The fight between Ueda and one of the main antagonist's stooge in which both of their hands stretched long while punching each other is based from the devil fruit ability of Monkey D Luffy, the main character of the anime One Piece.

At one scene, Yamada was scene crawling similar to Sadako of The Ring Movie series while sleeping. Yukie Nakama, the actress who played Yamada achieved prominence after playing the said character in the film Ring 0: Birthday (2000).

Detective Yabe and his assistant only had two scenes in this film and never had an interaction with the other main characters.
