Visual Novel / Full Metal Daemon Muramasa

"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 Visual Novel by Nitro+. It was written by Ittetsu Narahara (of Hanachirasu fame).

Tsurugi (劒冑) - These are powerful sets of armour which can only be crafted by 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 Alternate History Japan, shortly after the 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 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 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 Nitro+'s 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, different sidestories involving minor characters and some other nifty extras.

A spinoff, Series:Space is planned to be serialized in 2016.

Muramasa contains examples of:

  • 0% Approval Rating: Nobody likes Rokuhara.
  • Arc Words
    • : "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!"
  • Alternate History: The existence of the 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.
    • World War II took place in the 1930s.
  • Ancient Conspiracy: The Society of the Green Dragon.
  • Anime Theme Song: MURAMASA
  • Anti-Hero: Kageaki Minato wants to nail the page quote into every player's head.
  • Anti-Villain: There are some people who oppose Kageaki that are more moral than him. 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.
  • Aloof Big Brother: Misao. Not the case of Kageaki as he claimed.
  • Anyone Can Die: No exceptions.
  • Armies Are Evil: 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.
  • Ax-Crazy: Ichizou Sorimachi
  • Badass Grandpa: Masamune and Muramasa the First. Sayo is a badass grandma.
  • Battle Butler: Sayo Nagakura, to Kanae.
  • Battle Couple: Kageaki and Muramasa the Third.
  • Battle Harem: All of the heroines briefly team up in the Warlord arc.
  • Beneficial Disease: 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.
  • Big Bad Ensemble: The Rokuhara Shogunate and the GHQ appear to be the main antagonists at first. However, the "Tyrant" route eventually reveals that the Society Of The Green Dragon are the ones who actually pull the strings behind the scene.
  • Big, Screwed-Up Family: The Ashikaga clan, ruling body of Rokuhara.
    • The Minato family might count as well. Plus Kanae's family, the Ootori clan.
  • Black and Grey Morality: Who exactly is the ultimate black is somehow debatable.
  • Break the Cutie: Too many.
  • Brown Note: Ginseigou's song. It drives people insane and makes them slaughter each other.
  • Broken Ace: The Ouji older brother.
  • Body Horror: Whoever is the user of Masamune will experience this at full force.
  • Camp Straight: Imagawa Raichou.
  • Chick Magnet: Kageaki.
  • Combining Mecha: Guts Eidernote . A very twisted version too.
  • Crapsack World
  • Cute Bruiser: Ayame, Chachamaru, Inada and Hikaru.
  • Cycle of Revenge: Specifically mentioned by Subaru as a reason never to kill. This comes into play later on for poor Ichijou.
  • Dark Is Not Evil: Kageaki Minato
  • Darker and Edgier / Bloodier and Gorier: This is by far Nitro+'s grittiest, bleakest and most brutal entry, even compared to earlier works like Phantom of Inferno or Saya no Uta. Even Hanachirasu looks like a light-hearted ride through Candyland in comparison.
  • Dark Messiah: Kageaki in the canon ending develops an unique way to promote peace.
  • Decoy Protagonist: Yuuhi Niita. He and his posse are based on Muv-Luv's Takeru Shirogane and co, then deconstructed horribly.
  • Deconstruction: The entire story deconstructs the concepts of Heroism and Justice. 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.
  • Destructive Savior: 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.
    • 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.
  • Disappeared Dad: One of the main factors that sets Hikaru in motion.
  • Dismantled MacGuffin: Muramasa's original blade. Kageaki has to kill holders of its fragments or it's spawns to retrieve them one by one.
  • Don't Make Me Destroy You: 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.
  • Downer Ending: Pretty much every ending.
  • Dropped a Bridge on Him: Moriuji Ashikaga 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 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.
