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…

    This will take a while to download. I’m going in Cap’n!

  2. bananaman says:

    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.

  3. J says:

    This was so damn amazing.

    It was short but oh so sweet

    • Badboll says:

      10 gig and short? That’s messed up. Oh well its no reason not to play.

      • admin says:

        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.

        • SakuraKoi says:

          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.

        • DankMemeScythe says:

          Heeey, do you know where is save on menu? I can’t find way.

  4. Gur says:

    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.

  5. Azure Rave says:

    its almost summer this has become a goal to download and thanks admin

  6. OneUglySunuvabitch says:

    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. 🙂

    • SakuraKoi says:

      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.

      • OneUglySunuvabitch says:

        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. 🙂

  7. bevill says:

    Well looks like it’s gonna take 5 centuries to download this! XD guess i better get started!

  8. JCiel says:

    O.O

    Wut?

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

    … Better get started then.

    Thanks as always.

  9. Christin Eleven says:

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

  10. Kayto says:

    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”

    • Philip Baxton says:

      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.

  11. Zufield says:

    Haha, that sure is some peak Engrish in the description XD

  12. Yak says:

    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 🙂

    • VN lovers says:

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

      • Flippin says:

        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.

      • Yak says:

        Thanks a bunch

  13. falteran says:

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

  14. unknown says:

  15. Anonymous says:

    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.

    • rasec says:

      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

      • Anonymous says:

        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.

  16. lucia says:

  17. Seichan says:

  18. jkmj says:

    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.

  19. Harasho says:

  29. soundwave96 says:

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

  31. 2kinky says:

    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.

    is this censored?

  35. Complete Nobody says:

    @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!
