Story Introduction:

There was once a powerful demon who could control the thoughts and actions of others and use them as it pleased.

For thousands of years, the demon roamed the earth, spreading fear and terror wherever it went. Its magic was so subtle and effective that once you were caught in its web, it was nearly impossible to escape.

Eventually, the people came together and sealed it away, ending its reign of terror once and for all.

This is the lie they told their children about you.

Any plan for "group corruption even" if both Rin/Eri , Hana/Ai or Kaede/Kiyo reach 1/2 at the same time ?

Will there be a point in the story where the characters give in willingly without lust corruption or powers ?

Hi dear unusual fish, how are you, I have a question and a doubt.

•The question is, will Gloria have a new update? Well, I’m very curious, but if you don’t want to say anything else, what will be the release date??

•Doubt and Abigail and MC will have a romantic bond or not?

*Sorry about my English, I really like your game but everyone praises it right?, Sorry for wasting your time★

(1 edit) (+2)

Its okay don't feel bad about asking no one is here to judge you (at least I don't think so) don't feel bad about asking question's unusualfish and others are here to help you understand more about the game so if you have more questions don't feel afraid to ask 😁

(2 edits) (+1)

Thank you for your beautiful words. Well, I’m a little embarrassed, but thank you!

(sorry now that I see😅)

(+1)

Gloria will receive her update once I'm done giving all the current girls their quest! I update character side quest in a cycle where all girls will receive one before I circle back. And of course you will get your time with Abi too! Once she arrive that is (-ω-ゞ

(-5)

hey UnusualFish, can you add this update where MC can masturbate when he's alone, or in a restroom? or, when he can masturbate in the school's bathroom

(+1)

Sorry, but lore wise, that would just be a waste of his energy

(+2)

Just signed up too say the 0.6.5 scared my ass off good job you crazy bastard

(+1)

Doing my job (-ω-ゞ

Hielo 13402 no sé si esto te sirva como pero seguramente se refiere que si más personas hacen contacto con dicha energía no solo traería demonios sino que existe la posibilidad de convertirlos en marioneta o incluso que pueda poseer a más de una persona aunque bueno es solo una cosa que se me ocurrió ya que he visto la historia 5 veces y a veces se me ocurren cosas que pueden suceder en la historia 

Estás en algo aquí, amigo  (′v‵ ) 

When is the next main story quests? I'm really hooked

v0.7.0, it will take a while (′v‵ ) 

(+1)

Hey senpai. 

I played the main story update. 

Is there going to be Four horsemen of the apocalypse?

Cause gramps say "This thing is like virus"

Maybe it can chain to the Pestilence?

(+1)

Nope, Four Horsemen are apocalyptic level entities and the sinners stand basically zero chance against a single one of them (′v‵ ) 

(+1)

Will there be a scene where, in the group of girls, we can turn invisible and touch the girls body and stuff and they won't notice it?

(+2)

There are those scene for the main girls individually, but a group version could be interesting

I really like this game.I want to ask when the task of Hanas will be updated. Like she very much.

(+1)

When all the girls have received content, I will cycle back to Hana. Her aunt's turn will be in v0.6.7 (′v‵ ) 

Ok, thank you. I am a player from China and I like your game very much.♥(。→v←。)♥

(1 edit)

Where do i find Mio's 2nd Corruption event?

And even Better would be to know where and when i have to be for like Ai's and Hanas corruption event.

Hi there, Mio, Ai, and Hana's corruption event are all at their house ( ′v‵ )

(1 edit)

Yes, even tho it say i unlocked Mio's second and Hana's first corruption event i never get a scene or an option for it thats why i ask.

Edit, found Mio's event.

For Hana's first corruption event, you need to sneak into her room when she is there while her lust is less than 5 but more than 1

(1 edit) (+1)

Any plans to do things with Tora's group? I feel like since their models are so detailed and they're a group that keeping them as sides would be a pretty big missed opportunity, and they're definitely my favorites too :P

(+2)

Currently, no. They will show up as cameo like girls from other group, but right now I would like to add more girls to explore other form of control first  ( ′v‵ )

I just finished playing through the most recent public update, and wow, I am so excited for what's coming up next. I initially was interested because of the hypnosis stuff, but honestly, the story has me totally hooked! The whole premise of the setting and the mystery driving the plot forward is really interesting, and seeing the girls living their lives and suddenly having to deal with the supernatural really lets their personalities shine in a natural-feeling way! 

