About Luminary Protocol
You are transported to Lumis, a magic-filled copy of Earth torn from your reality and now ruled by gods and demons. The world is unstable, regularly absorbing chunks of other realities in violent convergences that reshape the landscape and introduce new creatures and peoples. What begins with familiar isekai setup quickly becomes a desperate fight for survival, complete with graphic violence, adult content, and mature themes. DESIRIUM shares the school setting and mix of monster girls and supernatural romance, though Luminary Protocol trades that game's lighter tone for a darker fantasy narrative where your choices shift perspective and occasionally change outcomes outright.
Luminary Protocol is an adult visual novel with RPG and dating elements. Gameplay focuses on exploration and character interaction rather than combat systems. Sex is part of the narrative here, built into realistic circumstances rather than handed out freely; the game contains one detailed sex scene in the current build alongside substantial nudity. An alignment system tracking Order, Chaos, or Balance adds another layer to how events unfold. Updates add roughly an hour of new story every few weeks, with each chapter centred on a faction's adventure and quieter scenes spent with specific characters.
Version 1.022R is available now on Windows, macOS, Linux, and Android in English. This is a solo developer's first project, built with Ren'Py and relying on AI asset creation to pair the writing with visuals. It suits players who want a dark, character-driven fantasy narrative with adult content and meaningful choices, rather than a straightforward power fantasy.
Developer's description
Luminary Protocol is an adult Isekai visual novel with a dark, unfolding narrative. You, along with others, are torn from your reality and thrown into Lumis—a dangerous, magic-filled copy of Earth ruled by enigmatic gods and demons.
The story begins with familiar genre tropes but quickly descends into a desperate, life-or-death struggle. Expect a mature story featuring graphic violence, sex, nudity, adult themes, and substance use.
The game is being completely rebuilt following changes in UK law. The first public release of the rebuild is v1.012. It contains one detailed sex scene and a lot of nudity. This is not intended to be a game where the MC does nothing and has people just throw themselves at him. Sex in this game is earned and intended to play out under realistic circumstances. This is a novel with a lot of sex, not a porn dispenser with a bit of story.
This is my first game, I have no development experience at all. I picked up renpy back In January 2025 and this is the result of much trial and error.
Explore a Shifting World
The world of Lumis is unstable. Chunks of other worlds are regularly transported there, merging with the landscape. This phenomenon, known as a ‘Convergence,’ brings new creatures, peoples, and technologies, offering unique locations to explore beyond the core world.
Your Path Through the Story
The game follows a linear main story, but your choices matter.
Flavour Choices: Most decisions will change your immediate experience and perspective on events, rather than branching the main plot.
Key Events: Rare, pivotal choices will have a significant and lasting impact on the story’s outcome.
Alignment System: Your actions will align you with Order, Chaos, or Balance. This will have some impact on how events play out and how characters respond to you.
A Note on Development & AI
This project would not exist without the use of AI tools for asset creation, as I don’t have the budget to hire artists. This allows me, as an amateur solo developer with no experience making software, to pair my writing with the visuals needed to bring the world of Lumis to life.
The Road Ahead: Now that the game has been out for 6 months, my goal is to continue to release a new chapter/update every 1-2 months. So far it has typically been 4-5 weeks per update. Each update has added about an hour of content. I intend to release updates as at least one fully complete “adventure” for one of the factions in the game, similar in size to what happens in Chapter 2. Alongside that, there are smaller scenes, where you get to spend down time with specific characters.
A note on Audio:
DO NOT USE THE ‘MUTE’FUNCTION IN SOUND SETTINGS. If you don’t want sound then lower the volume, but if you use the mute function it will block animations that have native sound from playing at all.
Version History
v1.022R Latest
v1.022R
Added in Cartographers Guild mission 1.
Added in Zara debrief 1.
Updated the notebook system to better handle messages from multiple people + added in message from Matsuyo to link the mission and the debrief.
Corrected a lot of spelling and grammar errors.
Fixed a bug that would cause a crash when choosing to take Marcus's warning about training seriously.
Updated every 2d image and sprite in the game + galleries and side images + some animations to reduce brightness and increase contrast slightly. AI 2d image generators tend to create quite bright, slightly washed out images and I decided it best to go in and add renpy controls to improve the colours etc.
Replaced a large number of sprites for the MC, Sarah, Alice and Lilly from the first part of the game. I have finally found out why they were being so inconsistent and have tried to fix all the worst offenders. Also replaced a number of animations so that they match the new sprites.
Added 2 x animations of Lilly for her dressing gown scene in the Prologue.
Fixed a mutant hand in the academy locker room image.
Fixed a mutant foot in Isabella's sex missionary POV scene.
Added in a missing animation towards the end of Isabella's sex scene.
Added in code that should catch if you are loading a save from the old version of the game, explain that you can't do that and then kick you back to the new game start.
A few other miscellaneous fixes (missing side images mostly).
Fixed an issue with Saga & Felsia's galleries not displaying, added an extra sprite of Felsia to make her gallery and profile screen less bare.
Added code to detect if audio is muted in the game settings and remove the mute on load. I have removed the option to add mute in the menu. This is because the mute function blocks animations that have their own sound from playing at all. I removed the option to mute in the last update, but didnt realise that the mute would still be stuck on for those who had previously set it. There would then be no way to unmute it. So the new code detects if mute was set on load and removes it. If you want the audio off, just lower the volume slider to 0.
Not including replacement sprites and animations, this update adds:
2 x animations of Lilly.
1 x animation of Isabella.
95 images/sprites of Emelia
36 x animations of Emelia
12 x images of the MC.
8 x animations of the MC.
18 images of Bram + speluncid opponents & villagers.
6 x animations of speluncid opponents & villagers.
10 x images of Saga
2 x animations of Saga
1 x image of Felsia
1 x animation of Felsia
27 x images of Zara
7 x animations of Zara
48 x backgrounds
2 x transition animations
**He also appears in a fair few of Emelia's images and animations.*
