--> "''This is not a tale of a hero. Those who want to become heroes are worthless.''"

'''''Full Metal Daemon Muramasa''''' (装甲悪鬼村正, Soukou Akki Muramasa) is a VisualNovel by NitroPlus. It was written by Ittetsu Narahara (of {{Hanachirasu}} fame).

''Tsurugi (劒冑)'' - These are [[PoweredArmor powerful sets of armour]] which can only be crafted by [[UltimateBlacksmith special smiths]], who infuse their own soul into it at the point of completion. Any man or woman who wields a Tsurugi is known as a ''Musha (武者 - Warrior)'' and will gain powers beyond belief.

The story takes place in AlternateHistory Japan, shortly after the [[UsefulNotes/WorldWar2 second great war]]. The Rokuhara Shogunate rules the country with an iron fist and their mass-produced brand of Tsurugi while being under administration by the occupying forces of the [[{{Eagleland}} GHQ]]. While the Shogunate suppresses the people with brutal force, the GHQ tries turning the land into a Military Base for their own needs. Naturally, both sides try to overthrow each other.

Unnoticed by all of this, a young man with name Kageaki Minato is roaming the land with his own Tsurugi, the blood-red ''Muramasa'' as an [[CowboyCop unofficial Police Man]], solving different incidents involving Tsurugi users and fighting the injustice of Rokuhara. His true motivation, however, is not nearly as noble. Kageaki is longing for {{Revenge}} for his massacred home town and broken sword, searching for the one responsible, Silver Star, one of the most powerful Tsurugi in existence and hunting it down. But Kageaki is no hero nor would he ever call himself a man of Justice. He merely wants to atone himself for his past sins and the people he murders and has murdered over the course of his journey.

''"The Demon I meet, the Demon I slay. The Saint I meet, the Saint I slay. This is the way of the sword!"''

This is the phrase that Kageaki says when fusing with Muramasa, and this is the phrase that tells both his past and his future…


Originally released in October 2009, on time to NitroPlus' 10th Anniversary. In 2010 the Fandisk ''Janen-Hen'', or Stories of Evil Thoughts, was released featuring a after story to the main plot to wrap-up the loose ends, [[AnotherSideAnotherStory different sidestories involving minor characters]] and some other nifty extras.

