Deus Machina Demonbane

Arkham city is a bustling hub of commerce and industry, however Arkham is also a center of eldrich lore: home to Miskatonic University, an institution of higher learning with one of the most complete libraries of arcane literature in the world. In the span of two generations the town was built up to the status of prestige it now commands, an expansion helmed by the Hadou Group, an industrial complex and family dynasty currently run by the young Hadou Ruri. She pursues the peace and prosperity of Arkham diligently, against the forces of darkness threatening to plunge the city, and the world, back into a second dark age. Among the most sinister threats to Arkham City is the evil Black Lodge syndicate. Led by the charismatic Master Therion, his nihilistic outlook shapes the group’s destructive goals: with a circle of powerful sorcerers at his command, the potential for sowing chaos in the city is unmatched.

Former Miskatonic University Magic Academy student Daijuuji Kurou knows little of grimoires, but what he does know terrifies him – enough that he left his university life behind, and now practices a failing detective business in the shelter of an orphanage in a quiet corner of Arkham. But just when he thought his Academy past was buried, it catches up with him and pulls him back into the dark shadows of the occult: Hadou Ruri herself appears at his door with an offer he can’t refuse. The only way to combat the Black Lodge’s growing magical power is to find, and retrieve, a grimoire with the power to activate the mightiest Machina of all: Demonbane. The quest to find this forbidden tome will change Kurou’s destiny… forever.

    • Zellrang says:

      thats… kinda hard to find actually… but there IS a way to find it…

      1.check the “show hidden files”…
      2.enter “users” file
      3.enter “your computer/laptop name” file, for me its zellrang 😛 in other words DON’T ENTER “default” and “public”, nothing really happened if your enter though, its just not there.
      4.enter “AppData” this is the hidden file X3
      5.enter “Roaming”
      6.lastly, find and enter “Nitroplus”

      • Zellrang says:

        oh,yeah leave the”9999″, “common” and “images” alone… other than that three is all save point, check the number of the save point

    • Zellrang says:

      just found the EASIEST WAY… after you open it just press F1… it automatically open the folder of the save point… X3

    Does anyone have problems with voice in this version?
    I can see that there is a separate voice patch.
    When I play the voices stop at some point.

  4. white rose says:

    Ihave a serious problem with Demonbane. The texts of this game are not well align which make words often split in two and other also overlap with some words. This make the game absolutely UNREADABLE. I have scearh for weeks for a solution but no one seem to have my problem. I am beginning to be very FRUSTRATED. Can anyone can help me please?

  5. Corbane says:

    I actually did download it, but when I tried to extract it, I got a message saying one of the files we corrupted t_t. And I downloaded using both Filesonic and Fileserve at the same time, so I basically just cannot tell which part of the rar file was at fault or if it’s one of the two locations that caused the problem. Anyone else went through this trouble.

  6. Vampir0 says:

    At 1st fight Demonbane vs. Doctaaaaaa West on drum-like robot, just when they use Lemuria Impact game just shutting down…=( Does anyone know how can I avoid this?

    • admin says:

      That’s when movie is played. Install CCCP codec pack.

      • Yurusaki says:

        Admin, I am having the same problem as Vampir0. I have the CCCP codec pack and I ran the game as an administrator to be sure (I also enabled all the options for CCCP, in case that might resolve the problem) but the movie where Demonbane uses the Lemuria Impact won’t play. I am using the voice patch, could some strange interference between the patch and the game be the reason?
        Any help would be much appreciated, and I thank you very much for your continued efforts with this site.

        • Yurusaki says:

          Just an addendum to my previous post, I do have Japanese support and I am running an XP OS.

          • Yurusaki says:

            Admin, I looked at other comments and was able to find a fix to getting past the Lemuria Impact movie, but now I’m stuck at the second Dr. West fight. Again, I can’t play the movie, all I get is a black screen. Can you help me please? I greatly enjoy this game.

            • Miyabro says:

              For people stuck on getting past the movies, download CCCP then go to ffdshow video decoder configuration and put the demonbane executable as an exception ( Don’t use ffdshow in: (select .exe file)

              This solved the issue for me.

              • Raiden says:

                Yeah, that fixes it. With the latest codec pack you don’t need to change any settings, just have it installed. will have the latest version with a one-click install and that worked perfectly for me.

  7. GJ! says:

    Do you guys know any ways to close someone voice in voice selection?

