The movie which is based on the manga by Samura Hiroaki, features Kimura in the leading role of a samurai Manji who is renowned for having killed 100 people and becomes immortal when a mysterious old lady gives him eternal life. One day, he is engaged by a young girl named Asano Rin (Sugisaki) to be her bodyguard and take revenge against Itto-Ryu which is a group of skilled swordsmen. He accepts the job reluctantly because Rin looks similar to his late younger sister.
In the scene where Kimura had to fight against 300 people with his right eye concealed, he went ahead with the filming with no-stand-in. During the filming, he slipped on the gravel and suffered a serious injury to his right knee's ligament so he had to get painkillers injected in order to continue with the shoot. Having seen that the director continued with his work despite suffering a fracture in his right ankle during the filming, Kimura was impressed with his dedication and wanted to continue with the filming. Even during scenes which did not involve him, Kimura was always on the set and even brought massage machines to give massages to the cameramen.
