Osananajimi wa Daitouryou

It started out as an ordinary morning, woken up by my childhood friend. Had a good breakfast… complete with morning hard-ons. An ordinary, everyday eroge scene. Or… so it seemed. Things would never be the same from that day, as peaceful everyday life was blown to bits. An accident on a spaceship heading to earth, causes it to crash on the Prime Minister of Nippon’s office. The leaders end up in a state too horrible to see. To avoid chaos, the loli alien choose a girl who happened to be there, and to make ends meet, brainwashed all of mankind. Nippon adopts a presidential system overnight, and incredibly, a girl, my childhood friend, is the president. The world will answer to her every whim.

meant to say this for a while... it's been messing my head. but the tittle in japanese means my childhood friend is the president right? at least should be

The official title is 「幼なじみは大統領 My girlfriend is the PRESIDENT」, English included.

MzKing29 Aug 2011Reply

Well, its true, Osananajimi means Childhood friend but in almost every english subtitle it says "My Girlfriend" but hey, its english for you >.<

Hi admin. not uploaded in filesonic yet?
I am not pressuring you or anything, just wanna know

Ahmad123n17 Aug 2011Reply

yo admin , for some reason , my internet/computer can't download anything from fileserve or megaupload.

My main reason is, can admin plz upload the game at filesonic? cause that is one of the file hosting website i can only enter , would be a real help!

yo ahmad.. if you're from malaysia, then your government actually blocks sharesites like megaupload, etc.. if im not mistaken, 'MSC' or this government did that to reduce piracy.. i personally think it's bull.. to gain access back again just change your dns server to google's.. 8.8.4.4/8.8.8.8 and voila.. u can download from blocked sharesites again.. ^^

Don't ask me why I put a question mark after "Thanks". My fingers where likely typing faster than my brain could think.

Oupost Omega J24 Aug 2011Reply

I have apparently done something wrong of offended someone for the post I wrote seeking translation about a few specific lines from the installation pictures above.

I apologize for whatever I did. If you could let me know so I can avoid doing it in the future, I would appreciate it.

(PS: My above post about putting a question mark after thanks is with regards to my now absent post if anyone was wondering what I was talking about.)

admin25 Aug 2011Reply

You didn't do anything wrong - it's just that your comment contained links to pictures, which caused it to being hold for moderation, and i was offline for the weekend.

Benjamin25 Aug 2011Reply

I downloaded all the parts and the patch. Then did every thing step by step that you described however when I try to run the game I get the error ???????(syntax error). Is there a way to fix or get around this? I tried taking the patch out of the folder to run it w/o it but this didn't fix the issue.

Ceke25 Aug 2011Reply

Had the same problem, just found it out!

You have to change the system locale to Japanese (how to do here: http://windows.microsoft.com/en-US/windows-vista/Change-the-system-locale) before installing, otherwise the game won't play.
Deinstall the game with your local system, afterwards install the game with Japanese location and it should work just fine.

Kiddo27 Aug 2011Reply

i can't open the file, coz it said .mds file. i did extracted 6 parts + patch and put them in same folder, but it didn't work. please, anyone can help me?

Kiddo28 Aug 2011Reply

i'm using windows 7, is there a problem with my windows or the parts themselves are broken?

Zanna28 Aug 2011Reply

Would have been nice to somehow get a Kuon scene/ending. Especially after you play the Ran route and see the cuter side of Kuon.

MzKing29 Aug 2011Reply

i only play for few minutes and this game is "EPIC"
an Alien crash into earth,
the main character's childhood friend become a prsident,
his friend say "Reality is a Crappy game" (its Keima's line on Kami nomi zo shiru sekai),
and on flashback he says "What kind of eroge is this!?"

This game is Epic 9/10

~KnockingHeart~04 Sep 2011Reply

lol!! i'm still in the middle chapter i guess. well, i guess i will into GOD MODE now?

Seven Points On Ten24 Oct 2011Reply

The artwork in this game is really some of the best I've ever seen in an eroge(I really can't wait until admin uploads the Jast version with all the uncensored goodness). The only bad thing I could say about this game is that the endings really felt rushed and lack-luster; but then again, the game itself seems to be a fourth-wall breaking comedic romp so one can't really complain too seriously about the absence of realism. Oh well, I'd still recommend this game to anyone and everyone who has the hard drive space for it. x]

Takoyaki05 Sep 2011Reply

Sir Admin, I've installed the game but actually syntax error appeared when I running the program/launcher.
Any ideas/suggestion? Thank you.

HeroineSavior06 Sep 2011Reply

Here, there's only one word for this game : AMAZING!
Both character's design, background music, and story (it's a perfect comedy-romance-harem combination) are absolutely amazing!
This game has something that other games don't have.
I hope this game becomes anime or manga at least, because THIS IS THE BEST EROGE GAME I EVER PLAYED!
Thank YOU!

Lilienette10 Sep 2011Reply

Can someone tell me what to do after downloading the game? I can't install the game properly (i have change my locale to Japanese though)

Lilienette10 Sep 2011Reply

Btw i can't extract the part 1 because it is always stop on 80% i did redownload the file but it still like that. how to fix that? thx before.