    • mysterion says:

      Seriously, is there any way to disable voices for particular characters?

      I’m currently at the start of Ch. 2 and if I have to keep hearing that annoying protagonist’s voice for the rest of the game, I may not last long enough before finding sweet relief at the hands of death…

  8. xphantonx says:

    hi, i downloaded the parts and extracted them.
    then i opened the file db_usa.exe and the game went well without any problems, but when i clicked “extra game” (or sth like that) the game window closed.

    now everytime i double click that file to open the game, the mouse point show that the game is opening but nothing happen, only if i click a lot a window is shown but it close afterwards.

    i deleted the files and extrated twice and checked that the parts were fully downloaded

  9. Yurusaki says:

    I think I found a fix to the black screen problem (movie won’t play even with CCCP). There’s probably some weird file mismatch error, so if one file isn’t working, it is necessary to rename it as DEMON_DEMON. Then just un-rename it afterward.
    For example, in the first Dr. West fight, switch the filenames mv_lemuria and DEMON_DEMON. Then switch them back. I assume this will work for other parts as well. In the second Dr. West fight, I switched DEMON_DEMON and mv_summon8al and it worked.
    Hope this helps.

  10. Sgrumbledore says:

    I’ve downloaded and unpacked the game, but after i click on

    the game exe/start i get this message “daemon bane usa has

    stopped working, a probloem may have caused it nont to


    How i can fix this problem?

  11. krocolatos says:

    admin i want to ask something, on your other site “” you have link for demon bane voice patch. just want to know, is it useable for this version? because the pc version only have half of the dialog voiced.

  12. RANDOM_HERO says:

    OK ok i understand this patch has not all the voices but people said h-scenes are
    Problemm is the first h-scene (the one with the spider woman) is not voiced, am i the only one?

  13. Shiryou says:

    I have a question. This is English version right? Can I change lanquage to Japanese?

  14. MrBear says:

    For some reason, it will not open for me…

    Could not create Dirct3D Device.
    Please check the following

    Display Mode is not in full color.
    Your graphics board is not Direct X 9.0c compatible.
    Your graphics driver is out of date, or malfunctioning.

    I have that version of Direct X and my graphics card, ATI Radeon HD 2450, should be capable. Any help would be appreciated.

    • RANDOM_HERO says:

      As far a i’ve heard it’s either you have not all your drivers uptated/missing or your video card isn’t compatible with game.
      For first one i suggest update directx 9 to a newer vercion(btw most of people having this problem had directx 9 running) if i’m not wrong microsoft has updated to 11, you can download it for free from their page.
      If it’s the second one well, give up.
      Oh also try the well known reinstall or restart computer, sometimes they work.

      • MrBear says:

        I have XP so 9 is the latest version of DirectX I can run. All the drivers should be up to date…

        • RANDOM_HERO says:

          Pffffffffff thats why XP has allways being a !@#$%
          Ehem! sorry about that but XP if far away of my limited knowledge.
          I suggest you google it but be aware, you will find very complicated stuff, sorry for not being of any help!
          BTW ATI and microsoft are like dogs and cats so it has always had trouble with direct x, if it is a desktop you have why not try Envidia or install vista, it’s a thousand times better than XP and 7 IMO

  15. mikez says:

    this game is odd… i saved near the beginning and played for half an hour… the power went out and i had to go again. but the story had changed… why did that happen? i cant get back to the story i was on.

    • burabura22 says:

      because this is visual novel, the strory line will change if you do something different from what you do before

  16. Whoa says:

    hmm. the voices stop working at chapter two for me? does anyone else have that problem?

  17. Hachi says:

    This game is a work of art, Thank you deeply admin, and keep up the good work!!!

  18. kyoryo says:

    can u give me mf download links?

  19. Tenjin says:

    Okay, I feel really dumb here, but how the heck do you save?

    • lolcatz says:

      Some people have that issue with VN’s.. have you tried right clicking? some sort of drop down box maybe?

      I’m just giving you suggestions since i don’t have this game… yet.

  20. Gale says:

    For people having trouble w/ the voice patch let me clarify that it was ripped from the PS2 version w/c is an all ages version of this game. Thus h-scenes will never be voiced because the PS2 version doesn’t have h-scenes at all. This also applies to some other games in this site like FSN.