!!''Muramasa'' contains examples of:
* ZeroPercentApprovalRating: Nobody likes Rokuhara.
* ArcWords: ''"The Demon I meet, the Demon I slay. The Saint I meet, the Saint I slay. This is the way of the sword!"''(鬼に逢うては,鬼を斩る。仏に逢うては,仏を斩る。ツルギの理,ここに在り!)
** "You just killed me, you demon!"
* AManIsNotAVirgin: Kageaki.
* AlternateHistory: The existence of the [[spoiler:God of Metal]] and Dwarves / Emishi brought Tsurugis into the medieval battlefield.
** Japan maintained its Kamakura Shogunate, which was uprooted during an early stage of the Warring States period.
** The America colonies never left the British Empire, and it is a plot point.
** Socialism is discarded by European intellectuals.
** UsefulNotes/WorldWarTwo took place in the 1930s.
* AncientConspiracy: [[spoiler:The Society of the Green Dragon]].
* AnimeThemeSong: [[http://www.youtube.com/watch?v=Le2zxWrD294 MURAMASA]]
* AntiHero: Kageaki Minato wants to nail the page quote into every player's head.
* AntiVillain: There are some people who oppose Kageaki that are more moral than him. [[spoiler:Ichijou becomes one in her route's ending and the after story of the canon ending]]. Shishiku and the leaders of the Continental Army may count too as they fight for nothing besides their countries.
* AloofBigBrother: Misao. Not the case of Kageaki as he claimed.
* AnyoneCanDie: '''Absolutely anyone.'''
* ArmiesAreEvil: From the get-go it is established that the Rokuhara military forces are a bunch of ruthless, bloodlusting assholes who care not about innocent lives. At the start of the game it shows Rokuhara soldiers slaughtering and pillaging a little village simply because its citizens granted a fugitive shelter. The GHQ isn't much better but at least they don't kill random people just for the heck of it.
* AscendedMook: [[spoiler:The God Of Metal took its form and mind after a deranged old soldier first shown in Chapter 2]].
* AxCrazy: Ichizou Sorimachi
* BadassGrandpa: Masamune and Muramasa the First. Sayo is a badass grandma.
* BattleButler: Sayo Nagakura, to Kanae.
* BattleCouple: Kageaki and Muramasa the Third.
* BattleHarem: All of the heroines briefly team up in the Warlord arc.
* BeneficialDisease: [[spoiler:A coma caused by heavy metal poisoning on Hikaru made her synchronize better with Muramasa the Second]].
* {{BFG}}: The vibrocannons on Arahabaki and the Type 00 units. They're said to be able to change the history of warfare. The Guts Eider also has a 76mm cannon that fires HVAP rounds.
* {{BFS}}: Every Tsurugi is a robotic sword.
* BigBadEnsemble: The Rokuhara Shogunate and the GHQ appear to be the main antagonists at first. However, the "Tyrant" route eventually reveals [[spoiler: that the [[AncientConspiracy Society Of The Green Dragon]] are the ones who actually pull the strings behind the scene.]]
* BigScrewedUpFamily: The Ashikaga clan, ruling body of Rokuhara.
** The Minato family might count as well. Plus Kanae's family, the Ootori clan.
* BlackAndGreyMorality: Who exactly is the ultimate black is somehow debatable.
* BreakTheCutie: Too many.
* BrownNote: Ginseigou's song. It drives people insane and makes them slaughter each other.
* BrokenAce: The Ouji [[spoiler: older brother]].
* BodyHorror: Whoever is the user of [[spoiler: Masamune]] will experience this at full force.
* CampStraight: Imagawa Raichou.
* ChickMagnet: Kageaki.
* CombiningMecha: [[spoiler:[[NamesToRunAwayFromReallyFast Guts Eider]]]][[note]]A ShoutOut to GetterRobo and KotetsuJeeg[[/note]]. A very twisted version too.
* CrapsackWorld
* CuteBruiser: Ayame, Chachamaru, Inada and Hikaru.
* CycleOfRevenge: Specifically mentioned by Subaru as a reason never to kill. [[spoiler:This comes into play later on for poor Ichijou.]]
* DarkIsNotEvil: Kageaki Minato
* DarkerAndEdgier / BloodierAndGorier: This is by far NitroPlus grittiest, bleakest and most brutal entry, even compared to earlier works like ''VisualNovel/PhantomOfInferno'' or ''VisualNovel/SayaNoUta''. Even ''{{VisualNovel/Hanachirasu}}'' looks like a light-hearted ride through Candyland in comparison.
* DarkMessiah: [[spoiler:Kageaki in the canon ending develops an unique way to promote peace]].
* DecoyProtagonist: Yuuhi Niita. He and his posse are based on MuvLuv's Takeru Shirogane and co, [[spoiler:then deconstructed horribly.]]
* {{Deconstruction}}: The entire story deconstructs the concepts of Heroism and Justice. [[spoiler:That is, killing people that one considers to be evil is not inherently more reprehensible but one should not try to justify it with pretty words and ideals. According to the game, it is still a vile act]].
* DestructiveSavior: [[spoiler:The game of the trope, since Kageaki has to compensate the numbers of enemies slayed by offing the same amount of allies and innocent civilians.]]
** [[spoiler:Later, it is implied that he founds a mercenary army based on Muramasa's curse, leaving one of their employer's allies alive to spread the word of their price, so that people will become more reluctant to wage war.]]
* DisappearedDad: One of the main factors that sets [[spoiler:Hikaru]] in motion.
* DismantledMacGuffin: Muramasa's original blade. Kageaki has to kill holders of its fragments or it's spawns to retrieve them one by one.
* DontMakeMeDestroyYou: [[spoiler:Ichijou begs Kageaki to tell her that he had no choice but to kill all those innocent people, that he didn't want to do it, any excuse so that her ideals don't force her to kill him.]]
* DownerEnding: [[spoiler: Pretty much every ending.]]