Alcot11 Sep 2011Reply

Oh, anyway, I did finished the game with irina's route. It was wonderful. It moved my heart. Now, I wanna take another route to Yukino/Ell/Ran. What choice should I take to access their route? Anyone who complete 100% of this game, help me please!

Seven Points On Ten24 Oct 2011Reply

Basically, it goes like this: You have the choice of going down Yukino's route, if you don't get jealous, the route is passed up and then the lunchtime scene where you have the option to praise Irina's cooking comes up; if you don't praise it, your next chance at a route will come when you are at Ran's part-time job where you can look at her or the panda, choose the panda if you want to ignore her route and get to Ell's route, in which case, of course, you compliment her.

Mu-Ha-Ha-Ha-Ha!!! As expected from me! I can see THE ENDING!

Phanteon15 Sep 2011Reply

Hi guys.
This question may be very stupid. but i just recently got windows 7. i dont know what the game folder is... is it the cd rom installed or the alcot folder?
Sorry for being such a newbie.

DokiDoki15 Sep 2011Reply

Hi, first you have to download DAEMON Tools Lite, install it. Then, you must download all of parts file (.rar type) and extract them into one file. Afterwards, see FAQ for more informations (how to mount image using DAEMON & install the game itself).

GamerZ17 Sep 2011Reply

Ryan29 Sep 2011Reply

admin29 Sep 2011Reply

You didn't change your locale to japanese before installing the game.

Ryan29 Sep 2011Reply

i did

Hartley07 Oct 2011Reply

The game's working perfectly, I pasted the patch into the directory but for some reason it isn't working. I tried restarting and I'd been running the game as administrator. Please help me?

munchy08 Oct 2011Reply

zzz... I'm tired of solving this myself. umm. is Ran route translated? damn it i'm stucked on some loop in her route.. plss anybody HELP~~!!

Crazyblue24 Oct 2011Reply

Hey i had a problem with Rans route as well, these are some instructions someone left in a previous comment which helped me past the bug.

there is a bug in Rin route..
1. you can avoid this by disable the translation patch(delete the file or change it file extension)
2. load your last game before you encounter Rin’s bug without eng patch, then play until you finish the event (marked by picture like this http://i986.photobucket.com/albums/ae341/CrossDy/CheckPoint.jpg)
3. save your game, put the english patch to you game folder then load the game

Seven Points On Ten24 Oct 2011Reply

Just remember the bug occurs twice. Both times occurring in the confrontation with "Terminachan"(lol).

4nim3w4tch3r13 Oct 2011Reply

i finished Yukino and Irina's Ed, so im now going for Ran-neechan's but then i get stucked at the part when she defeated Kuon-san in a Mahoushoujou Outfit. can anyone help me out here?

munchy15 Nov 2011Reply

its a bug. read the reply from my comment above... try it. it might work on you

Absolute15 Oct 2011Reply

PLEASE, ANSWER ME : (.

I have a problem with the load/save system.
Everytime i try to load my saved game,it just put me back to the start of the game(Where she makes the speech)...Any idea how to fix this problem???...

Thank you for your time.

Seven Points On Ten24 Oct 2011Reply

This game has an rpg like save/load system; rather than loading directly from where you saved, it seems to load from the start of the scene you saved at. Also... as for saving at choices... you don't need to worry about that until you get to the lockers scene.

chrouble18 Oct 2011Reply

what file is "game file" exactly? I tried putting it in alcot but it didnt allow me, then I tried to put in the file with the mdf program that needed the mounting, but none of this turned text to english in the game. I DONT KNOW WHAT TO DO, I WANNA KNOW WHAT THEY SAY.

chrouble18 Oct 2011Reply

I mean "game folder" ><

Seven Points On Ten24 Oct 2011Reply

I have had a problem loading previous saves before, but it was because I closed the game improperly after having made the save(terminated it via Task Manager). Just start over from the beginning and skip until you get back to where you were and try that way. There really aren't that many choice in the game overall, and only one important choice for each girl for their respective routes. Hope this helps...

You don't have to be concerned about that, just choose option 1 in the 3 choices, and you're right by the way in the second picture, it just tells you if you want the shortcuts placed that's all... Hope that helps :)

Animus Et Anima18 Nov 2011Reply

Well, if you are still persistent on understanding image 1, it just asks where you want the save file location to be, first option is where the game directory is, the second one is your documents (i.e. My Documents or something like that), third one is outside of the directory which is where your Application Data is... there you go

Thanks a bunch.

I like to know exactly what my computer is doing at any given time. It's hard to know that if I don't know what choices I'm selecting.

boss_al20 Nov 2011Reply

Hey, i'm just install it
when i run osana.exe, the game crashed and notify "?????? syntax error"
help me please !!

Animus Et Anima20 Nov 2011Reply

I don't know if this helps or not, but probably there's a problem with your PC's local... Is it set to Japanese? If so, then try to set it to Japanese or use AppLocale to run the program...

Hope that helps :)