*MASSIVE WALL OF MAJOR SPOILERS AND THEORY MAKING FROM HERE ON OUT SORRY*










Given what we learned from this update about the demon, I think it's safe to say that that dark weird energy that's covering Lust's energy belongs to the demon from the time that it possessed Lust. Because Lust's energy is basically tied to the demon's, does that mean that everyone we mind control is getting part of the demon's energy too? If that's the case, would the demon be able to possess them more easily, or perhaps affect them mentally in ways similar to Lust's corruption? In Negotiation, it's said that the villagers all started to behave erratically with Lust seemingly being the source of that effect; that seems like the demon's energy corrupting them, sort of piggybacking off of Lust's energy being used on them. And Lust didn't seem to do anything sketchy to the villagers beforehand, he was just generally being a chill dude, so did the demon's possession make him start mind controlling people around the village to feed Lust and the demon by extension? If that's the case, then our continued tendency to control people is likely due to the remnants of the demon's energy in us. That might be affecting Lust's personality as well, who feels a lot more blunt and to-the-point than his laid-back, almost joking personality in the past.

Then, once the demon became strong enough, it could've latched onto Hikari and fed off of her energy. We know that she hasn't been up to much for the better part of 300 years, probably because her energy is so incredibly strong that the demon can't really "possess" her, more so just tag along biding its time. Gloria even said that she met Hikari within the last year, and she seemed totally normal. The demon's energy is probably starting to take a hold of her now, which is why she's just now starting to go after the remaining seals. I don't remember if she weakened Lust's seal enough for us to start to slip out and be able to control Ai (I think it was mentioned that her energy was there, I have to double check), but she fucked up the painting enough for the demon to mess with Gramps through it on the other side of the world. Now that the third seal's broken, the demon is able to slip out more and interact with more people, possessing Yurie, who then went on to get poor Rin and Eri (also god damnit Kiyo, you had one job!).

Either way, going forward, I'm really interested in seeing how the girls take all of this. They're probably not gonna know the whole story for a while, but Hana getting possessed by the Lizardman fucked her up big time and seriously strained her relationship with the others. Now, Rin's being straight up possessed by the big bad and being uncharacteristically cold to Eri. Lord knows what would happen if Ai got so much as a whiff of the demon's energy with how weak she is and how much of its residual energy it has. There's so much drama to be had, the anticipation is killing me! (But seriously, what a dick move by the demon forcing Rin to be besties with a stranger and screwing up her relationship with Eri. That even makes it more suspicious when the others notice how distant they are for seemingly no reason. The demon kinda fucked itself over with that one when it doesn't seem like that was necessary. Perhaps it's becoming too overconfident now that more of its seals are being broken?)

Anyway, needlessly long, sleep-deprived rant aside (it's almost 4am, fucking kill me), you've got yourself an incredible story, UnusualFish! I'm really excited to see what's next in store, both in the story and gameplay! Hopefully MOMMY Mari can get some love soon, she seems so sweet but we never get a chance to interact with her one-on-one. Just make sure you're not pushing yourself too hard! 

Also, I forgot to mention, but that last jump got me good, you fucker >:c (positive)

I was actually waiting for you to post your theory on Discord first before I reply, but since it has been a few days, I probably should just reply here 

I can't really say much because of spoilers and stuff, but I just wanna point out that the new villain isn't the main one, just another side antagonist like Kiyo. She isn't possessing Rin either, just brainwashed her  (′v‵ )

Other than that, your theory is really fun to read haha, be sure to post it on Discord so other members can theorize!  (-ω-ゞ

Question for the devs. I've heard the next hikari quest or the main story is in v0.7 right?

Yeah, it will take a while  (-ω-ゞ

okayy, I guess I'll have to wait until the next main quest and play again. Interesting story btw, it's a really good visual novel. Keep it up! 

Hey boss i said it before and iam gonna say it again your amazing with story

Thank you buddy  (-ω-ゞ

Aparte de Gloria habrá evento con hana y Ai porque hasta ahora estoy sin palabras ya que la historia me preguntó que pasará con el demonio que poseyó a Rin estoy impaciente 👍👍👍👍👍 

¡Todas las chicas tendrán su turno en el próximo ciclo de actualización! ¡Por favor, espérenlo con ansias!  (-ω-ゞ

Ten lo por seguro después de este tipo de historia son las que más me gustan 

(+2)
 *Spoiler*

Girls: no you shouldn't go after the seals its a bad idea you could get hurt or worse

Girl: but I need to I can't let this happen 


Two seconds after me and my bros are told not to touch the seal: me: we broke the seals now we do this.

