Lily Frankie will be playing Hirai and this choice was said to be at the request of Fukumoto who felt that Lily was the best person to project the aura and charisma of the character. In response to this, Lily commented that it is difficult to act in a production based on original material especially with the fans' expectations but he hopes that they will be more lenient towards him.
