## Plot

In the story, a Tsurugi (劔冑) is a set of armor forged from a living soul. It's among the most powerful weapons in the world. Those who wear the armour are called Musha (武者) – warriors with the power of flight and blades able to beat steel.
In the island nation of Yamato, governed by the Rokuhara Shogunate in the first half of the 20th century, rumors of a Musha clad in silver armor, only known as Ginseigo, the Silver Star, begin to spread calling them a tyrant and despoiler.
One Musha, an old nemesis of the Silver Star, uses a crimson Tsurugi called Muramasa in his quest to bring them down. However, his Tsurugi comes with a dark past when five centuries ago it brought about a great calamity on the land.

## Characters
### Main characters

Minato Kageaki
Voiced by: Takuma Terashima as "Yuusuke Ishikawa"
A young man secretly working under orders from the prince to subjugate the Silver Star. His Tsurugi is Muramasa. While on a mission, he introduces himself as a policeman working part-time for the Kamakura Police Department; under normal circumstances, he spends his days in his cell at the Kamakura Detention House as an unconvicted prisoner due to committing a variety of crimes, including matricide.
While his outward appearance might indicate a person of dark and melancholic demeanor, in reality, Kageaki is a kind and honest young man. He acts as an airhead from time to time, much to the surprise of his peers.
Due to the various murders, he had committed under the tormenting influence of the curse known as the "counterbalance of good and evil", he views himself as a monster, his blade deep crimson with the blood of innocents. While he is well-versed in the art of war, he is by no means an expert combatant.
His reason for using Muramasa is twofold: for one, Muramasa is the only Tsurugi capable of withstanding the corruption of the Silver Star's "eggs"; additionally, he feels it is his duty as a brother to put an end to his sister's atrocities. His final wish upon finally defeating the Silver Star is to be judged and executed for all his sins.
Muramasa
Voiced by: Shimazaki Haruka as "Ayana Sumoto"
Third-generation Seishuusengou Uemon-no-jou Muramasa. Female. She was once housed in the depths of the Minato residence, but due to various circumstances, made a contract with Kageaki. The two of them are now working together as partners in stopping the Silver Star.
Her body is of steel, a characteristic that is reflected in her cold demeanor. However, she is more attentive toward Kageaki, who is deeply tormented by his curse. She became a Tsurugi in order to prevent her mother from being melted down as punishment for the unimaginable bloodshed she had caused during the Nanboku-chō wars; by becoming a Tsurugi, Muramasa was to watch over her mother, and stop her should she awaken to bring calamity upon the land once again. She is also acting out of a deep sense of guilt because her mother, the Silver Star, was the very being who had previously destroyed Kageaki's peaceful daily existence. However, she had never once voiced these feelings.
Although she adheres to the tenets of the "counterbalance of good and evil" that her mother and grandfather also followed, she, too, is tormented by constant feelings of guilt. During her mortal years, she was a stunning dark-skinned beauty. However, this was mainly due to the increased growth rate of Emishi, and in reality, Muramasa is much younger than what her outward appearance would suggest. Because of this, she can be somewhat naive and childish at times. In one of the game's routes, she gains the ability to turn into her human form once again and ends up showing a more emotional side of herself.
In particular, she has absolutely no experience in matters of the heart. One time, when Kageaki decides to clean her armor on a whim, she mistakes it for a genuine sexual assault and cries out in tears; another time, when Kageaki reaches out to her with kindness, she is too shaken up to answer and merely continues to tremble in silence.

## Development

Full Metal Daemon: Muramasa was written by Japanese scenario writer and Ko-ryū kenjutsu expert Narahara Ittetsu. It was the last game he wrote before leaving Nitroplus. Much like his earlier game Hanachirasu, it is also set in an alternate history, although it's not set in the same universe as Hanachirasu. The game also serves as a commemoration of Nitroplus' 10th anniversary and was the first Nitroplus game to use widescreen as well as vertical writing. The music group ZIZZ STUDIO composed the soundtrack for the game, art was handled by NamanikuATK, the tsurugi designs were done by Ishiwata Makoto, and the game was produced by Digitaro and Shima Nagare, the latter of whom is the scenario writer for Project VERMILLION.
J-List opened up preorders for the Western Collector's Edition for the game on August 20, 2021, featuring a 7" vinyl soundtrack record, art book, guidebook, happi coat, and a game DVD.

## Music

Along with the soundtrack, the game features the opening song "MURAMASA" performed by Masatoshi Ono, the insert song UZUKI by VERTUEUX, and the ending songs "Rakuyou", "Fuel My Soul" and "The Call" by Kanako Itō, Kazuhiro Watanabe and Yukky, respectively.
