This katana is a replica of a sword from the movie 47 Ronin which was released in 2013. The main plot of the movie was based on actual events that happened in 18th century Japan. The story centers on the plan of 47 leaderless samurai (ronin) to avenge their feudal lord Asano Naganori by killing a court official named Kira Yoshinaka who caused the former to commit seppuku or ritual suicide.

The magical swords were used by the 47 to exact their revenge upon Kira and restore their honor.