My bros: okay

This update made me more anxious and wanting to play even more, the funny moments of Hikari or this ending were for the best parts, great job  😎👍🏻

When will you release an update for Haru (Hana's aunt) because for me she is one of the oldest and also for me she is the most forgotten 

and in the future we will have some kind of union of powers, for example: violet's possession power + mc's control power (lust) or lily's power + gloria's power??? 

Thank you for your kind words! Haru's update will be in v0.6.7, please look forward to it! 

Violet's power and MC technically already happened in her quest, and I have no idea how Lily's power combined with Gloria would work  (-ω-

Is Hikari a yandere

Nah, she's a kuudere, I think

(+1)

The game just gets better with each new version. Congratulations to the developers.

I'm having trouble playing the Corruption Mode with Rin. Can you help me with this?

I agree! 

on what part of Rin's curruption are you having trouble at?  You can develop her lust on places she was available and you can see the curruption scenes. on the beach every Saturday - mornings 

(1 edit)

Oh I didn't know that, I just kept fucking her to build her lust. I fuck her 31 times in total only because I didn't know where the 1st corrupt scene was.

It took me a while  to find it too XD, level 1-4 lust is  1st curruption, level 5 lust and above is 2nd curruption (as of now), you might check both scenes. It does sometimes offer a different scenes. 

beach 🏖️

Thanks for the tip.

But I honestly thought that Rin's first corruption is very hidden. You have to look for her on the beach on weekend mornings, spend the morning swimming with her and her students, and only after that does the corruption scene really begin.

It's cool that the scene of them spending the morning at the beach starts a little differently, with Lustful Sin finding Rin a little flushed and agitated, and even more so after swimming, in addition to following her home after leaving the beach. After that, Rin's corruption scene is great, but the process to see it is complicated. I want to see what the second one will be like later.

The corruption of the other girls is so much easier to see, because you just have to go to their houses when they are there. My favorite is Sara's first stage of corruption. Seeing her getting fucked completely asleep satisfies my somnophilia fetish.

Yes i find it somewhat different, as first and second curruption was normally happens on each of their houses.  

Level 1-4 lust is 1st curruption, level 5 lust and above levels is the 2nd curruption. Happening on beach too. Have fun.

Is the download speed extremely slow for anyone else? 14Kb/s isn't my conection speed, I had another itch game downloading simultaneously and it went 80Mb/s

so I have a question.

sin inseminates these girls an awful lot in my "other" playthrough.

is there even a risk of him making them pregnant?

or is he canonically infertile?

he's a spirit

fair enough.

Tengo una pregunta como desbloquear la corrupción de kiyo hablé con violeta pero  no sé mucho de inglés 

(+1)

Lo siento, pero el evento de corrupción de Kiyo aún no está en el juego.

Ok

Any F/F?

Yes

Habrá otro evento con gloria es mi waifu favorita.

Yes!

what is everyones sins because i forgot

Ah, you can check their profile in the love status for it

does anyone have a completed 0.6.4 save? i somehow lost mine to a glitch.

We got some in the Discord server ( ′v‵ )

Is there already a new update? If there is, where's the link cause I can't find it. If there is not then when will it be released?

3 days more (depending on your time zone) . The release date was 14 days apart from the previous. 

This comment may seem a bit silly lol, but, when I download an update while I have the previous version of that update will all the new content in my save be transferred?, Or else do I need to go into lustful's archives, pull out my save, uninstall the old version, and insert my save into the new version's archives?, I would appreciate it if someone would answer me.

On Android? Yes, it will automatically transfer the save file 

Thanks man 😭😭

What is the music in Kaede quest called, when we get the flashback of marisa

It's "I want to go home" by Eldritch Grim!

(+1)

Do you plan to have NSFW scenes with Wrath and the other sins that don't have character paragraphs or no?

(+2)

Wrath is a no, the other sinners is yeah

(+2)

Quick suggestion: Since we're able to use Lily's energy, PLEASE make it so we can use other's energy too. I don't know if this is already planned, but I feel like it would be awesome if we were able to gather more abilities over the course of the game. Especially Violet's (my G.O.A.T!)

