About this game

Luminary Protocol by JubsGames is an adult isekai VN with a dark, unfolding narrative. You and others are torn from your reality and dropped into Lumis - a dangerous, magic-filled copy of Earth ruled by enigmatic gods and demons. The story starts with familiar genre tropes and quickly descends into a desperate, life-or-death struggle.

Built in Ren'Py with multiple endings, the game leans into mature content: graphic violence, sex, nudity, adult themes, substance use. Sex is earned in this game - the dev explicitly frames it as "a novel with a lot of sex, not a porn dispenser with a bit of story." Lumis is unstable: chunks of other worlds Converge into the landscape, merging with it.

Expect adventure, animated, big tits, dating sim beats, exhibitionism, fantasy, groping, handjob, horror, incest, masturbation, milf, mobile-game UX, monster girl, oral sex, POV, romance, RPG progression, school setting, stripping, titfuck, vaginal sex and virgin content threaded into an isekai where survival is the gameplay loop and intimacy is one of its rewards.

Changelog

v0.50
- v0.51 Heidi's first event. Emelia special event. Around 21,500 words of story. Around 2,500 lines of scripting. New feature - messaging system in notebook accessible from the main hub page after Emelia's new event. Only one set of messages in it currently. 70 sprites and static images of Heidi. 28 animations of Heidi, totalling about 15.5 minutes. 5 x sprites or images of Karina. 1 animation of Karina. 12 x sprites or images of the MC. 11 x sprites or images of Emelia. 5 x animated transitions. 15 x backgrounds. Corrected some continuity and spelling issues throughout the game. Edited the home hub background image so that the dagger on the table is the one Emelia gave the MC. Corrected some unforgivable sartorial mistakes with the MC's new suit, Vivian should be ashamed of herself. There are a few for his suit in this update that I didn't have time to edit out, but will get around to it... Updated the menu background showreels, replaced some animations, added some new ones and added in some featured in the game.
v0.49c
patch Fixed more issues with some of the other Academy Missions backgrounds breaking.
v0.49b
Fixed issues with some of the Academy Missions backgrounds breaking.
v0.49
Reworked Zara's sprites and animations from the prologue and Chapter 1. Reworked Heidi's sprites and animations from the prologue and Chapter 1. Reworked a couple of Alice's new sprites in the prologue, as the facial structure was slightly off. Reworked, added to and replaced animations from Emelia's sex scenes in the 2nd Cartographer's Guild mission and her second character event. There's still a few more to replace, but the sex scenes are now more dynamic and longer in action. Reworked all the animations to reduce filesize, knocking about 1gb off the file size since 0.47 came out, despite all the extra sprites and animations that have gone in with this update. Fixed some spelling issues in the 0.48 content. Fixed a mission loop bug with Matsuyo's event. Fixed some formatting and spelling issues with some of the codex and character screen entries.
v0.48
Added Lilly's 2nd event. Added Isabella's first event. Added a special event for Matsuyo. Added 4 new codex entries Added a trans/futa content toggle to the MC's character profile sheet as the codex entries contain the first content of this type. Adjusted the game start to include a question about whether trans/futa content should be enabled or disabled. Fixed the new, thicker bolded text outline not properly applying to speech. Adjusted the image quality of most of the game image assets. Adjusted the image quality of the intro movie assets. The adjustments have resulted in a reduction in filesize of around 300mb, despite all the new assets from this update going in. I have still to go through and do the same thing with all of the game animations to get the filesize down further. In terms of stats... it comes in at around 20,000 words. 17 x backgrounds 1 existing background reworked. 5 x sprites of Matsuyo. 2 x animations of Matsuyo 57 x sprites or images of Isabella 29 x animations of Isabella 12 x sprites or images of Alice 6 x animations of Lilly & Alice 28 x sprites or images of Lilly 17 x animations of Lilly (including one 4 minute long scene).
v0.47b
Fixed a bug that would cause Zara's first event to repeat, rather than to player her second event, preventing progress with the Zara plotline.
Installation
1. Extract and run.
Developer Notes
This is my first attempt at a game. I hope it lands well, it’s not intended as a “quick release” kind of game. There is adult stuff in the first release, but the focus is the characters and the story. So if you are hoping for a shit ton of sex, this isn’t going to be the game for you. It will feature a lot of adult content, including a lot of nudity, horror, violence, drug and substance abuse, people doing pretty horrible things to each other, along with supernatural and magical stuff that definitely comes with an 18 rating.

Future tags (already planned for future releases):

BLACKMAIL, CORRUPTION, FEMALE DOMINATION, FUTA/TRANS, HAREM, INTERRACIAL, LACTATION, MASTURBATION, PROSTITUTION, SEXUAL HARASSMENT, SLAVE, TEASING, BDSM

Future tags possible; still considering if they will fit here or could be added but haven’t planned where or how yet. There is a really good chance they may never appear at al (and even if they do, they may be not involve the MC)l:

CHEATING, MALE DOMINATION, GAY, HUMILIATION, LESBIAN, MULTIPLE PENETRATION, SEX TOYS, TENTACLES, TRANSFORMATION, SISSIFICATION, URINATION, VOYERUISM, ANAL SEX

I think I overcomplicated this when I first wrote the disclaimer about the controversial tags.

Short answers..

NTR .. this is not an NTR game, it is not intended to appeal to that audience. Not that I have a problem with that audience or that type of content, it's just not what this game is about. There are 2 characters who may get scenes where they have sex with other people. One of them is a prostitute, it happens before you are romantically engaged with them and you don't see it. The other is a key character, but it is entirely your choice as to whether it happens or not - in other words it's avoidable.

Gay/sissification - not coming any time soon. If it does eventually make it in, it won't be main characters. It will be something happening to non-key characters during one of the plots and you won't see anything if you don't want to see it.

Futa/Trans - There is one god and one key character who are intended to be transgendered. They were not born male and then changed, it's their species or their divine nature. There is a possibility that a male character may go through transformation. I say possibility because I have the plot line in my head, but it's way way way down the list of priorities. If it does get added, then it will be avoidable. The content will be avoidable and if I can allocate the time to do it, I will try to make a normative and a trans version available for these characters.

Rape - the MC does not and never will engage in any kind of non-con, assault or rape. They will encounter other people who are, have or could be about to experience this. His role, is to stop it happening and/or punish those who did it.