  • Enigmatic Minion: A lot of side characters are in fact members of the Continental Army or Society of the Green Dragon.
  • Evil Versus Evil: Rokuhara versus GHQ.
  • Eyes Always Shut: Ootori Kanae. She later subverts it, and turns out there was a good reason.
  • For Want of a Nail: Hikaru got heavy metal poisoning because of a modernized factory drained waste into a country river. This story hides a Green Aesop inside.
  • Gallows Humour: The characters know they won't stay on the stage long.
  • Gambit Pileup: Rokuhara, Royalists, GHQ, Continental Army, Society of the Green Dragon - every faction has a gambit.
  • Gone Horribly Right: The awakening of the God of Metal.
  • Gorn: Expect to hear "splat" a lot.
  • Half-Human Hybrid: Chachamaru is a half human, half Tsurugi, created when her mother forged her own soul into a Tsurugi while she was pregnant.
  • Hate Plague: Silver Star's song causes those hearing it go insane and start killing each other.
  • Heroic B.S.O.D.: 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.
  • Heroic Wannabe: Ichijou Ayane and Yuuhi.
  • Hero with an F in Good: Kageaki.
  • Historical-Domain Character: Hidden everywhere throughout the story.
  • Honor Before Reason: Muramasa's curse.
  • Infant Immortality: Averted. The most extreme case is poor Greywand, "collected" by Kageaki minutes after she was spawned.
  • Katanas Are Just Better: The game of the trope.
  • Kill All Humans: The motivation of the Silver Star's Musha.
  • Kill 'em All: You can pretty much count the characters who're still alive at the end on one hand.
  • Kill the Cutie: Being aesthetically pleasing and\or moral in this game guarantees a Cruel and Unusual Death.
  • Large Ham: Shinnou and Masamune.
  • Light Is Not Good: Silver Star / Hikaru Minato.
  • Loads and Loads of Characters: Probably one of the biggest casts in a VN yet.
  • Love Makes You Evil: Hikaru.
  • Mad Scientist: Professor Wolf Sievers. He's often referred as Prof. Underpants.
  • Madness Mantra: Guts Eider.
  • Meaningful Name: 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.
  • Meaningful Rename: When he finally gets his original sword back, Kageaki decides to name it Kotetsu which, in Chachamaru's ending, is revealed to be her Tsurugi name.
  • Mini-Mecha: Tsurugi are not really huge. Most of them are about 3 - 6 feet larger than a fully-grown human.
  • Mook Promotion: The God Of Metal took its form and mind after a deranged old soldier first shown in Chapter 2.
  • Mummies at the Dinner Table: Doushin made his old friend-turned-enemy's head into a mask, both honoring and humiliating him.
  • No Sense of Direction: Ichijou. Most notable in Chapter 2.
  • Offing the Offspring: Greywand and The Reveal.
  • The Ojou: Kanae Ootori.
  • Only Sane Man: 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 Ancient Conspiracies.
  • Powered Armor: The Tsurugis. Doubles as Empathic Weapon too.
  • Posthumous Character: Subaru Minato and Yuuhi.
  • Proud Warrior Race Guy: 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.
  • Rape as Drama: Almost one per chapter.
  • Relationship Values: Subverted.
  • Robot Girl: Muramasa the Second and the Third. Plus Chachamaru
  • Samurai: Japanese who use Tsurugi are called Musha. Westerners who use Tsurugi are called Crusaders.
  • Scarf of Asskicking: Ichijou Ayane wears one.
  • Shout-Out: The dream sequence where Hikaru tries to find out what kind of girl Kageaki likes is a conga line of Nitroplus characters including Ein, Nya, Saya, and Super Sonico, the company's mascot.
  • Sissy Villain: Imagawa Raichou, but he's a very likeable example. The assassin Houma is a stranger example.
  • Starfish Alien\Eldritch Abomination: The God of Metal. It's motif BGM is called Shining Trapezehedron.
  • Sugar-and-Ice Personality: Shishiku Ootori.
  • Super Robot: With dwarves.
  • The Government: The Rokuhara Shogunate.
  • Villain Protagonist: Deconstructed.
  • War Is Hell: The country still hasn't fully recovered from the brutality of the Rokuhara Shogunate. Violence begets more violence. Loyalties shift like the wind. 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.
