Rondo Duo – Yoake no Fortissimo

Rondo Duo - Yoake no Fortissimo

A rumor was circulating about an after-school devil.

Its true identity was students whose forbidden impulse is awaken.
“”From a best friend to a best friend””. The desire was infectious.

There is only one way to be free from it.
That is to have a sexual intercourse and inject the seed of desire into the vagina.

The want that comes from deep in the body. The “”new instinct”” arises.
That is something that erects under the skirt.
Its need for pleasure targets her close friends…!!

Senior and junior students and best friends… all of the girls are captured and penetrated.
And they wander in the school as the next after-school devil.
The curse is all over the school. Most of the students experienced it by then.

The order of the school was maintained only by their feeling of shame.
Their sin was regarded as a rumor and their daily life continued as if nothing has happened…

  1. Is this game still able to be played now that Flash is gone? I really want to try it out, but I wanted to ask before I go through the effort of downloading all 50 parts…

  2. Tried a little bit of everything on my win10, set system locale to japanese obviously, trying to turn hardware acceleration off doesn’t seem to do anything and it’s still giving me an error or a black screen. Did anyone manage to get a solution?

  3. question is this down load in english cause i want to down load this on a mac book air but i dont want this to be wrong with some mechanics or language issues

  4. If there are 50 parts and there’s the thing where you have to wait 5 minutes to download the next part. So, 50 times 5 is like 250 and that in all is gonna take 4 it worth it? *wipes impatient tear*

    1. You can, of course, invest in buying “Internet Download Manager (IDM)” and buy one week of premium from the storage hosting site and it takes no more than two minutes to fully download. IDM is perhaps my best investment as a longtime anime, manga and gaming enthusiast. If you are truly unable to afford it or do not want to purchase it you can easily find cracked versions on youtube or elsewhere; additionally, there is a free trial which will no doubt illuminate how powerful of a resource it can be when it comes to lightning speed downloading. To clarify, this is meant in no way as a means of solicitation as I had previously stated it can be acquired as a free resource through various methods.

  5. I got it to work the first time and then quit. Then 3 months later it’s not working – the problem is the title bar for the resolution settings is still in English, even though I installed Japanese as a second language in Windows 10’s Settings app -> Region & Language.

  6. For those intimidated by the 50 files that need to be downloaded; it’s absolutely worth the time. This is easily the most impressive h-game I’ve ever seen. It uses well a animated and detailed 2.5D art style, has full voice acting, and has a surprisingly solid soundtrack.

    There seems to be a bit of trouble with the black screen and cursor. As it’s been said before, you NEED to first open up “Rondo Duo – Yoake No Fortissimo.exe”. This won’t let you actually play the game though. It will open a new window with three words on the right side of the screen in japanese. These are screen resolutions. The top most selection is full screen, while the other two are window mode sizes. After you select your size, the game will try to start up, but will get stuck on the black screen with the cursor on it. Go ahead and close this window. All that stuff was to set a resolution size for the game, which will carry over to the patched game exe, “Ron2.exe”. So long as you set the resolution before trying to run this exe, the game should run as normal.

    If you didn’t set it first, you may need to remove the game and unpack the rars again. The game also uses flash, so making sure it’s up to date may help as well.

  7. Totally worth it the download, 1d non-stop whew.
    I’ve seen people talking about black screen with rotating cursor and mentioning Ron2.exe
    The thing is, you MUST first open the file named “Rondo Duo – Yoake No Fortissimo.exe”. []
    It will pop-up a windowed screen ASKING which resolution do you want to play with []:
    1.- Full Screen
    2.- Full Screen 642x532px
    2.- Windowed 642x532px
    After you had selected the resolution of your liking, you can proceed to use Ron2.exe, and it will always open the game with the selected res. That’s it.
    If, by any chance you get a Japanese error when trying to open the first .exe, you probably need to change your PC locale to Japanese; if you don’t know how to change it, give a quick Google search or read the FAQ []

  8. I give up I have been trying for hours, nothing is working to get it to play. I keep getting the cursor on the black screen.

  9. Im on Windows 7 trying to run the game ,but Ron2 its only a black screen and a rotating cursor ,i tried admin ,running the “Rondo Duo – Yoake no Fotissismo” (gives me a japan error) ,turning off hardware aceleration and the ROD2.ini


  10. @Drake
    Yes I’d like to know this too.

    Is it censored? I downloaded this game from somewhere else but it’s all censored and not just a little, a lot.

    There are tons of files here and I really don’t want to waste my time if the game has no uncensored version. Patches or do I have to re-download an uncensored version? Does an uncensored version even exist?

    Many thanks!

  12. Actually a really nice VN. It’s not a game, and it is running on FlashPlayer, using the “Ron2.exe” application. I am on Win10, and administrator. Full-screen started as default, and worked fine in the center of my 3 screen setup. The controls are a little weird: Mouse to top of screen for Save/Load. Mouse to bottom to skip movies (Keep your pointer away from the bottom, if you actually want to read the text) I found no way to rewind to catch something that went too fast. Sometimes an option shows up to adjust sounds, but they return to default on the next scene. “Esc” closes the VN.

    Extra, or Post Storyline content is found on the final screen, where it seems like there are no options but to hit “Esc”, and end the VN. Select each of the Highlighted letters in the scripture shown, any sequence, and the name Katerina will appear above, then the VN continues.

  14. For black screen & spinning cursor problem:
    Create a text file in main folder and type in FullScr=0 and save as RON2.ini

    1. And if creating the text file doesn’t work? I made the RON2.ini text file and i’m still getting a black window with rotating cursor.

