v5.1
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 separate 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.
v5.0
New features and notes:
Chapter 5 story continues around the end of September in-game.
Every girl gets at least 15 new scenes.
I updated the art style when going from chapter 4 into chapter 5. As such, some of the earlier art may look different from the new stuff.
When asked to invite Saya or Manami to your bedroom, choosing to not invite either will give you access to new content - 'The Virgin Route' as we started calling it. This route introduces some new FMG, as well as giving you access to the rest of the girls without first dating Saya/ Manami / Yuka. (The virgin route locks you out of meeting with them though!)
The gift system has been overhauled. With 7 vendors, and 70+ items. Going shopping does not skip time in game.
Added Side Stories to the chapter select screen - To unlock Megumi and Lisa side stories you must play the Queen Route. To unlock Ayane you must play the Kasumi route. To unlock Mika you must level up Kasumi to 8.
Added a 'music room' Jukebox to the main menu. As you hear songs in-game they will be added here for you to listen.
Added a cheat panel that you can unlock by completing the new story content. This panel allows you to get unlimited cash, stats, and swap girlfriends on a whim.
Do note that swapping girlfriends may break stuff especially around the early game (It is a cheat after all) But swapping girl before going on a chapter 5 date should be safe. Every girl has unique dialogue during dates if you are dating them.
Improved UI elements - you now have a collapsible hot bar on the right side of the screen.
Here you can access settings, save, load, inventory screen, cheat screen etc.
'Return' and 'Hide' buttons are on the bottom left corner.
The game is almost 5gb - and is the result of more than a thousand hours of labor and love. Please enjoy.
v4.0
N/A
Features completed routes for:
* Kasumi,
* Miyu,
* Kaori,
* Hino,
* Yuka,
* as well as story scenes.
Please report any bugs you find relating to these.
Missing content:
* Manami,
* Saya,
* Haruka,
* Naomi,
Do not report bugs relating to these as the content isn't there.
If you are dating Saya or Manami when entering ep4, this beta will automatically UNGIRLFRIEND you. Be warned. I did this because Saya and Manami's sections are not complete. So don't report it as a bug, you simply cannot be with manami and saya in this beta (from september 17th ingame)
**NOTE: if you use an existing save, you will get a grey screen error when you load. Just click ignore and it will never appear again.** This happens because the save is trying to load the music file as a WAV. But all music files are .OGG now to compress for filesize.

There's a decent amount of content in the game, and the chapter system makes it easy to access it all. The models are similar, but they're good, and the personalities all vary well. I also really like the premise with…

Not a massive fan of AiCG games. However in this game I can look past that, considering the niche of FMG (Female Muscle Growth) games. The art is serviceable enough, even if it has a little bit of Ai wonk…
