History VisualNovel / Demonbane

Kurou Daijuuji is a poor detective living in Arkham City ([[VideoGame/BatmanArkhamCity no, not that one]]). A center of both industry and [[LovecraftCountry eldritch lore]], it is home to Miskatonic University, which Kodou is a cornerback student of. The city was built up and is run by an industry group and family dynasty known as the Hadou Financial Group, led by Ruri Hadou, who works to protect the city from the forces of darkness. Her main enemy is the villainous [[TheSyndicate Black Lodge syndicate]], led by the charismatic [[BigBad Master Therion]]. The [[WhiteHairBlackHeart white-haired]] Beast of the Antichrist, he is the most powerful sorcerer in the whole world, and his nihilistic outlook shapes the group's destructive goals.

One day, Kodou is asked by Ruri to search for a magical grimoire. As Kurou searches for the book, he unexpectedly runs into Al-Azif, a pretty girl who turns out to be the grimoire Kurou is searching for. While being chased by the Black Lodge, Al forges a contract with Kurou, bestowing him with powerful magic. Soon afterwards, Al also activates the Demonbane, a Deus Machina owned by the Hadou Financial Group, to combat the mechanical menace from the Black Lodge and Therion, who seeks the power of the grimore for himself. With this, the war between the Hadou Financial Group and the Black Lodge begins...

* Zanma Taisei Demonbane: "Demon-Slaying Great Saint, Demonbane", the original Visual Novel.

* Do Marini no Tokei Demonbane: "De Marigny's Clock, Demonbane", a Dr. West-centered interquel/prequel novel, telling of his life before coming to Arkham City, as well as dealing with the time-warping artifact known as De Marigny's Clock, one of Al's lost page sets, during the original visual novel's story.

* ConvenientlyEmptyBuilding: Even though Dr. West rampages through Arkham City with his giant robots and cause massive collateral damage all the time, he never seems to actually kill anybody, so he's LaughablyEvil.

* AllThereIsToKnowAboutTheCryingGame: The series has one of the most ludicrously, infinitely powerful {{Super Robot}}s ever conceived in it. This is pretty common knowledge among mecha fans. Now try to find someone who knows ''anything else'' about the series.

** In the prequel novel, Demonbane appears as the "[[http://outskirtsbattledome.wikispaces.com/Mecha+Profile+-+Demonbane+%28Gunshin+Kyoshuu%29 Gunshin Kyoshuu Demonbane]]" (War God Demonbane), particularly notable for being '''the''' largest mecha in fiction, even larger than the [[Anime/TengenToppaGurrenLagann Super Tengen Toppa Gurren Lagann]]. It grows so large that it ''pops'' the universe it's in, and accidentally destroys other universes by ''brushing against them''. Of course, its ArchEnemy "Gunshin Kyoshuu Liber Legis" (War God Liber Legis) is just as gigantic and powerful.

* RetGone: After Master Therion's defeat, [[spoiler: he is retroactively erased from history, and since he created the Black Lodge, it also ceased to exist (though Doctor West, being Doctor West, is still wrecking the city with Giant Robots).]] Considering how much damage Black Lodge did to the world in the final chapters, [[spoiler:(killing the ''US President'', wiping out the entire First United States Army, and sinking much of the world's combined navy, among many others)]] this is definitely for the best.

* Kishin Hishou Demonbane: "Flight of the Machine God, Demonbane", the sequel game, with a linear story and player-controllable giant mecha battles.

* TomeOfEldritchLore: As noted above, the original copy of each grimoire [[MoeAnthropomorphism appear as a young girl]] instead of a book. The artist actually has design [[http://img.photobucket.com/albums/v629/Kuruni/Girl/tomes.jpg human version of every tomes used by Anticross]] as well, but none of them appear in story[[note]]From left to right: The Book of Eibon, De Vermis Mysteriis, Cultes des Goules, The Golden Bough, Cthaat Aquadingen. Not pictured: Celaeno Fragments and Unaussprechlichen Kulten.[[/note]]. Considering how much of a sick fuck some of the Anticross members (most notably Tiberius) are, though, it's probably a good thing they never showed up in the game.

* MindScrew: Al's Bad Ending. Seriously. [[spoiler: Also one of the ultimate powers of the Shining Trapezohedron, which is to summon every Demonbane "that ever existed, could exist, never could exist, and never existed." Don't try to think about that one too hard.]]

* {{Lolicon}}: Makoto, one of the BridgeBunnies, has an unhealthy degree of lust for Al.

** The bad ending, [[spoiler:Kurou becomes Nyarlathotep's plaything. Trapped in a timeloop, he lives in the world that became an EldritchLocation after the the destruction of Shining Trapezohedron. At the end of each loop, he will meet Al but never get a reunion with her.]]

* AnachronismStew: Even though the story took place in the 1930s according to the afterword of the novelization, the United States somehow already has ''nuclear missiles''. Justified, since Demonbane takes place in an AlternateTimeline where alchemy was proven to exist and became an established branch of science.
