Originating from the Shogunate of Katana, it is said that a curse was placed upon this ship by pirates while out at sea. As a result, the ship is now haunted with souls killed in naval battles by the crew of The Muramasa and the past crew of the vessel itself. It has been crafted with particular attention to detail and has several strengths as a result of the curse, one such is that the vessel lets out daunting and horrific cries when approaching an enemy, unerving opponents. The vessel was made by the students of the craftsmen who built The Masamune, and is named after the famous swordsmith.
