Content

An unofficial patch for KoiKoi Love Blossoms (恋来い温泉物語, KoiKoiMonogatari) by Apricot Heart. It fully unlocks and uncensors the game and includes other useful mods.

HF Patch does not contain the game, only mods. You have to buy the game separately. You can buy the game on Steam or on DLsite. Both of these versions are pretty much identical and this patch will work no matter which version you buy.

This game is available in both VR and non-VR (desktop) versions. By purchasing the game you will get both versions. Non-VR version is available as free DLC on Steam, and as a separate download on DLsite.

Read the full HF Patch manual to learn more about what it is, what it does, how to use it, and how to solve common issues.

The base game (KoiKoi), and by extension this patch are not suitable for minors. If you are under 18 years old you can not use this patch. The base game and this patch contain only characters of age 18 or higher. The creator of this patch is not responsible for creations of its users and prohibits any unlawful use of this software.

Downloads

This download contains the entire HF Patch and can be used offline. You can use qBittorrent or a similar torrent client to open the magnet link. Old patch versions are available in direct download links.

Full patch (Everything is included)

Direct download links

Read before installing / Common issues

Download all parts to the same directory. The file names need to stay the same. You can use any directory other than the game directory.

Move the game to a simple path like D:\Games\KKLB if there are any Japanese characters in its folder path. If you don't, mods and/or the game might break.

If you have problems with installing the patch, check the solutions to common issues and the rest of the readme.

If the game is in Japanese, make sure you have the latest version and go to Settings (button with a cog icon in main menu) and select English in the dropdown setting at the bottom of the list.

The included uncensor is very basic: It removes the heart censors, replaces female body texture with a custom one, and changes the meat stick color to match the rest of the male body. It doesn't modify character models and the vag texture is very basic (it can be edited by hand, it's inside the BepInEx\plugins folder).

HF Patch does not contain the full game, paid expansions or any other pirated content. You have to buy the game and expansions separately.

This patch works with both Steam and DLsite versions of the game (they are basically identical). It works on both VR and non-VR versions.

To run the game without VR on Steam, you have to install the NonVR DLC from your Steam library. Afterwards you have to browse local game files and look for the "NonVR" folder and run KoiKoiMonogatari.exe (NOT KoiKoiMonogatariVR.exe). Warning: Even if you want to only play in the NonVR mode, you still have to install the patch directly inside "KoiKoiMonogatariVR" and not in the "NonVR" folder.

On Steam, you can run the game .exe directly if you don't want to be seen playing it on Steam.

None of the included mods modify game files. You can completely disable all mods by removing the winhttp.dll file and\or the BepInEx folder from the game directory.

If you want to make your own mods, check BepInEx docs and KKLB_SimpleUncensor source code.

There is no warranty on this patch or on any of the included mods. You are installing this patch at your own risk.

If you want to run the game under Wine/Proton (Linux, SteamOS, macOS, etc.), read this and this.*

You can see the source code here and information about included plugins here.

Thank you so much! I loved this game!

Meh

Damn. Would probably be all over it if it didn't require VR

ManlyMarco

It doesn't require VR, the steam version comes with non-vr DLC, same on DLsite.

2026-09-05 04:00 Yo Marco, nice work as always. Got a little problem though: When I apply the HF patch the game won´t open and I get the following message: "Failed to load PlayerSettings (internal index #0). Most likely data file is corrupted, or built with mismatching" I use the DLSite-Non VR version. Any ideas?

Try to re-extract UnityPlayer.dll from the game installation files into your install. If that doesn't help, also try MonoBleedingEdge, and then the exe files. Let me know how it goes.

ManlyMarco

Which files exactly did you have to replace to fix it?

Meh

Well shit. didn't even think to look for it XD. Thanks gotta check it out.

Bushy-Doe

Thank you once again. I’m still a super noob, sorry. I have 3 dumb questions: 1. What is the difference between KK Sunshine and normal KK? 2. I have KK After School (I assume this is After Party). It has dates you can go on… but I never see dating scene locations (like subway or otherwise). Just dialogue and static backgrounf how it’s “fun” and the day proceeds to Monday without H scene. Is this normal? 3. What other DLC is there aside from Sunshine, not on Steam?

ManlyMarco

1 Sunshine is a sequel with different content and mechanics. 2 DLC dates only appear after the first date. 3 Steam only has AfterParty which is all DLCs combined except for Darkness, which doesn't work in the Steam version of the game. Sunshine is not a DLC.

Thank you for your work. I wonder if it is possible to load a map (for example take a peek minigame) and stay on it. I'd hope for a freeplay mode to relax in the hot spring in the base game. Thanks again.

ManlyMarco

Not easily, you can open runtime editor (Pause key) and just move the player object to any point you want, you have to be on the correct map though. I'll keep it in mind next time I play around with this game.

Till Handsome

Thanks I found that ovras works just fine. The model weren't meant to be seen that close in that minigame. The search for the ultimate vr onsen experience continues. :)

sadly after i load the patch with current steam version 1.31, major defects on the shoulder area

ManlyMarco

Make sure the game is set to max quality not performance

SkyTerWar

The patch isn't working. I installed everything, but there's no content. What should I do?

Ency

the patch seemed to install ok for me, but with in game quality slider set to 3, the characters have pointy shoulders and other distortions on their models. This means i have to play on 2 instead, which isn't so bad. but is there a way of fixing it? Would also be great if there was a way of editing other skin textures, hair colour, stuff like that etc in the game other than just the 'KKLB_SimpleUncensor_Texture.png'?

Ency

Mine is set to max quality (level 3 on the in game slider) and that's when the distortions are there. I hadn't changed any f1 / f12 settings by this point. I downloaded v1.3 from your mediafire link after subbing here. any other ways to fix?

ManlyMarco

Level 3 is max performance, not quality

ManlyMarco

Level 3 is max performance, not quality. Set it to 1.
