The movie is a remake of Ninomiya's 2014 independent film "Nemureru bijo no genkai" which won the judges' special award at the 2015 Yuubari International Fantastic Movie Festival. Sakurai plays the lead character Oria Aki who works as a magician's assistant in a circus troupe and has no purpose in life. As she gets hynoptised during a stage performance, she finds herself wandering between reality and an imaginary world where the only pleasant memories she has are those with her boyfriend Kaito (Takahashi).
Sakurai said that it had been a year since they filmed this movie and she was thankful that the movie is finally ready to be watched by the audience. Likewise, Takahashi also echoed her view and said that it was an enjoyable experience to be able to work on this movie.