* DroppedABridgeOnHim: [[spoiler: Moriuji Ashikaga]] [[KilledOffScreen dies off-screen]] in the "Hero" and "Revenge" routes, with only a Newspaper frontpage relating to it. He gets a bit more Screen Time in the "True Demon" route [[spoiler: before he's killed by Chachamaru]].
* {{Eagleland}}: The GHQ is pretty much the embodiment of Flavor 2.
** In the earlier chapters they are technically British instead of American, because the Continental Army lost the revolution. In the Tyrant arc they became the Continental Army.
* EnigmaticMinion: A lot of side characters are in fact members of the Continental Army or Society of the Green Dragon.
* EvilVersusEvil: Rokuhara versus GHQ.
* EyesAlwaysShut: Ootori Kanae. [[spoiler:She later subverts it, and turns out there was a [[FacialHorror good reason]].]]
* ForWantOfANail: Hikaru got heavy metal poisoning because of a modernized factory drained waste into a country river. This story hides a GreenAesop inside.
* GallowsHumour: The characters know they won't stay on the stage long.
* GambitPileup: Rokuhara, Royalists, GHQ, Continental Army, Society of the Green Dragon - every faction has a gambit.
* GoneHorriblyRight: [[spoiler: The awakening of the God of Metal.]]
* {{Gorn}}: Expect to hear "splat" a lot.
* HalfHumanHybrid: [[spoiler:Chachamaru is a half human, half Tsurugi, created when her mother forged her own soul into a Tsurugi while she was pregnant.]]
* HatePlague: Silver Star's song causes those hearing it go insane and start killing each other.
* HeroicBSOD: Pretty much any and all of the protagonists, but the biggest ones happen to Ichijou when her entire paradigm is challenged by circumstances. Repeatedly. Heck, even her Tsurugi suffers a BSOD at one point, it's so bad.
* HeroicWannabe: Ichijou Ayane and Yuuhi.
* HeroWithAnFInGood: Kageaki.
* HistoricalDomainCharacter: Hidden everywhere throughout the story.
* HonorBeforeReason: [[spoiler:Muramasa's curse.]]
* InfantImmortality:[[spoiler: Averted. The most extreme case is poor Greywand, "collected" by Kageaki minutes after she was spawned.]]
* [[KatanasOfTheRisingSun Tsurugis Of The Falling Sun]]: The Rokuhara army.
* KatanasAreJustBetter: The game of the trope.
* KillAllHumans: The motivation of the Silver Star's Musha.
* KillEmAll: You can pretty much count the characters who're still alive at the end on one hand.
* KillTheCutie: Being aesthetically pleasing and\or moral in this game guarantees a CruelAndUnusualDeath.
* LargeHam: Shinnou and Masamune.
** And '''"RUUUUUUBYYYYYY SAAAAAAACHAAAAAAANT!"'''
* LightIsNotGood: Silver Star [[spoiler:/ Hikaru Minato]].
* LoadsAndLoadsOfCharacters: Probably one of the biggest casts in a [[VisualNovel VN]] yet.
* LoveMakesYouEvil: [[spoiler: Hikaru.]]
* MadScientist: Professor Wolf Sievers. He's often referred as Prof. Underpants.
* MadnessMantra: Guts Eider.
* MeaningfulName: Ichijou's name is written in a way that refers to a straight and narrow path that is impossible to deviate from, much like her personality.
* MeaningfulRename: When he finally gets his original sword back, Kageaki decides to name it Kotetsu [[spoiler:which, in Chachamaru's ending, is revealed to be her Tsurugi name]].
* MiniMecha: Tsurugi are not really huge. Most of them are about 3 - 6 feet larger than a fully-grown human.
* MummiesAtTheDinnerTable: Doushin made his old friend-turned-enemy's head into a mask, both honoring and humiliating him.
* NoSenseOfDirection: Ichijou. Most notable in Chapter 2.
* OffingTheOffspring: Greywand and TheReveal.
* TheOjou: Kanae Ootori.
* OnlySaneMan: Shishiku Ootori is the most normal, practical and soldier like among the four lords of Rokuhara. He uses no extravagant decorations, does not cross dress, is not engaged in AncientConspiracies.
* PoweredArmor: The Tsurugis. Doubles as EmpathicWeapon too.
* PosthumousCharacter: Subaru Minato [[spoiler: and Yuuhi.]]
* ProudWarriorRace: It's common for Emishi (dark skinned, short people with pointy ears) and Dwarves (white, western equivalent) to brand their souls into tsurugi, and they're considered master blacksmiths.
* RapeAsDrama: Almost one per chapter.
* RelationshipValues: [[spoiler:Subverted.]]
* RobotGirl: Muramasa the Second and the Third. Plus [[spoiler:Chachamaru]]
* {{Samurai}}: Japanese who use Tsurugi are called Musha. Westerners who use Tsurugi are called Crusaders.
* ScarfOfAsskicking: Ichijou Ayane wears one.
* ShoutOut: The dream sequence where [[spoiler:Hikaru]] tries to find out what kind of girl Kageaki likes is a conga line of Nitroplus characters including [[VisualNovel/PhantomOfInferno Ein]], [[VisualNovel/{{Demonbane}} Nya]], [[VisualNove/SayaNoUta Saya]], and Super Sonico, the company's mascot.
* SissyVillain: Imagawa Raichou, but he's a very likeable example. The assassin Houma is a stranger example.
* StarfishAlien\EldritchAbomination: [[spoiler:The God of Metal. It's motif BGM is called ''Shining Trapezehedron'']].
* SugarAndIcePersonality: Shishiku Ootori.
* SuperRobot: With dwarves.
* TheGovernment: The Rokuhara Shogunate.
* VillainProtagonist: [[spoiler:Deconstructed.]]
* WarIsHell: The country still hasn't fully recovered from the brutality of the Rokuhara Shogunate. Violence begets more violence. Loyalties shift like the wind. [[spoiler:This is also connected to the true meaning of Muramasa's curse; it is actually supposed to expose the fact that there is no such thing as a just cause for war, hopefully revealing the true horrors of war to humanity and getting them to stop killing each other.]]