Anyways, great game. I've really enjoyed my time with it.

(+2)

Sure, but the rest of them is not usable in sex tho, I have no idea how Gloria's matter creation power gonna work in that case  ( ′v‵ )

(1 edit) (+2)

For Violet's, you could do some things involving "male in a female body" by possessing the girls, leading into sexual scenes about exploring their bodies and using toys/lesbian sex from their POV. 

Something like "possess ai > explore her body/masturbate, use toys, or go to hana and mind control for sex". Or, heck, depending on how you implement it, you could leave "your" body behind to use for sex while in the girl as another option. 

This could also lead into some interesting non-sexual plot situations for the story, like trying to stealth or pass as another person for a while. 

For the others, though, I've got no clue lol. Only thing I can think of is using Gloria's ability to make toys, but that doesn't seem very interesting. 


Just spitballing here though, of course.

Violet's possession shenanigans is already in the game, kinda, it's tied to her questline  ( ′v‵ )

(+1)

Oh! I hadn't actually gotten that far until...well, right now actually, I had just assumed (since I saw nobody talking about it) that the most possession content there was, was just Violet possessing girls for you. 

It's nice to find out that the content I like the most (m to f possession) is in the game already, at least in one situation (I've only gotten to, I assume, the first one at school)

Hear me out, Gloria's matter creation (if I'm understanding it's function correctly) could be used to make toys that you can use with the girls!

Also, I understand how Violet's power is gatekept due to it being an integral part of her questline. But maybe as a reward for completing the questline, we could gain access to her energy as well? If I'm being blunt, I just wanna become the girls lol...

Quick question, does this game give you the path on which to choose (Like if I'm gonna use said powers in the game description to take advantage of people) or is it more of a linear experience and the story/MC corrupts people by choice almost immediately (Because mc is also a demon from the looks of it and I assume is kinda evil right from the start)? 

(1 edit)

There is no path to it you control people from the start although the act itself is evil the MC never really gives off that vibe. it's a great game I highly recommend💯

(+1)

Ah I see. Will be trying this out after some others that I have in queue then  I was just scouting AVN's and arranging prioritization. While it's definitely unfortunate for me that it does go to that path of mandatory corruption, I'll still try the game down the line. Thank you for the response. 

(+2)

Currently, no. But I will add some bad endings depend on your choices later down the line. No control sex scene is mandatory in the game, but that also mean you don't get to have sex if you don't control the girls  ( ′v‵)

(+1)

Alright, thank you for letting me know. Will try it soon!

I know I'll be punished for my sins 😵

(+2)

Long time fan here, and of course player. Just commenting after a while away.

This game is fun and is entertaining, but most importantly, it has story that makes me wonder what will happen and has happened.

The girls are attractive and distinct from each other. The world has lore and various locations. It can be scary and suspenseful. If you didn't come for that, that should be fine, as there are interesting things one way or the other in the story and game. It is good.

I have been worried about the fate of several characters and have been glaring at several things that leave me worried for the lives of some who I had thought above danger. So again, there is definitely suspense.

I hope to see this game completed to perfection some day, it has not disappointed. That and I feel this protective urge to defend the girls after the most recent incident in the story. UnusualFish you have out done yourself with every update, please don't lose that spark.

Any way, I just want to wish you well and in case I miss the chance, I hope you have a wonderful holiday(s) and end of the year. Your work is amazing and you have the right to be proud of it, you count as an artist in my eyes. Please take care of your health and keep up the impressive work.

Good luck in development and in your life.

(+1)

Thank you for your kind words! Always a joy to hear people love the story haha, make all those time banging my head into the wall to figure out what to do next worth it! I hope you have a great holiday too, please look forward to the next story update! 

(-ω-ゞ

(+3)

SO ADORABLE.

(+4)

we must protect her at any cost!

To be honest, the ending of version 0.6.5 made me very eager to see the following story. I even regretted updating the game at one point because the story was interrupted! So if possible, could you please let me know if the subsequent story will be updated to version 0.6.6? Thank you, this is very important to me (my English is not good, so this comment was written using translation software, thank you to the author)

(+1)

Sorry, after v0.6.5, next story update will be in v.0.7.0 ( ′v‵ )

Okay, thank you. So I'll have to wait for a long time(TAT) ,However, thank you very much for creating this excellent game!

will there be impregnation?

(+2)

No
