Some character from Asian languages are missing in the game's font assets.
If you experience missing characters in your custom missions, you can download the font file from the internet and put it in the game's root directory (where the EXE is). The game uses the "Noto Serif" fonts, so it would be a good idea to use something like the "NotoSerifSC-Regular.otf" (for simplified Chinese) you can download

I made a few custom missions, which you can find here:

Several additional missions.

These missions are one step like the main ones, some don't show progress until all conditions are met, and some work at specific points.
There are currently 10 missions that complement the main missions of the game and 1 guide that briefly displays the mission conditions in the game (available near the microwave at home).
Below are the missions listed in the format: mission conditions, reward, mission locations and where the mission is available
1) Use a dildo while flashing and watched [45rp, all_stages] - any place on the map
2) Use a dildo while naked and watched [90rp, all_stages] - any place on the map
3) While flashing maintain ecstasy over 90% without cumming near someone continuously [40rp, all_stages] - any place on the map
4) While naked maintain ecstasy over 90% without cumming near someone continuously [90rp, all_stages] - any place on the map
5) While handcuff to the object near someone have a ograsm [150rp, all_stages] - any place on the map
6) While naked and blindfolded handcuff yourself in a public place [150rp, Convenience, Residence, Park, StationFront, FashionShop] - many different points on almost all maps
7) While blindfolded step into the light [30rp, all_stages] - any place on the map
8) While flashing urinating like a dog near someone [70rp, all_stages] - any place on the map
9) While naked and blindfolded crawl to the center of the road [100rp, Residence, Downtown] - any edge on the roads
10) Show off your naked cumming body while urinating and masturbate [120rp, all_stages]

Here are three story-based missions I made where somebody caught you flashing and is blackmailing you into following their instructions. They are interconnected and take place in the shopping mall with one mission per floor, split up as a sort of checkpoint system. As you go up the floors, the demands start getting more daring.

Make sure you own the whole office lady outfit, have all the adult toys and emotes unlocked, and own multiple dildos.

Mission 1 starts at the entrance to the shopping mall. Stand on the zone wearing anything and it will change your outfit and move you to the starting position.
Mission 2 starts at the second floor rear escalator, same deal as above.
Mission 3 starts at the third floor escalator, same deal as above.

There's a lot of cool things you can do with this mod which I wanted to try out, but I didn't want to inflate the mission length too much. Even splitting up the checkpoints, getting near the end of a mission and having to start over because you get caught kind of sucks (although I guess that adds to the risk factor). Was pretty fun putting them together, it's not too hard once you get the hang of it.

So, I'm not usually into lewd games or much of a gamer, but I am admittedly a tiny bit of an exhibitionist and a friend who is well aware of that recommended me this game and ... the person who made it really understood what makes the whole kink exciting. I played it for much longer than I am willing to admit.

I'm not much of a technical person and had a friend who works in IT help me out a lot (which was a bit of an embarrassing conversation), but I started getting the hang of it ... I think. A few of the scenarios people shared before are a little too over the top and don't really do it for me (maybe the one from the previous post from cactuar excluded, that one was really fun ...), but I am having fun making up more realistic fantasies that could work irl? Maybe it's not what everyone would be looking for but I was convinced to share them here either way.



Anyway, here they are:

First one was a little practice round for making missions. Just placing your panties in a spot and hoping for someone to pick them up.

Second one is a trip to the convenience store and back with a few house visits in between. Maybe the last step isn't the most realistic scenario, but ... it's safe to do in a game.

I put my save in there, too, In case someone wants to skip to having all things unlocked. Nearly everything completed.



Also I am not a fan of everyone looking at you grossed out when they catch you (with the exhibitionist skill toggle thing), is there a way to change that? It really kills the vibe if the person seeing you naked isn't happy about that.

I never posted here before so I hope I don't break any rules or anything. Thaaanks.

Second mission won't start for me
Edit: And the third mission won't start too

Ah nevermind, I checked the mission start conditions and futa is against the start conditions. You might wanna put something somewhere that says that.

I removed that condition from the first mission but forgot for the other two. I initially had it in there because I didn't know if the detection would work with office clothes but decided to just take it out. Updated the missions.

How do I add custom missions to the game? I download them, but what do I have to do next? Can someone give a full but concrete guide on how to do it? thx in advance

Manaka's Bathroom Streak.

This is set early in Manaka's career when she is still exploring the whole idea of stipping in public. It starts at the lamp near the toilets at the park. She starts playing it safe but things quickly go beyond her main plans.

I recommend already being on the max level before trying this. Its also buggy sometimes I will revisit this properly when the script version of the mod comes out.

You will need a dildo and a vibrator and the ability to strip your coat.

Easy: Do the instructions
Medium: Do the instructions but pee before you reach the toilets
Hard: While catching your breath do something exhausting instead

I made a new mission today that starts right outside your door.

Lost Bet: You lost a bet against your best friend and have to get him a drink from the vending machine while butt naked, but things don't really go as planned ...

The Seduction skill needs to be on for this.

 

[Doppio1234]

Seduction skill didn't work in residence and couldn't complete your custom mission.
(I'm not sure bug? specification? Effective in other Stages)
But that's a nice story.

I sometimes have an issue where guys get stuck somewhere and don't follow me after catching me so anyone after that won't follow you until you find the one who is stuck and send him back home (or reward him for his patience), but it worked fine when I tried it. Don't forget it only works on some guys not all of them, the ones with the black uniform and young face can't be seduced since I think they are supposed to be high schoolers. Doesn't work on other women either.

Sex needs to be on in the options and the Seduction skill needs to be on at the laptop. You know it's on when you get a red warning message after leaving your house and no longer run home crying after getting caught.

(Older posts, please use V5 instead. )
Manaka Greatest Adventure V4
- total to 49 missions.
- All missions mainly focus on naked.

Manaka's Bathroom Streak.

I really liked that one, especially when the coat was suddenly gone ... but I hope I never run across a vibrator that short circuits when it gets wet.

Manaka Greatest Adventure V4

I want to try yours but I get a lot of errors in the second window thing.

Did you install other custom missions? Try moving them somewhere else and only keep mine. Don't forget it requires Version: 1.0.8 and Manaka v1.1.1

Ah, yeah, that was the issue. I only copied the missions but not the bepinex folder. It loads now. Thanks.

Guess we will have a mod on drone missions soon?

Manaka Greatest Adventure V5
- Added more new missions, bringing the total to 76 missions.
- Some missions are very difficult. No need to take them too seriously — even the creator isn’t sure if they’re beatable.

These introduce microstutters into my game, every few seconds, consistently. I tried v4 and v5.
