A brainwashing film featuring singing ladies who appear in an educational program, "AP Staff's Demon Collar" tells the story of Takeda, who has obtained a collar that has the ability to brainwash these smiling and energetic girls, who are very popular among men and women of all ages, into doing as he wishes. The storyline was well told, the actresses' performances were excellent, and the dark makeup and colored contacts, which are essential in brainwashing films, were used in an attractive manner. However, the depiction of brainwashing was weak, and there were areas for improvement, such as the size of the collars, the outdated costumes, and the lack of use of characters. Still, overall, it was a wonderful piece of work, and a third production is anticipated.