    • Raf says:

      As far as I’m aware, ONLY the H-Scenes were voiced in the PC version. Wouldn’t adding the PS2 patch add voices to everything else then?

  21. Ken says:

    tyvm for the re-uploading. ^^

  22. Lewelyn says:

    Wow-I like this game – it is inspired by the work of H.P.Lovecraft, whose stories I like very much. It is also the first Eroge in which I find really good music!

  23. UltimateMan says:

    Is the video when demonbane first uses lemuria attack(or whatever its called)supposed to be inverted?

    • admin says:

      Nope. Check your video codecs settings.

      • UltimateMan says:

        In addition to the video, the part where Kuruo summons demonbane during the second fight with Dr.West(after fighting the spider) is also inverted.

        I’m using CCCP, what exactly are the settings I’m looking for?

        • UltimateMan says:

          Ah, wait never mind. Setting the [Display Monitor Setting] to Manuals instead of Auto actually creates the problem. Videos fine after switching to Auto before the cut scene is played.

  24. Decadence says:

    I have a problem, some of the videos are just a black screen with audio. I have the newest version of CCCP, and have tried disabling the ffdshow for the demonbane.exe but that didn’t work. For some reason the first video where Demonbane is activated and enters the teleporter “rock” works but not any of the others. Any way to fix this? Thanks.

    • Decadence says:

      Apparently opening the video files with the CCCP player will run them, but the problem of running them within the game remains…

  25. Minute says:

    Do you have to change your system locale to japanese to play?
    The game freezes up my computer

  26. Reiha says:

    Thanks again admin, been waiting to play this, I’ve watch the anime before a long time ago and have wanted to play this since contents are somewhat based on HP Lovecraft’s Cthulu Mythos and being a fan of Lovecraft’s work I find it interesting to see some of its concepts in an eroge.

  27. FaustVIII says:

    whats the license code for the game?

  28. A person who finished the game once says:

    Hi readers,
    I finished the game one time and guess what I discovered? I didn’t even get 25% of CG
    it looks like I have to play it over and over,

    The story is awesome full of plot twists and interesting characters,the H content is strange (some sizes are abnormal) also the scenes are randomly voiced -some parts aren’t voiced- but there is enough voice,I only got like 40% of H scenes with my first play.
    (I don’t know if I was lucky or not,but no main character got raped maybe with a replay there will be one rape scene atleast)

    These are some advices: while skipping go to window mode,full screen may cause a crash -it will happen-

    the music is awesome don’t desactivate it.

  29. zaq6394 says:

    *may contain mild spoilers so please read at your own risk – i have tried to keep these at a minimum though*

    first off – a long game (at least judging by my standards and experiences of VNs, maybe they’re skewed). I believe there are something like 13 or 14 chapters in total, so be prepared for that. If you’re looking through the walk-through, be warned that some chapters will have multiple choices in them (especially the earlier ones) which is how I set my expectations in terms of pace, and then you can go multiple chapters without a single choice.

    second off – the H scenes are… disproportionate and relatively few compared to the length of the game. They’re not that good either to be honest, but that’s just personal conjecture. Almost all of them either bordered on or were the embodiment of sadism, which in a game that develops its characters as strongly as this one is a bit disheartening. Then again the overall motif of the game is quite dark so maybe that’s just a part of it. Towards the end I gave up on the H scenes and just played it for the story.

    third off – like others have said, the beginning of the game is somewhat slow, and seems more like every other VN that I’ve encountered – you have choices, but everything has its set limitations/boundaries. The second half of the game just explodes in terms of thought required to grasp the concepts happening in the game, which is no less than I would expect from a game based on the Lovecraftian mythos. The twists and turns further lend to the intricacy of the story, which I am grateful for. I started this off as a mere curiosity, however by chapter 6 or 7 is really drew me in and I was genuinely interested/intrigued in what would happen next. Overall story really picked up speed and held my attention.

    fourth off – the game can get quite dark. There are no explicit guro or vore scenes shown, however there are many allusions made towards that subject matter. Again, this game is based on Lovecraft’s universe so if it wasn’t dark I’d be worried, and it does a good job of portraying the primal instincts of insanity and fear in the characters/story (especially so in some of the bad endings).


    Story – first half: 6/10, second half: 9/10
    Music – 9/10 (it’s very intricate/mood-dependent, I would recommend listening to it during the game)
    CG (non-H) – 9/10 (great settings and artwork in general)
    CG (H) – 3/10 (seriously what’s up with these?)