  15. I am just getting a black screen with a rotating cursor when I try to run the ron2.exe. I tried to run the Rondo Duo – Yoake No Fortissimo.exe but it just gives me an error in japanese. Can someone please help me get this running?

  16. Nobody really talked bout so im gonn ask

    Is this english subbed?

    As beautiful the animation could be, I want to know the story

  17. For+some+reason+i+dont+know+why+but+when+7ziping+it+its+says+1,37-40,+and+50+parts+are+brocken+but+i+fully+downloaded+them?+So+is+it+just+the+file+can+someone+fix?

  18. i got the game to run through the first animations of thinkerbell and the other one but after that its just black, any ideas?

  19. Can I know where I can find my save data? I always lost my save data when I restarted the laptop.

  20. i’m use win10, i play well at chapter 1, then I pass chapter 2 and it appears only a white screen, i can’t play chapter 2 and another chapters, can’t save game, go to “music” appears white screen, when appears white screen i press the button “Esc” & out the game, how to fix that problem @@?

  21. One word. Epic. Storywise, it is short and nice. Gameplay, wow. As a Nukige, this is one of the best I’ve ever played. I wonder when the sequel will be translated, can’t wait. If you don’t care about the size of the game and want to be entertained, do not hesitate.

    1. this is the best eroge i played, the animation, voice acting, wow ! any other good game of that quality to play?

  22. When i download any of the parts there will be a network error, happens everytime i try to download anything from this site. Any solutions?

  23. how do i access the extra? 😮
    can’t find it anywhere despite having finished the vn
    thanks :))

  24. I am using Windows 10 and when I start the game only a blank adobe page with a rotating cursor appears. What can I do to fix this. I have tried compatibility mode and it didn’t work. Please Help.

    1. I had the same problem and solved it by turning off hardware acceleration in my flash settings, Right click inside of the flash window, click settings, and go to the first tab. It should be a checkbox there. I hope that there also solve

      1. I tried it but it still didn’t work. Do I have to do anything with the files before I am able to play it? Also I am using adobe flash player 10.

        Thank you for responding to my question.

        1. Same problem here… I’m using win7 and adobe flash player 10, but when I start the game, same rotating cursor and blank adobe page…

          1. Black screen is because game is trying to launch in an unsupported fullscreen mode.

            Run the actual game first, select either the second option or third option for working fullscreen or windowed mode respectively, then run Ron2.exe

          2. “Run the actual game first” you mean : “Rondo Duo – Yoake No Fortissimo.exe” ? Because I have an error when i run this exe…

          3. What if the main “Rondo Duo” application won’t even open? I’m not getting an error message, it’s just not opening even when I run it in administrator mode.

          4. Any fix for the black screen problem? Ron2 still just gives the spinning cursor, ran in admin mode and disabled hardware acceleration, and the “main file” still gives and unintelligible error. I found I could go into the .ini file and change the fullscreen setting to 3 to get windowed mode, but that didn’t help at all. Any advice?

  25. hoq do u change from full screen to windowed? i tried alt + enter and it doesnt work, is there any other way? theres no options menu on the start screen

  26. the game’s already patched simply click the adobe icon “run2.exe” to launch the game in English.

  27. Got a doubt, is the game patched in English? If so is there a way to only download the patch? I’ve already got the game so it would save hours of downloads.
    Thanks in advance 🙂

    1. there is patch, you can search it by googling, or
      check it out the link for the patch in vndb dot org

      1. Nice, thanks for the info. One of the times I also actually have the original file. Could understand the story well enough even without translations….but I’ll definitely enjoy going through it again with translations patched in.

  28. I don’t like yuri, I don’t like futanari, hate rape, but it’s animated and I need a distraction while I wait for Sunrider DLC… at least the gore tag isn’t there. Plus, the captcha this time is “play a game”

    1. You are a fucking idiot. What retard comes to a futanari yuri game just to say you hate futanari and yuri. Get the hell out then you dumbass idiot.

  29. Hmm . . . Is there perhaps a MEGA Download somewhere? Like in ULMF? = / gota search one because that would mean one Download instead of 50 = I

  30. O.O


    This is one hell of a game. This is gonna take me forever to download.

    … Better get started then.

    Thanks as always.

  31. If this has only Yuri in it then i’ll be interested in it. Otherwise, no thanks. If anyone can tell me this is a pure Yuri VN then i’d be grateful. 🙂

    1. There is only Yuri H, no males indeed and no balls, however if you do not like girls with a certain other appendage commonly seen on males, well, then that’s that, Rondo certainly ain’t pure, in a way either.

      1. That’s fine, I consider Futanari an “advanced” form a Yuri, strangely enough. So no worries, as long as it’s Girls Love only, sick and tired of the regular “dom” by males after all and if this has only Yuri-type love in it, even Futanari, then that’s fine. Thanks for letting me know. 🙂

  32. This game seems really interesting, i would love to download it. However not only does its immense size take up 10% of my current data plan. But i can’t afford to pay for the download and it would take days of non-stop downloading to finish it completely. So i’m gonna have to take a pass on this game.

      1. It’s very heavy animated, but uses pretty bad engine, which doesn’t allow reuse of animation, and animations are pre-rendered (unlike “moving sprites” eMote system, present in latest generation of VNs), hence the huge size.

        1. Indeed, Flash is indeed teribad but it is also worth mentioning that there are a lot of H scenes with even more variations (explains why the DL sites says 500) which are not just in-out-repeat while the dialogue is so short.

          If they had stuck to the common time between CGs/new animations, then this would easily be twice, if not thrice or even four times as long and the estimated read through time is 6 hours.

  33. its funny how big the file size of this game is relative to its length. The animation is a nice departure from what we usually see come to the west.
