Upon seeing the theatre being packed to capacity, director Harada thanked Oizumi for putting a lot of effort in the pre-release promotional run and expressed his wish to make a sequel if all goes well for this movie. In response, Oizumi and Toda both "complained" about the director taking too long to shout "Cut!" during the filming. In Oizumi's case, he had a scene where he was hanging from his neck and almost suffocated because the director simply wouldn't stop the filming. As for Toda, there was a scene where she had to carry Mitsushima on her back and climb up the stairs so she realised the feeling of being responsible for another person's life through that episode.
As Kiki Kirin couldn't be at the event on that day, she prepared a video message where she praised the movie for having such a good cast and crew that the viewers will feel that they got a good deal in the end since the movie would have cost at least 15 times more if it was made in Hollywood.
