About Zombie Diary: Survival with Sisters Miu & Rei
Zombie Diary: Survival with Sisters Miu & Rei is an adult survival game made by NightCapybara in Godot, using animated computer-generated artwork. After civilization collapses and the undead roam, you play as the sibling protecting Miu and Rei in a secluded forest house. The story has a dystopian setting and a survival goal.
The current build is version 1.07, released October 3, 2026, and development remains ongoing. It runs on Windows, Linux, and Android, with Japanese and English text, and is uncensored. The latest update adds a City location, diabetes medicine, Aoi storyline content, Aoi moving into the house, new Aoi Room and Basement areas, expanded pregnancy features including childbirth choices, and daily activity or resource gathering for late-stage pregnancy with reduced efficiency. A Linux version is now available.
Developer's description
Civilization has collapsed. The dead walk the earth. The only safe place left is a secluded house deep in the forest — and you are the only one standing between your sisters and the end of the world. Your mission: Keep Miu and Rei alive. At any cost.

FIXES
* Fixed the double-click issue when selecting gifts. Double-clicking will no longer accidentally give the item next to the one you selected.
* Increased max_stack to 9999 for all items.
* Fixed an issue where Mira / Daigo / Saeko could disappear after canceling the gift selection (pressing Back without selecting an item).
* Characters now correctly reappear and remain clickable after canceling a gift.
* The gift flow now resets correctly after cancellation, similar to Trader / Nurse.
* Fixed missing kissing sounds in the Miu and Rei scenes (lips and left breast).
NEW ENEMIES
* Added a new type of zombie. It is significantly stronger than regular zombies and starts appearing after Day 15.
* Added wolves as a new enemy type. They can randomly appear while traveling between locations.
PHOTO SESSIONS
* Added photo sessions with Miu, Reika, Saeko, and Yuriko.
* Added special pregnancy photo sessions for Miu and Rei.
* Added a new protagonist skill that increases the number of shots available during photo sessions.
* Added a new personal skill for the protagonist — SPY CAMERA.
* SPY CAMERA allows you to secretly take photos of the heroines while they are showering.
* Be careful: if you get caught, your relationship with that character will significantly decrease.
* All photos taken using SPY CAMERA are saved in a separate photo album.
PREGNANCY SYSTEM
* Added a pregnancy system. If you are not careful, your companions may become pregnant.
* IMPORTANT: Continuing from an old save may cause errors. Starting a new game is recommended for Version 1.06.
* Miu and Rei now have a new parameter — pregnancy chance. At the beginning of the game, the chance is minimal for both characters.
* Yuriko sells medicine in the village that can increase the chance of pregnancy, as well as medicine that can artificially terminate a pregnancy.
* If a companion becomes pregnant, she will temporarily stop participating in combat and resource gathering and will spend most of her time in her room.
* Pregnancy is divided into 3 stages. The first and second stages each last 3 days.
* Childbirth has not been implemented yet. To be honest, I still haven't decided on the best way to conclude this part of the mechanic. One thing is certain — there will be no children in the game For now, pregnancy will remain at its final stage until it is artificially terminated.
NEW CONTENT
* Added a new intimate pose with Yuriko.
* Added new intimate scenes with Yuriko.

I started testing the game and really liked it; it has huge potential to become one of my favorites. I hope the project continues and improves—here’s some encouragement, especially regarding the interactions with the sisters and the pregnancy aspect. Those…

A strange case where the game contains many fun mechanics, but with horrendously buggy vibe-coded implementation and zero balancing. But the sheer amount of things to do and the pretty character designs somehow push it to a net positive for…

Honestly, not bad. Needs work but it could go far. Combat need san overhaul for sure, some of the mechanics for the sex scenes needs work. All the makings are there, it just didnt work right for me as far…
