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.
This is my first game, I have no development experience at all. I picked up renpy back In January and this is the result of many trial and errors.
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. I consider the ‘Balance’ route to be the canon path through the narrative.
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: I’m releasing the game at this point because I have finished building the technical framework that the mission system uses and it has a pretty good amount of content for a first release. Now I can just get on with new content, rather than worrying about trying to work out building UI, menu and mechanics. My goal is to release a new chapter/update every 1-2 months (ideally 1, but I’ve seen too many games over-promise and under-deliver with timescales). 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, I hope to include some smaller scenes, where you get to spend down time or go on other adventures with specific characters. That’s the idea.. at this stage I’m still working out what is feasible as a part-time developer.

v1.022R
Spoiler
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.

Study: Watching Porn Boosts Support for Homosexual Marriage
The study, conducted by co-authors Paul Wright of Indiana University and Ashley Randall of the University of Arizona, proposes that exposure to pornography helps open the minds of straight males — particularly less-educated straight males — making them more likely to accept the idea of “non-traditional sexual situations,” the Washington Examiner reports.

The Homosexual Manifesto
“We shall sodomize your sons, emblems of your feeble masculinity, of your shallow dreams and
vulgar lies. We shall seduce them in your schools, in your dormitories, in your gymnasiums, in your
locker rooms, in your sports arenas, in your seminaries, in your youth groups, in your movie theater
bathrooms, in your army bunkhouses, in your truck stops, in your all male clubs, in your houses of
Congress, wherever men are with men together. Your sons shall become our minions and do our
bidding. They will be recast in our image. They will come to crave and adore us.”
