should be more girls in jumpsuits in the game!

I will do girls growing on dates vol2 next week! Kasumi, Naomi, Haruka, Hino, Miyu, let's see if I get through all of them!

Sunday Devblog 04/06/2025

(Note: Had to remove all screenshots to make sure this post passes patreon guidelines)

Happy Sunday! Hope you're doing well. I've been working full force on the Special Serum scenes since the release of Nene side story.

To make each of the special serum scenes more interesting I altered where they take place. So rather than just the girl coming to the player's room, making them all feel too similar the player often goes to the girl to surprise her. This was suggested by our members in the discord and I am so happy I took the suggestion.

It gives me a chance to really play with the scenes and make them feel more unique.

I've been hard at work making the lead up to the scenes something to enjoy as well.

I've also leveraged the new ChatGPT image generator model to improve the backgrounds by a ton. It helps me recreate familiar locations with less AI artifacts, making the picture seem more intentional. Here is Naomi's apartment recreated.

It really lets me be specific with what is in the scene. In this example, Naomi has discarded clothes, dumbbells, and a white lab coat hanging on the wall. I use the original image as the input and specify the changes. I also wanted to add a sink, microwave, and fridge because Naomi's old apartment image had only a mattress and pull up bar. Now it looks more like a place someone lives.

I similarly recreated Kaori's rooms, and steaming background. Adding discarded snack bags and sodas hehe.

ChatGPT is also great for changing the time of day! Ever wondered what the school would be like at night time?

I am working really hard to tie these special serum scenes together. I hope to get them done this month!

As for side story, the poll is up with 1 more week to vote! Goth Girl seems to be winning! Even though she doesn't have an official name yet. I guess she really made an impression in Nene's side story. I will take all the name suggestions from before and put them in a poll soon. We will have a community voted name for her.

That's it for this week! Very excited for the new backgrounds. It's never been easier and that's good news for all of us! It means shorter development time, and more expressive freedom in bringing the world to life.

Alright that's it for today, I'm going to get back to the grind!

NSFW Friday April

I decided to go for a sort of collage. The theme is all the 9 girls, from above.

Let me know if you have other themes in mind I can do for future NSFW Fridays!

Unused Nene side story content (1120 files)

So the absurd amount of unused files for Episode Nene is due to:

• These cover all the girls that appeared in this side story.

  • Goth girl fmg,

  • Hana,

  • Mika new sprites,

  • dancers,

  • Bouncer,

  •  as well as Nene

• Getting a giga sized Nene was hard.

I wanted her physique to be unique since she needs to be small, but big. But turns out that getting a small big girl is pretty much a contradiction. A lot of ultra sized Nene's in there. Tons of iterations.

Hope you find it insightful!

Sunday Devblog 03/30/2025

Happy Sunday! I hope you had a chance to play the Nene side story that released yesterday! In case you missed it,
Download link is on itch: https://stronggirls.itch.io/nene-fmg/patreon-access

With me working to meet the deadline for Nene there is not much else to share for this Sunday Devblog.

For Super supporters and above: I just posted the poll for the next side story!

 I just posted it and votes are already coming in.

Hope you have a good week ahead! I plan on making loads of progress on the next update for the game with the special serum. Hope to share more soon.

As always, thank you so much for the support!

Next Side Story poll!

I wanted to finish Nene's story before posting this! With so many options I will enable multiple choice.

Episode Nene Download link

It's here! March's side story featuring Nene! This side story is about as long as the Mrs. Jiro side story, the longest side story so far. I hope it will be a lot for you to enjoy! The story was written by Beriya who also took on Episode Megumi.

I did my best to keep some surprises. Can't wait to hear your thoughts once you've played it! Try to share in the story-spoilers discord channel and avoid posting spoilers openly.

Sunday Devblog 03/23/2025

Happy Sunday! Hope you're doing well.

This week I've been busy working on Nene’s side story.

It's so hard to show off without spoiling too much so I try to be selective with the screenshots.

It’s been a fun challenge since I’m adapting a script written by Beriya, who I commissioned to handle the writing. That means I’ve had to make new sprites and depict scenes I hadn’t planned for—like a full body shot of Nene on a stepladder.

Another fun one is a comparison shot of Nene next to some construction workers, really driving home how tiny she is.

A big focus of this story is showing just how small Nene feels in the world, which leads naturally into her moment of getting her hands on the serum. We also decided this would be a great time to introduce the Goth girl—the same girl Kasumi mentioned in Chapter 5 as having stolen serum.

Since the story involves the StrongGirls Club, we’re also bringing back the bouncer. I gave her a full redesign—ditched the tie and button-up shirt, and gave her a tougher “don’t mess with me” look in a black tank top.
I had 2 reasons for redesigning her.

• She was originally made with the old art model so she was due for an upgrade.

• Her old sprite is too big and was never made to be on the screen along with other characters.

I hope the redesign works for you!

All in all, this is a really fun story and I’m having a blast pulling it all together. As for release, I’d say closer to next weekend, since I’ll need a day or two for proofreading and feedback. Many key pieces are already complete like Nene's giga size, and other fmg scene.

Hope you’re excited for it!

Also, this week I’ll be posting the poll for next month’s side story— as well as more of the remaining unused ultra tier content from chapter 5. stay tuned!

Manami chapter 5 unused (545 files)

I hope to get the rest of the unused out soon!

NSFW Friday March (2025) week 3

Alright so this is a minor spoiler for Nene side story... The Goth girl will make an appearance. She plays an important role actually...!

But she doesn't have a name yet. Anybody willing to float your ideas?

Sunday Devblog 03/16/2025

Happy Sunday! Hope you're doing well.

This week, I’ve been working on Kasumi’s special serum scenes, and along the way, I decided to update her non-muscle sprites as well. Since the special serum scenes start with the girls in their normal forms, I wanted to make sure Kasumi’s base look felt consistent and up to the current art standard. Let me know what you think!

Here we have a comparison of the old, vs the new, vs the muscle.

While I don't want to show off the special serum art (plus I can't show nsfw stuff in public posts - patreon rules) - Here are shots from her special serum scenes before the chaos.

Mika is a bit sticky, doesn't get the hint. Gotta convince her to leave hah!

Updating Kasumi's non muscle sprite also felt appropriate since she will play a role in Nene's side story.

Release Schedule

Next up: Nene’s side story! As I've said before, the writing was outsourced so I will be getting the script on Monday. From there I will work on getting the art all made. Depending on how long the art takes, we might be looking at a release after next weekend. I've been experimenting a lot with hyper sizes to prepare for Nene and thank you to all the Super and Ultra supporters who voiced your thoughts on the last NSFW Friday post! It helped me make some decisions.

I got Nene's giga size done, and as much as I'd love to show it off, I'll keep it saved until the side story is out.

Giga size aside, we still haven't seen what Nene looks like without the serum. I will probably iterate more but this is a start:

I’ve been grinding hard to get all this content out as soon as possible while keeping the quality high. These updates take time, but I want every scene to feel polished, and worth the wait. I appreciate your patience and support—it really keeps me pushing forward!

Looking forward to sharing more soon. Have a fantastic Sunday!

- Jon

NSFW Friday March (2025) week 2

This week we are doing hyper sizes. I struggle to get these to look aesthetic- it's very easy to go full meatball territory. With Nene coming up I want a big body but not comically misshapen body. Let me know which ones here you like the most!

Saya is the model because I can imagine her overdosing just for kicks.