    • zaq6394 says:

      Forgot to mention – this game has a (surprisingly) great sense of humor that helps you connect with the characters even more.

    “admin says:
    June 13, 2011 at 2:21 pm

    PC version has voices only in h-scenes, prologue and epilogue. Rest of game is unvoiced if you don’t use that patch.”

    Does this mean that, if, whenever I come across a H-scene, I switch the voice.npa file to the PC version, I will be able to get H-scene voices?

  31. Torbin12 says:

    Hmm…I dont know what I may have done wrong. I notice that in some of the comments, it talks about the exe being cracked, but I still get the License Code request screen, should I try a re-download, or am I doing something wrong?

  32. Joshi J says:

    Seriously, how the hell do I disable the main character’s voice (or any specific character voices for that matter) whenever I try to mess with the “setting for each character voice they appear to be locked. His voice is extremely grating.

  33. lui says:

    was disappointed, thought it would be a do something eroge, but its just a read and enjoy type

  34. Zwei says:

    Hey how can i turn it on in full screen

  35. Vondoom says:

    Ok… This will be my next target after I finish Ef-The latter tale. The Art seems promising but if the story doesnt hold up to my standards I’ll probably just stop half way through. I just finished Yumina the Ethereal by the way… and Oh My God That was a Tough Journey, currently on Yuuko’s chapter in Ef the latter tale and then I will be goingh for this. WISH ME LUCK!

  36. Vondoom says:

    Well, that was dissapointing… -_-… I dont know why but after finishing Al’s route… I can’t seem to find the relevance of the 2 remaining routes… The Princess’s background was kind of interesting, but yeah it didnt appeal to me very much, and the Nun…well, blow me… (no pun intended ) But hey at least Al’s route was good in my opinion, I also watched the Anime adaptation which was aired on 2006 and yeah, they really did good by choosing Al’s route, but that ending… WHERE DID THAT COME FROM O_O!?

  37. Doflamingo says:

    not bad the h scenes are krusty the dick of the main character is tooooo huge but overall it was ok

  38. Xamusel says:

    So, due to some issues with the downloading, I couldn’t get the last part of the game downloaded. My browser couldn’t even find the file to download.

    Is anyone up to solving this issue? I’m using Firefox at present.

  39. Vaz says:

    How do you turn off kurou’s voice?, I see options for them o.O

  40. New Guy says:

    Hi, part 3 of the .rar is down, could someone fix that?

  41. AnimeGear says:

    Is there a way to make the game play in Fullscreen?
    There is no option in the CONFIG to go fullscreen

  42. Jay_ says:

    I searched for ‘Mac OS X’ and this game showed up.. So is it playable on native Mac OS 10.6.8..?

  43. Wisteriatree says:

    It won’t play on my toshiba and i go to it and it refuses to play at all. This wasn’t the case when I had windows 7 but when it got updated it won’t play anymore any help?

  44. UnLimiTeD says:

    I never expected to find a VN with such genuinely unlikeable characters.
    I’m like 15 hours in, and I’ve yet to find any main character I wouldn’t feel the desire to punch if they were real.
    Still hoping it gets better but I’m not too hopeful.

    It’s seriously irritating.

  45. RuiMist says:

    How do you get the full screen to open up? I’ve tried ALT+Enter and setting the screen settings but so far nothing is working it won’t get off the windowed setting.

  46. demninjaz says:

    …I’ve been looking everywhere for a decent (read: not confusing as hell with file types like MDF and stupid crap like that, and it’s the actual PC version.) download of this game. (NOTE: IN MY CASE IT’S NOT PIRATING BECAUSE I OWN A PHYSICAL COPY OF DEMONBANE, BUT MY CD DRIVE IN MY COMPUTER DOESN’T WORK ANYMORE.) …As if I give 2 shits about pirating/downloading stuff that you couldn’t get your hands on any other way. I played it all the way through on the physical copy…(And I had the PS2 version as well…that game was part of the reason my parents made me sell my PS2…damn door, locking from the OUTSIDE.) But I wanted to play it again…and lo and behold, my goddamn CD drive doesn’t work anymore. So…yeah, thanks to the admin. And thank you to Nitroplus for making yet ANOTHER awesome VN. Why, yes. I do happen to enjoy PLOT with my “PLOT”…:3
