"What does the DLCs add?"

After School DLC:

  • 4 new voiced personalities: "Returnee", "Slangy/dialect girl", "Sadistic", "Emotionless".
  • MFF threesome
  • Expands dating system (4 new locations, new dialogue and new places for H scenes)
  • New outfits
  • Hair
  • Character cards

Summer personality pack:

  • 3 new voiced personalities: glossy/charming, honest/sincere, determined/willful.
  • 3 Swimsuits
  • Charactercard/s

Be aware, though, that the DLCs (personalities, new dialogue in dates and new H scenes) are untranslated, so you have to live with machine translations.

Install the HF Patch to get english translations and more!
Buy the DLC
You can buy the DLCs legally here:
https://dlsoft.dmm.co.jp/detail/illusion_0024/
https://dlsoft.dmm.co.jp/detail/illusion_0026/

Google Chrome makes problems, so use Firefox or another browser.

You can use a credit card OR buy "dmm points" with Paypal - and with the points you can buy the DLCs.

If you are logged in and have the DLC in your cart and have to choose the payment method, you need to click the button below. So for example, you want to buy After School, open https://dlsoft.dmm.co.jp/detail/illusion_0026/ and click the orange button. On the next site, the upper button is for credit card, the button below for points.

You should see "DMM Point" at the top. You need to click the yellow button on the right. On the next site you should see a button with the Paypal logo. Click it.

You can choose how many points you want to buy. One point = 1 yen. So if you want the After School DLC you need 6315 points.
Download the DLC
After you bought the DLC, you should see this page:
.
.
.
.
Click on the DLC (not the big yellow button) to open this window:
Right click on the button and choose "save as". Best is to just make a new folder and save all the files in the folder.



After you downloaded all files it should look like this:

Install the DLC
----------------------------------------------------------------------
WARNING
If you bought both the Summer personality pack and the After School DLC:

1. First install the Summer personality pack.
2. THEN install the After School DLC.
----------------------------------------------------------------------

Now click the .exe and this window show up:


Just let it extract in the same Folder where the downloaded files are.
Click the left button to extract.

After that you should have a new folder with japanese letters:


Open this folder. Ignore the FileCopy.exe. Open the setup folder. Now select abdata and UserData and put both in your Koikatsu Party folder. Overwrite if asked. (you do not need the InitSetting.exe, CharaStudio and the other folders!)
Back to your DLC folder (where the FileCopy.exe is), open the second folder with the japanese letters. Again, copy and paste it into your game folder. Just overwrite.

Done!
Download and install HF Patch
Download HF Patch

You need this to get english translations.

To quote from the HF Patch page:
A patch for Koikatu! and Koikatsu Party with all free updates, fan-made English translations and essential mods.

So it's basically a mod pack with updates, fixes, plugins, mods, ... and a (machine) translation for the DLCs.

Where to get it: https://github.com/ManlyMarco/KK-HF_Patch

Download and save it wherever you want. Should be one .exe and three .bin files.

Install HF Patch


Click the .exe and select the correct game path. (where the Koikatsu Party.exe is located)

Let it remove the problematic files ( interfering dlc files) if asked.

Either choose which mods you want or just use the default options and go on.
Test if installed correctly
Start the game. If it's not japanese: Good!

To test if After School is installed and working: Go to Extras and choose "Have Sex". If you can choose "Group" sex, then you are fine and After School is installed.

Also you should see new tutorial windows pop up ingame.

Thank you so much i got it to work and download! ive followed your guide step by step but ive yet again ran into another problem with the after school dlc.. when i tried to run the patch to install it.. it says it is missing regardless of what i just installed and placed into the koikatsu folder. would you need a screenshot for this as well?

So you DID download all parts but have problems with the installation. Okay.

The installer asks you where the other installation file is. So make sure you downloaded 3 parts (one .exe and two .rar-archives). If you did download every part: Make sure they are in the same folder. Or just tell the installer where the asked .rar archive is located.

If you encounter a problem and something happens which is not in this guide: Make screenshots and share them so one can take a look.

I dont see where it says userdata i can see the other things as well but everytime i try to download the dlc it reaches the end then it asks me something in japanese. im assuming its just asking where i want it to be saved so i click on ok but the same icon that asks me for a location keeps popping up everytime i press ok
