Matsuyama will be playing the role of Naoe Kanetsugu who forms an alliance with Ishida to fight Ieyasu. Matsuyama commented that although many actors have played Kanetsugu to date, the movie's depiction of this character is slightly different from the past so he had fun playing him in this movie. Being able to work with Okada who he respects a lot was also a memorable experience for him.
On the other hand, Dan will be playing nun Myozen who is an old acquaintance of Shima Sakon (Hira), the right-hand-man of Ishida. Although her appearance time is limited, her character is a silent observer of the secret talks between Sakon and Ishida. Dan hoped that her acting would not affect the movie adversely in any way and called everyone to support the film when it is released.
