Tags
Hidden Badge is a adult sandbox game developed by Night-Day-Night-Nine, built with the Unity engine. It was first released in May 2026 and last updated in July 2026. The game runs on Windows and is available in English.
Overview
The protagonist Ryoji, once an Agent of the Public Security Bureau (PSB), was forced to resign after being falsely accused following the mysterious death of his partner during an investigation of the gang “Scorpion.” Determined to uncover the truth, he dives back into the criminal underworld as a False Badge.
Joining him is his fellow PSB classmate Rinn, a cool-headed and disciplined Agent. In a web tangled with power, betrayal, and desire, she becomes the only one Ryoji can truly rely on.
As their investigation deepens, they uncover not only evidence of crime but a massive network of corruption tying the PSB’s upper ranks with political and economic forces. Meanwhile, Rinn’s younger sister Yaoyin becomes entangled, exhibiting increasingly strange behavior—her presence even surfacing on illegal platforms. Though she denies everything, Ryoji knows her freedom is slipping away.
Adding to the tension, Ryoji’s old friend Kaiza plays a shadowy role. While offering help on the surface, he increasingly meddles in Rinn and Yaoyin’s lives, making it harder for Ryoji to tell friend from foe.
In this convoluted struggle, Ryoji has only one option: move forward. Even if it costs him everything, the truth must be unearthed, and corruption exposed.

Developer Notes
Gameplay Features
This title introduces a streamlined turn-based combat system, designed for smooth progression without the need for repetitive grinding. A range of combinable and chainable skills adds strategic variety to battles without bloating playtime.
The game will include roughly 50 H-scene CGs. In addition to the popular chatroom system from the previous entry, we’re adding a Battle Assistance Mechanic—Kaiza may intervene during key fights, offering “help” that’s not always welcome. His interference could cause irreversible effects on certain characters—especially the heroines.
We’re also enhancing the pure love routes within the multi-ending framework. Their H-scenes will receive deeper narrative focus to satisfy players seeking emotional connection.
We aim to release the first playable demo by late September, covering the beginning of the main story and showcasing combat features.
Thank you for your patience and support. I’ll keep working hard to meet your expectations.
Changelog
v260629
This update adds two more days of the main story and officially begins Takiyo's romance route.
I originally planned to finish the Love Route in this update as well, but while testing I found several branching issues. Because of that, the next update will focus on fixing bugs related to the Love Route instead of advancing the story timeline. If everything goes as planned, it will also include a new Love Route CG.
I'm also not very satisfied with the current combat system. Right now, battles mostly consist of both sides trading hits until someone wins, which isn't very engaging. The next update will address the known combat issues and improve the overall battle flow.
One more small addition: Love Route CGs will not appear in the chatroom. (I don't think the protagonist is the type of guy who would upload photos with his girlfriend to an adult forum.) Because of this, I'll be adding a Gallery feature so you can review unlocked CGs without relying on the chatroom.
Known Issues
Chatroom videos may occasionally become unclickable. Opening and closing the pause menu usually fixes the issue.
Mouse movement on the map still feels a bit awkward.
Saving may occasionally fail. Please check whether the save slot has actually updated.
Some combat features required to distinguish the Love Route are still missing, so the Love Route remains temporarily locked.
The animation didn't make it in this time. It'll be added in a future update.
