The Myth of Murakumo
The Weapon it's self is shrouded in mystery and legend. This tale might sound kinda familiar to anyone who has ever played a certain game (+1 if you are the first to guess right). Now the Full Name of the Murakumo is Ame-no-Murakumo-no-Tsurugi or Sword of Gathering Clouds of Heaven. The Legend of the Murakumo is written in the Japanese Myth Book called Kojiki.
The Story takes place in japan and starts when Susanoo encounter a grieving family of Kunitsukami or Gods of the Land. Essentially a Giant Monster with 8 heads has ravaged their family and eaten seven of the family's eight daughters. After doing a bit of recon Susanoo came up with a plan to defeat the Monster known as Yamata-no-Orochi. The only price the Susanoo demands in return for his help is the last daughter's hand in marriage which they accepted. After Turning the eight daughter into a Comb Susanoo Places eight Vats of Sake Upon eight Platforms while Yamato-no-Orochi was getting liquored up Susanoo lopped off each of his eight heads and four of his tails. After cutting off the fourth tail he found the Murakumo which gave to Amaterasu to settle an old feud.
Murakumo a few generations later was given to Yamato Takeru from his aunt Yamato-Hime. He later used Murakumo to cut grass after a treacherous WarLord tried to burn him to death by lighting grass on fire during a hunting trip. He used Murakumo to slice the burning grass removing the source of the flame. He renamed the sword Kusunagi-no-Tsurugi or Grass Cutting Sword. So essentially our Murakumo came from being a sword of the gathering clouds of heaven to a weed whacker. What a downgrade.
The Weapon supposedly exists today but it has a tendecy to get lost, stolen or otherwise removed from public view.
The First story is that it is in Asuta Shrine and that it is not for public display. During the Edo Period a Monk did claim to have seen the sword. He described it as well maintained, shaped like a sweet flag with a white metallic color.
According the tale of Heike (a collection of oral stories) the Murakumo was lost a sea after the leaders of the Heike clan were defeated in a naval battle. Thenthe leaders commited suicide they took a sacred Jewel and Murakumo with them (the jewel was later recovered).
The Tenth Emporer Sujin has supposed created a replica of the sword. The Sword was later stolen although the royal family claims that the Replica was stolen not the sword it's self. The possibility of the real one being stolen and the fake still being there is just as likely.
Murakumo the Review
The Murakumo is a decent weapon if you have the Strength and Dex to wield it. While being limited only towards slash attacks it makes for this with a high starting damage. Because the sword is large it's attacks are kinda slow but they can sweep taking out multiple opponents at once (I would swap the weapon for one on one encounters). Despite requiring 28 strength to wield it only has an E scaling with strength which is a huge investement for a dex build. The reason why I say this is because the weapon has a B scaling in dex. It is largely impractical for strength builds. While the Murakumo looks nice and has high damage there are better alternatives for it's role. If you are running a Dex Build the Uchigatana, the Iato and the Washing pole are better picks if you are running a strength build the just about anyother great sword will do the job better than the murakumo. It can be buffed but then again so can most other weapons. I'd give the weapon 6/10 it is a decent weapon it does what it does very well but there are just better options out there.
